Hannah Layton aka Layton
Hannah Layton aka LaytonPractice Administrator
Hannah grew up on the coast of Maine with her parents, a younger sister, and a myriad of family pets. While in high school, she job shadowed a veterinarian for a year; and that’s when she realized her passion for helping our four-legged family members in some capacity. Fast forward a few years, Hannah was offered a reception position at a local veterinary practice. She jumped at the opportunity and stayed for eight years.

With extensive small animal knowledge, Hannah went to work for an animal ophthalmology practice, where she gained knowledge of the treatment for glaucoma, cataracts, and other ophthalmic issues. Eventually, she moved back into small animal care, where she enjoys cultivating a rapport with both clients and their pets, watching the young patients grow into mature companions, as well as, watching our client’s families as they grow too.

Hannah’s home life is shared with her sweet rescue, lab-mix, Marley; where they enjoy watching football together. She also enjoys traveling and going to concerts. We are so glad that Hannah and her compassion for animal care have found their way to us.

Stefanie Wilder
Stefanie WilderPet Facility Manager
A native of Powder Springs, Stefanie always knew she wanted to be in veterinary medicine. She first started her veterinary career at another local clinic. During her seven years there, she worked her way up through several positions, including Kennel Manager, Head Technician, and Clinic Manager.

In the fall of 2014, Stefanie became part of the KMAH family as a Veterinary Assistant. While assisting our amazing doctors, she enjoyed running laboratory samples, monitoring anesthetized patients, and participating in dentistry. The amazing and rewarding part was getting to form lasting bonds with our patients and their loving owners. She now gets to strengthen those bonds, as well as, forming new ones while “vacationing” with our Pet Resort guests, as she oversees the care, comfort, and health of the animals visiting our Pet Resort and Training facility.
When she and her husband are not on the go with their two active boys, Stefanie enjoys running, baking, and traveling. The Wilders share their life with a German Rottweiler named Beans (aka Beanie Baby), whose favorite toy is his food bowl; a sweet little mixed breed dog named BB, who absolutely loves his Kong; and two guinea pigs named Wreck it Ralph and Kitty Pig.

Tina Payton
Tina PaytonMarketing Specialist
Tina was a client of KMAH for seven years before she came to work for us with a strong sales and marketing background. Her position at KMAH is her dream job as it fuses two of her passions, animals and being creative. She spent over a year as receptionist to learn the practice in preparation for her role as Marketing Specialist.

Her previous sales/marketing experience has been in corporate environments, with the most recent being within the Nashville music industry. She lived in Nashville for four years where she worked behind the scenes in artist development, production, publishing and licensing. Working with the songwriters behind the songs and the artists that perform them was an incredible experience for Tina.

Tina’s time on the desk was an invaluable education in the veterinary industry, especially since she learned from the best in the business. Based on her experience, Tina wishes all pet parents would educate themselves on pet health and take a more active role in their pet’s wellbeing, opposed to enabling their pets to suffer because they’re not in tune with their health. They can’t speak for themselves, so we humans must educate ourselves and act for them.

Tina has two K9 kids: Woot, a 12-year-old Rat Terrier, and Cody, a 9-year-old Boxer/Greyhound mix, of which both are overachievers at being mom’s favorite. Life away from the hospital consists of her two furbies, good music (classic rock, blues, etc.) and documentaries with comedies intermingled, as it satisfies her creative, knowledge-seeking and humorous personality.

Born in Atlanta and raised in Kennesaw, she excelled in basketball during her school years and really enjoys reconnecting with her childhood friends as many are clients of KMAH. For Tina, it’s great to be home again and especially awesome to be a part of the KMAH Family.

Jeremy Ernst-Verhine, LVT
Jeremy Ernst-Verhine, LVTLicensed Veterinary Technician
Caring for others through the power of medicine is simply in Jeremy’s nature—both of his parents worked as emergency medical technicians, and he even served as an EMT himself for a time. His passion for medicine, coupled with his adoration of animals, makes veterinary medicine the perfect career choice! Jeremy has been a veterinary professional for more than 18 years.

Jeremy is an Atlanta native and first began his animal-care journey at a clinic in Marietta. After nine years, he moved to Virginia and started working for a low-cost spay-and-neuter clinic affiliated with the local Humane Society. Next, Jeremy moved back to Georgia in 2012 and worked for a pair of hospitals in the area before joining the Kennesaw Mountain Animal Hospital family in the fall of 2016.
Around the clinic, Jeremy enjoys working with difficult patients and loves applying his knowledge of animal behavior to real-world cases. He’s also passionate about educating clients on proper pet care in order to ultimately improve the lives of the area’s families.
Jeremy and his wife, who works as a Manager for Pike Nursery, shares their lives with four cats named Cooper, Weibe, Fordon, and Phaecyt as well as, a pair of dogs who go by Nala and Tag. They also have a bird, Inky.

Mercy Lawler
Mercy LawlerVeterinary Assistant
Mercy began her original career path as an Undergraduate at Georgia State in English Literature. But soon realized her true calling was caring and being an advocate for pets in need. Specifically, Mercy’s main interest is geriatric pet care and exploring ways to improve their quality of life. Because pets can’t communicate exactly what they’re feeling, each case is a mystery that needs to be solved. It’s the thinking outside the box and constant state of problem solving that holds Mercy’s interest and keeps her humble.

After adopting her first dog, she realized how bad the overpopulation is and began to get involved with rescue and local shelter organizations. Fostering sick, injured, or unhealthy animals meant frequent visits to the vet and the catalyst she attributes to becoming a Veterinary Assistant.

Mercy hails from Norcross and is the oldest of seven siblings, two of which have Down Syndrome (a brother and an adopted sister). Coming from a loving family, where their home was always open to anyone in need physically or emotionally, has influenced how Mercy lives her life today. Which is evident by the number of rescues and fosters that she has opened her home to. With four dogs and seven cats…all rescues, most were fosters that were never adopted so they became her children. Mercy is a special foster mom, she cares for the ones with severe illnesses or unique disabilities. Most Currently her canine pack consists of an elder Pit Bull named Sybil; Cosmo, an epileptic Cocker Spaniel; Lewis, an elder Shih Tzu with no eyes and heart disease; Squirt, a young epileptic, current foster. Her feline clowder includes, Fern, Eudora, Batou, Dirt McGirt, Shinji, Willard, and Abby. As is evident, Mercy embodies the true meaning of care and compassion; coupled with her knowledge and commitment to the wellness of all animals, it makes Mercy a perfect fit for our Family.

Tonya Davis
Tonya DavisVeterinary Assistant
Tonya’s journey to becoming a Veterinary Assistant began in elementary school at an overnight field trip to a zoo. She experienced the behind the scenes operations by learning about the animal’s habitats, evening and morning rituals, sleeping habits, and communication, etc. As soon as she was of age to work, she began working as a kennel technician at a local veterinary clinic. Tonya continued her career at clinics and eventually becoming a Veterinary Assistant.

She is intrigued most with surgical procedures and internal medicine, as she finds if rewarding to correct an injury or discover the root of a problem that saves a life. While the technical aspect of problem solving is a major interest to Tonya, she finds true fulfillment in comforting patients to maintain a calmness so they can heal properly.

A native of Peachtree City, she has always enjoyed biology, the outdoors, kayaking, music and movies. She and her boyfriend, Michael, are the proud pet parents to an elderly Chihuahua named, George, described as “the boss of the house”; a young Terrier mix named, Caffrey, described as a “circus act”; a young Pitbull mix named, Maverick, described as “the police”; a Teddy Bear Hamster named, Peggy; a Greek Tortoise named, Tina; and a Russian Tortoise named, Arthur. Their self-proclaimed “Zoo” also includes a small saltwater aquarium with snails, crabs and a starfish. Tonya’s experience, compassion and humor fits in well with her KMAH family.

Matthew Evans
Matthew EvansVeterinary Assistant
Matthew comes to KMAH with 13 years of experience in the veterinary care industry, it was his first job and he made a career out of it. Aside from his technical knowledge, he’s a natural with comforting our patients while under our care.

With his quick sense of humor and apparent need for attention (lol), Matthew keeps us laughing every chance he gets. He excels in photobombing pictures, loves Nerf gun battles, gaming, miniature gaming and painting miniatures of his favorite gaming characters.

He is the proud parent of Luna (a sweet chihuahua mix), Spock (a Teacup Rottweiler mix), and Parker (a Havanese mix). When he’s not gaming or painting, he enjoys cooking, and really enjoys spicy dishes. We are fortunate to have Matthew and his sense of humor part of the family.

Danyell Sistilli
Danyell SistilliVeterinary Assistant
Danyell has felt a natural connection with animals ever since her earliest days growing up here in Kennesaw. She recalls attending a petting zoo as a child, where she got separated from her mother for a short period. When Danyell’s mother found her, she was sitting on the ground petting a squirrel—the animal wasn’t even a part of the petting zoo! Danyell’s passion for animals has simply never wavered.

Danyell’s animal-care journey started when she was only 16 years old and began working at a local animal hospital. She then became a groomer at a dog salon before deciding to pursue the medical side of animal care once again. In April of 2016, Danyell joined the Kennesaw Mountain Animal Hospital family as a Kennel Technician, where she enjoys getting to know each-and-every pet that she comes across. Her work here provides great hands-on experience that serves her well during her collegiate studies in veterinary medicine!

As of May 2019, she is currently in school to become a Veterinary Assistant. When time permits between her busy work and school schedules, Danyell enjoys hiking in the great outdoors, swimming during the summers, and spending time with her own pets at home. She and her mother have two dogs; sweet and loving Oscar; and Rags, the grumpy old man.

Blake Tarnoff
Blake TarnoffKennel Assistant
Blake’s interest in animals stems back to her childhood pet dog, Ellie, who passed suddenly due to internal issues. With Science being her favorite subject, Blake needed to understand why Ellie passed and that ignited her interest in the medical aspect of pets.

A native of Marietta, her older sister has been a big influence as she has fostered many dogs and worked with rescues. With two cats, Nikki and Marley, she continues to grow her love for animals. Marley has learned to play fetch and mom couldn’t be more proud of her kids. She enjoys being active outdoors most of the time and experiencing new and exciting places through travel.

Kim Smith
Kim SmithClient Services Specialist
Kim’s journey began working reception in a doctor’s office, where she began learning
about medical terminology and interesting studies that were being performed. As animals are a large passion of hers, she pursued work in the veterinary industry landing a position in an animal hospital, and eventually came to work for KMAH. She is truly fascinated by the medical aspect of her position and finds the relationships with clients and their pets most gratifying.

A Georgia native, Kim is the oldest of four siblings and spends time with them often, attending any event that is music-related. As kids, they shared your not-so-typical family pets, such as an iguana, snake, and at one point a tarantula. She and her fiancé, Jordan, have a one-year-old named, Jack. She loves taking Jack to the park for fun days when she’s not playing in the yard with their other “children”. The family pack consists of a 110 lb. Doberman named Craig; a Collie mix named, Luna; and a tiny Terrier named, Molly. We’re grateful for Kim’s leadership and glad to have her as a Family member.

Jane Thornton
Jane ThorntonPractice Manager
Jane recalls waiting outside of her parents’ house for squirrels as a child, holding a peanut in her hand to entice the little creatures into coming close. She developed patience and a rapport with animals; the squirrels developed big bellies! Jane has always known that a career in the veterinary world would be a dream come true.

An Atlanta native, Jane worked as a legal assistant for many years before volunteering at an animal hospital, which jumpstarted her desire to work in the veterinary field. Dr. Carrie Friedewald had been Jane’s own veterinarian at another animal clinic, and Jane jumped at the chance to join forces. She’s been a member of the Kennesaw Mountain Animal Hospital family since its inception.

Lisa Kruse

What better way to spend your days, she mused, than by taking care of the pets who give so much to us? After working as kennel technician for two years, Lisa was appointed the designation of Kennel Manager and proudly serves our clients and their pets.

In addition to making sure the kennel functions smoothly, she is responsible for keeping things clean and making sure the clinic’s boarding pets are comfortable and happy. Her favorite part of the job is working alongside her talented and compassionate coworkers to better the lives of pets on a daily basis. She and her husband have an adorable, three-legged dog named Bella, and a Sphynx named Paxton. She also maintains feedings for a “herd” of strays that frequent their property.

Robin Robinson
Robin RobinsonTechnician Manager
Robin has adored animals ever since her earliest days, a trait she suspects came from her mother. She was constantly bringing home strays and couldn’t get enough of veterinary books and animal-related television programs. For Robin, a career spent helping pets every day simply made perfect sense. Now, she does just that as a Veterinary Technician!

Originally from Gadsden, Alabama, Robin started her journey in veterinary care at a clinic in Rainbow City. She then worked at a Southside, Alabama animal hospital before relocating to Georgia with her husband. Robin was thrilled to join the Kennesaw Mountain Animal Hospital team as a Veterinary Assistant which lead to her appointment as Technician Manager.

Along with her husband, Rick, her son, Gage, and her step-daughter, Emorie, Robin shares her life with four cats: Kairi, Bella, Balor and Samuel, as well as, an excitable dog named Nellie, a gecko, and a fish.

She and her husband are huge fans of The Walking Dead and have even visited most of the filming sites and met many of the show’s stars!

Cheyenne McTyre
Cheyenne McTyreDay-Play Manager - Trainer
Cheyenne’s passion for dogs and their behavior stretches back to her childhood. An inquisitive child, she was always seen carrying breed encyclopedias and training manuals. She soon realized some pet owners give up their pets to shelters due to behavioral issues. It then became a mission to save as many dogs from shelters by teaching pet owners how to create a well-balanced family companion so they can stay in a loving home.

After graduating high school, Cheyenne mentored and eventually went to work for a certified trainer. She began her career training, supervising group play, running puppy socialization and enrichment programs for puppies in their critical development period.

She is now in her element overseeing our Day-Play Program, and teaching Puppy Preschool, Day Training and Basic Manners Programs for KMAH. Her expertise ensures a fun and safe day of play as she determines the best fits for each group and constantly monitors their body language and reactions. Furthermore, through our Puppy Preschool, Cheyenne lives out her childhood dream to help pet parents start their new family members off on the “right paw” to prevent future behavior problems.

A native of Powder Springs, her time away from KMAH is devoted to the two loves of her life; a German Shepherd/Husky mix named, Mayday; and an 18-year-old Tennessee Walking Horse named, Sassy. Between the two, there’s lots of barn time, relaxing trail rides, and adventurous trail walks. Photography and reading round out the remainder of her time away from work.

Marissa Bibbs
Marissa BibbsGroomer
Marissa’s personality is one that blends perfectly with grooming. As a yoga and meditation instructor, she possesses a calm about her that our client’s pets pick up on. She has groomed cats and dogs that prior to her, would need to be sedated to groom, now they are groomed regularly without stress or drugs.

She enjoys volunteering at farms, as it puts her in touch with all kinds of wildlife. Which explains how she became the mother of a sweet pig named, Layla. Layla shares mom’s affection with two cats, Mercedes and Mitzi, several fish and an Axolotl named Casper. Casper is a Mexican Walking Fish that does different poses in his aquarium to get Marissa to feed him…kind of like Layla pig.

A Georgia native, Marissa practices Buddhism and Hinduism, enjoys art, music, dance, and hula-hooping. An avid outdoors person, she hikes the Appalachian Trail, does caving, practice shoots at gun ranges, and loves music festivals. As a very compassionate person, Marissa has great empathy for animals and their owners and is grateful to play a role in helping them get the most out of life. Marissa believes through confidence, skill, love, and compassion, a pet can relax enough to view grooming as a positive experience. Marissa embodies the calm, stress-free mindset that we pride ourselves on and couldn’t be happier to have her as part of the Family.

Hannah Brown
Hannah BrownClient Services Specialist
Hannah began as a pre-k teacher, as her compassion for all things small was a great fit. One day her veterinarian asked if she would be interested in coming to work for their practice. It was a no-brainer for Hannah since she absolutely loves everything about helping animals in need and providing care for them.

As she gained knowledge about veterinary medicine, Hannah found it truly fulfilling to educate clients about best practices for their pets. Fast forward two years…Hannah heard amazing things about KMAH and knew we would be a great fit as our values mirrored hers when it comes to providing the highest level of care for animals. Hannah became one of the family just before we opened the new facility in March of 2018.

Growing up south of Atlanta, Hannah is the youngest of four siblings. A true tom-boy, she could be found catching lightning bugs, crickets, or worms. She spent lots of time at her neighbor’s house playing with their kitties. She began playing soccer at age five, which turned into a life-long hobby, where she plays in an adult soccer league every weekend. She’s grateful for the friends she’s made along the way and the leadership skills it has taught her; not to mention fueling her competitive personality. Her most memorable moment was when she received an award for most goals scored in one season…a high school record. A self-proclaimed “Cat Lady”, Hannah owns several kitties: Raiden, Ponyo, Nori, Severus and Meryl. She somehow finds time to foster kitties too. They are her children and bring so much joy to her life. Hannah is active with feline rescue and fostering organizations and is more than happy to share her knowledge of rescue and fostering. Hannah’s caring nature is the perfect fit for our Family and we’re glad she’s here.

Theresa Munn
Theresa MunnClient Services Specialist
Theresa’s early education consisted of all the science electives in high school because she wanted to pursue a career in Marine Biology. After graduation she switched her focus and attended Kennesaw State University where she completed her BBA in Marketing. Upon graduation from KSU, she began working for a grooming salon as a bather.

One year later, she found herself working at a daycare/boarding facility. While there, she experienced a breakthrough with a rescued puppy mill dog named, Bebe. Bebe was scared and untrusting of the new environment, so Theresa dedicated each day Bebe was dropped off to easing her stress and gaining her trust. Her success with Bebe was the catalyst that steered her towards staying in the pet industry.

After five years she began her search for a new challenge and KMAH had exactly what she was looking for. Theresa works in our Pet Resort and enjoys interacting with our clients and their pets. A native of Mableton she now resides in Kennesaw and is the proud pet parent of three rescues: Spock, a young mix that looks like a miniature Rottweiler/Dachsund…she refers to Spock as a “Teacup Rotty”; Parker, a young Havanese mix; Tango a feline elder that looked after her beloved Springer Spaniel, Coby, in his final years; and Luna, a sweet chihuahua mix. Spock, Parker, and Luna loves hiking with mom, kayaking, and Parker loves fishing. When she’s not at KMAH, hiking, or kayaking, Theresa loves to cook. Theresa brings a level of knowledge and compassion that fits so well with our family and we are grateful to have her with us.

Mallory Maness
Mallory ManessClient Services Specialist
Early on, Mallory felt because she enjoyed working with the public and her excellent customer service skills, working in retail was the perfect fit for her. But her large heart and immense compassion for animals set her on a mission to combine her skills with the care of pets. She searched and found a position with a local animal hospital, where she quickly realized she was where she needed to be.

Eventually, after hearing about KMAH, she felt it would be a great fit for her to work with our awesome family…and she was right.

An Atlanta native, Mallory is the youngest of three siblings. Growing up she enjoyed piano and playing softball and tennis. Fast forward to present day, she and her husband are proud pet parents of three rescues; two pups named Rocky and Kona, and a grey Tabby named Alley. Personally, Mallory is a real go getter, always willing to step up and handle any project that presents itself and we certainly appreciate her drive…glad she’s one of the Family.

“Had to board for four days. I called to check on her and was given in detail how she did. Picked her up and she was not shaking (which she normally does when we are at vets). I will definitely use them again. Love this group. Very friendly and caring!”
