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 made her way to us and began life at KMAH as Client Services Manager. Ultimately, it led to her current role as Practice Administrator, a position Hannah has always considered a dream job due to her knowledge, compassion, and love for small animals. She is now very content with cultivating a rapport with both clients and their pets while watching our young patients grow into mature companions.

Hannah and her long-time partner, Brent, live in Powder Springs and are parents to a rambunctious English Bulldog, Peanut, who strives to be the best social butterfly he can be. As she is a huge Patriots fan, football season is like a four-month holiday for her. Aside from football, she and Brent enjoy traveling and going to concerts. We are so glad that Hannah and her compassion for animal care have found their way to us.

Theresa Munn
Theresa MunnPet Facilities Manager
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 there 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. The first two years were dedicated to Client Services for our Pet Resort. After two years, Theresa was promoted to Pet Facilities Manager, where she now thrives with the challenges and gratification of pet care. A native of Mableton, she and her partner, Matthew, reside in Kennesaw and are proud pet parent of four rescues: Spock, a young mix that looks like a miniature Rottweiler/Dachsund (her “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 love 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.

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 six months as a 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 a senior, boxer/greyhound mix named, Cody who loves his walks. Life away from the hospital consists of her boy Cody, 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, share their lives with three cats named Cooper, Weibe, and Phaecyt, as well as, a sweet high-spirited canine named, Tag. They also have a bird, Inky.

Outside of work, Jeremy is an avid Star Wars fan and considers the release date of any new movie in the series an important holiday. He’s also fond of Dungeons & Dragons and other nerdy hobbies.

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. This is evident by the number of rescues and fosters that she has opened her home to. With five 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, as is apparent, 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.

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.

Blake Tarnoff
Blake TarnoffKennel Manager
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.

Janel Steinke
Janel SteinkeKennel Assistant
Originally from Southern California, Janel and her family are life-long animal lovers who have never known life without a dog or a cat. When she was seven, her parents brought home a cocker spaniel to lift her spirits after breaking her leg and recovering in a full-body cast for months. Pepper stayed by her side and solidified Janel’s love for dogs. Her pet care career began by attending a pet-grooming school. Upon completion, she began working with a small veterinary practice in North Georgia.

Eventually, she landed at KMAH where she enjoys caring for animals and interacting with our clients. Janel takes great pride in being entrusted to care for our client’s pets.

She’s currently raising her pre-teen daughter and has continued the family tradition of having a pet for her daughter to bond with. Pixiedust Flutters is a sweet rescue mutt and has become her daughter’s best friend. Janel is an avid reader and loves to bake; every Christmas she bakes over 200 cookies for family and friends. With a silly sense of humor, Janel fits in well here at KMAH, and we’re happy to have her part of our family.

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.

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. Aside from her interests in the world of animal care, Robin is a big horror movie fan and loves watching her favorite flicks with the whole family. 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 McTyreTrainer
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.

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, but she didn’t stop there. In 2019 she became a veterinary assistant and has continued to excel at compassionate care for our patients.

Danyell enjoys hiking in the great outdoors, swimming, and spending time with her pets at home. With a love for rescues, she is the mother to three sweet rescues; two canines, Annie and Carmella, and a cat, Nismo. Her compassion for all animals makes her the perfect fit for our team.

Lisa Kruse
Lisa KruseVeterinary Assistant
Lisa is a native of Marietta and has adored the company of animals for as long as she can remember. 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 a kennel technician for two years, Lisa was appointed Kennel Manager for the Pet Resort when our new facility opened. After two years, she moved to Veterinary Assistant, where she now has direct involvement with our patients’ medical health.

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 are parents to a Sphynx-mix (naked cat) named Paxton. She also maintains feedings for a “herd” of strays that frequent their property. We can’t think of a better fit for our medical team and are so pleased to have Lisa’s compassion and skills to care for our patients.

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.

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.

“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!”
