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.

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.

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.

“The attention and service provided to my two dogs by the vet technician (Ms. Wilder) and the Vet (Dr. McDonald) were impressive. They really put my two dogs first and made me feel they care about the health of my pets.”

Jonathan D.

“We just put our three-year-old through training at day camp at Kennesaw Mountain Animal Hospital. Cheyenne and Will are great and Serena’s improved so much that we have taken her to Marietta Market, baseball games for the grandkids, and other little outings.”

“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!”

Freda B.

“If you need a cat groomer, I recommend Marissa! She was patient with my baby Oliver and made him feel comfortable. And he looks great!!!!”
