Our Team

Donna Harrison


Hi, I'm Donna! I'm the owner of Crabapple Animal Hospital as of 2001 and I've been working at the hospital since 1986.

I was born in Montvale N.J. and moved to Georgia when I was about 10 years old in 1978 with my 3 siblings and parents. We lived in Sandy Springs and I attended North Springs High School. I went to work full time for Kroger when I graduated and worked also part-time for the original owner of the practice and came on full time in 1989.

I truly love all animals and have had pets of my own that came to this practice. I've always enjoyed the atmosphere here as well as the people. One of my favorite things about working here and with the animals, is that I learn something new every day even after all these years and I very much enjoy the pets and their families.

Even though it sounds super cheesy, I knew the first day I came to work here that this was the job for me. It all just felt so right.

With my husband recent passing, my family now just consists of myself and my daughter, Anna. We've also got what we call "the crew", our pets, Autumn (Anna's dog), O.D. (my dog) ,O.C. (our cat) and Dakota (our bird who is a cockatiel).

Lisa Tanner


Hi, I'm Lisa! I'm a veterinarian here at Crabapple Animal Hospital and I've been working here since 2013.

I was born, grew-up and lived in Wisconsin. I've trained dogs and horses my whole life, but didn't start veterinary practice until I graduated back in 2002. I love seeing the different personalities of the pets and watching the bond each animal has with it's owner.

I earned a BS in biological systems engineering in 1996 University of WI-Madison, then started working towards my DVM in 2002 from University WI SVM. My career began in shelter medicine, then switched to a small animal general practice. I moved to Florida for a few years, then moved to Georgia in 2013 and have been working at Crabapple AH since then.

I enjoy taking my problem-solving and engineering background and applying it living creatures. Being able to help people and animals on a daily basis, with a diversity in what I need to do daily and constantly learning really pushes me to evolve in the practice of medicine.

I'm a member of AVMA and VIN since 2002. I enjoy all aspects of small animal medicine, but have a great interest in surgery and dentistry. Both interests are very challenging, but allow for rapid changes in animals quality of life.

My family consists of my husband Jason and son Malachi. We live on a 10-acre ranch with 5 horses, 15 chickens, 4 dogs and 3 cats. I enjoy training the dogs for obedience, hunt testing, and agility. We occasionally breed our health and behavior tested labradors, and are hoping to compete in some more AKC competitions in the upcoming years.

Anna Harrison

Veterinary Technician

Hi, I'm Anna! I'm a veterinary technician here at Crabapple Animal Hospital.

I was born in Woodstock, but only lived there until I was about a year old. Then we moved to Duluth, where we could be close to my grandma on my dad's side. We lived there until I was around 10, but then we moved to Buford and lived on Lake Lanier. I did online school throughout middle school but then returned to brick and mortar for high school. After I graduated, I went to work full-time for my mom here at the animal hospital. After my dad passed away in April, she and I moved down here to Alpharetta and we now live across the street from the animal hospital.

Growing up with parents who own an animal hospital, I kinda grew up here, so it was second nature for me to be involved in this industry. I've always loved it here as well as working with animals, but when I was younger I don't think I ever really had my head wrapped around it all. As I got older and spent more and more time here and working with everyone, I really understood what it was all about, which in the end only made me love it more. I think my favorite thing about it all is honestly the one-on-one time I spend with the animals.

When I graduated high school, my initial plan was to work full time for a little bit and then pursue a profession by going to college. I first thought I'd be a vet because that made total sense at the time. When I hit one year of working here, full time, I thought to myself that I'd take awhile longer to decide what I really wanted to do considering vet school is sooo expensive and takes so much time. When the second year rolled around after graduating, I realized I hadn't given any thoughts to college and thought a lot about what I'd want to study. And here we are - more than 3 years out from me graduating, finding myself pursuing the family business. When I realized that the last thing I wanted to do was go to college and have my head buried in a book, that I'd rather be here learning hands-on and working toward becoming an amazing business owner like my mom. That's when I knew I was in the right profession.

Leigh Ann Gill

Pet Stylist

Hi, I'm Leigh Ann! I'm a Pet Stylist here at Crabapple Animal Hospital.

I started grooming dogs to help a local animal shelter and was taught more about grooming by a seasoned groomer who saw my potential. The Roswell/ Crabapple area is an amazing part of Georgia and, while I don't currently reside in this area, I did grow up in the area and it always keeps me coming back because of the people and the pets that do reside here.

Ever since I was a young child, I knew I wanted to work with animals. My father still tells stories of when I was in elementary school and would go on and on about how when I grew up, I wanted to work with animals. I didn't know what I wanted to do with them. I just knew I wanted to help. As I grew older, I worked in the kennel as a vet tech, and a receptionist before I finally found my love for grooming and helping animals become more comfortable in their fur.

The day I knew I was in the right profession was the day I groomed a shelter dog that had just been rescued and desperately needed a groom. The dog was completely matted and so very scared. I took my time and went slow and by the end of the groom, not only did the dog look completely different, but was acting completely different. The dog wasn't scared and was jumping on me and giving me kisses as if to say " Thank you, thank you, thank you, I was so uncomfortable and you made me feel so much better!". After that moment, I was hooked and knew this was where I was meant to be in the veterinary field.

Outside of the office, I enjoy being outdoors. I love to kayak, hike, and swim. I also love watching movies with my family and spending time with my 2 dogs Brother Harley, Sky, and my cat Spooky. There is nothing better then coming home and relaxing with my loved ones.
