Andrew C. Sloyer, DVM

Hello, I am Dr. Andrew Sloyer. After graduating from Franklin and Marshall and the University of Tennessee College of Veterinary Medicine, I practiced in Gilbertsville, PA. I started at Neffsville Veterinary Clinic in May 2000.

I see patients on a daily basis and have special interests and additional training in dermatology and orthopedic surgery.

I lead our team in orthopedic surgery. We do the tibial tuberosity advancement for dogs with anterior cruciate ligament disease, especially dogs over 60 pounds.

We are seeing excellent results with dogs returning to normal function more quickly.

We continue to perform the lateral suture technique for small and medium dogs for repair of ruptured anterior cruciate ligament.

When I am not helping our patients, my wife Kristina and our two sons, Clark and William enjoy spending time on our family farm.

We have two terriers (Isabelle and Winston) and two cats, Franklin and Marvin.
