Jennifer Cohen, DVM

Dr. Cohen is a California native who graduated from UC Berkeley and has traveled the world serving in Paraguay as a Peace Corps Volunteer to finishing her DVM degree in the Caribbean from Ross University. She has a deep love of zoo, wildlife and exotic medicine which stems from her short time in wildlife rehab and zoo-keeping. She loves her friends and family including her two pups, Bourbon and Goose, and is excited to continue caring for all creatures at Munhall Vet.

Maria Gorka, VMD

Dr. Maria Gorka joined Munhall Veterinary Hospital in 2021. Dr. Gorka graduated from the University of Pennsylvania veterinary school and has previously worked as a veterinarian in a mixed animal practice and a high volume spay and neuter clinic. She was born in Johnstown, Pennsylvania and completed her bachelor’s degree in Nutritional Biochemistry from Case Western Reserve University. In her spare time, Dr. Gorka enjoys hiking, traveling, and visiting national parks.

John Stoner, DVM

Dr. Stoner graduated from Vet school at Cornell University in 1985. He recently purchased Munhall Veterinary Hospital and plans to practice there on a limited basis, primarily working in an advisory role for the younger practitioners. Dr. Stoner owned and operated three animal hospitals for 25 years in Central Pennsylvania but sold his interest in them in late 2015.

Realizing he missed the challenges and rewards of practice ownership and mentoring younger practitioners, Dr. Stoner decided to purchase the Munhall practice from Ron Bezak in May 2016. Still residing in Central Pennsylvania with his wife, 20 cows, 2 chickens, 2 dogs and a cat, he makes frequent visits to the Pittsburgh area to work at the hospital and visit with his son, daughter-in-law and grandson.
