Dr. Jocelyn Hollway, DVM

Veterinarian/Owner

Dr. Hollway is a York County native and realized her love for animals at a very early age. Growing up on a farm surrounded by horses, dogs and cats, it was easy to recognize her passion for the field of veterinary medicine.

Dr. Hollway attended Ross University School of Veterinary Medicine in St. Kitts and completed her clinical year at Kansas State University.

Upon graduation from veterinary school, she started her career at an emergency hospital outside of Philadelphia where she worked for two years. After giving birth to her beautiful daughter, she and her husband decided to return to York to be closer to family.

Dr. Hollway has 2 dogs, Godiva a “coconut retriever” from St. Kitts, and Jamie a rescue from the SPCA. She also has 5 cats; Louie, who has saved many lives of his own as a feline blood donor at Kansas State University; Fendi, a long haired purr-machine and lap-warmer; Vanilla Bean, a rescue who melted her heart when a client found her outside; Mya, affectionately known as “My-My” by her daughter; and lastly, our newest addition, a cat who thinks 3 legs is all you really need, Hiccup.

Jessica McKenzie

Veterinary Technician – Manager
Born and raised on a small farm in Seven Valleys, Pennsylvania, I’ve spent most of my life around and caring for animals. I always knew I would devote myself to a lifelong career in caring for them. I graduated from Spring Grove High School in 2013. Soon after I began attending York County Career Institute, where I graduated with an Associate’s Degree in 2015. I started my Veterinary Technician career four years ago at Seven Valleys Veterinary Hospital; and consider the patients, clients, and fellow employees to be family.

My furry family consists of 2 dogs, Dio and Franco. Four cats, Sammy, Bella, Scraggles, and Smokey. Two Donkeys, Hershey and Donkey, one goat named Violet, and many chickens.

Mollie Durcho

Veterinary Assistant

As a child, I had a great love for animals and as I continued to grow, my passion to help and care for them grew as well. In January of 2019 I began my journey to become a Certified Veterinary Technician by attending YTI Career Institute. This exciting adventure has allowed me to combine my love of science and my passion for helping animals and their families!

My furry babies include Daisy, a Bernese Mountain Dog, Cooper, an Australian Shepherd, and Montana a mixed breed rescue. In my free time I enjoy walking my dogs, reading, and spending time with my family.

Jon Evans

Practice Manager

Jon is a relatively new resident to York County, but is loving it here! Upon graduating from Delaware Valley University in 2014, he has worked in numerous management positions in various industries. He has always had a love of animals, which is what drew him to Seven Valleys Veterinary Hospital.

He has an ever-expanding fur baby family which includes all rescues! His first rescue was a dog named Latona which came from Philadelphia, and the newest addition is Crash a 3 legged cat that he rescued after he was hit by a car.
