Doug Campbell - Veterinary Technician
I joined the staff of Old York Veterinary Hospital in October of 2016. Prior to this I proudly served in the United States Coast Guard for five years as an EMT and a marine diesel technician.
I am honored to be an Eagle Scout. Presently, I am taking classes toward a degree as a Certified Veterinary Technician through Cedar Valley College. I hope to further advance my CVT career through specializing in surgery. In my free time, I enjoy fishing with my Bloodhound, Duke and working on my car or motorcycle.
Megan Zelazny - Veterinary Technician
I joined the Old York Veterinary team in August of 2024. Before joining this team, I attended Brookdale Community College and Kean University graduating in 2017 and 2024. The past seven years of my career have been spent working as a veterinary technician in various practices.
My love for animals led me to Old York Veterinary Hospital. I am excited to provide exclamatory care for clients and patients while continuing to grow and learn in the veterinary field.
When not working, I enjoy going for a run, exploring our community and baking! Nothing makes me happier than coming home to my two cats, Bandit and Evie.
Elizabeth Harvey - Business Manager
I had the opportunity to join the Old York Veterinary Hospital team in November of 2021. My love for animals and veterinary medicine has been a passion of mine since before I can remember. As Dr. Campbell’s daughter I have had the honor of being involved with her journey in various roles. Having spent twelve years serving in the Pittsburgh region as an operations and logistics manager, I am thankful for the new role here at Old York Veterinary Hospital.
When not working, I am spending time with my family and friends. My husband and I can be found doing anything outdoors from hiking and fishing to biking our favorite trails. Our cat Smudges will forever be the baby of our home as we continue to grow our family.
Scott Stone - Receptionist
I joined the Old York Veterinary team in April of 2022. With me I bring many years of experience working in customer service in the banking field. Getting to interact with clients everyday and helping them in any way I can has always been my passion.
Memories made with family pets lead me to Old York Veterinary Hospital. It is my goal to have a positive impact on those joyful memories with the families that I meet each and every day.
When not working you can find me doing anything with sports, especially the Phillies, Notre Dame and the Bengals. My girlfriend and I also care for the most wonderful cat Talon, whom we love dearly.
