Dr. Jocelyn Hollway, DVM


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.

Dr. Meg Oberer, DVM


Dr. Meg is from Frederick, MD, but is excited to lay down roots in Pennsylvania. In 2017, She earned her bachelor’s degree in Biology from York College of Pennsylvania. During her time at York, she met her fiancé and the pair knew they would make their way back to Pennsylvania after Dr. Meg finished veterinary school.

Dr. Meg earned her doctorate in veterinary medicine from Virginia-Maryland College of Veterinary Medicine (Virginia Tech) in May 2022. While she is a new grad, she is no stranger to the world of veterinary medicine. She started working for a small animal veterinarian as a kennel attendant when she was 16 and has worked as a veterinary assistant and receptionist as well. Dr. Meg knows first hand that our pets are our family and is passionate about caring for your family with love and respect.

In her personal life, Dr. Meg has had ample family pets including dogs, cats, guinea pigs, rabbits, hamsters, and fish. Currently, Dr. Meg and her fiancé have just two pets: a pit bull named Lucy and tabby cat named Fred. Of the small critters, guinea pigs hold a very special place in her heart. It’s her dream to one day own property with chickens and bees. In her free time, Dr. Meg loves spending time outdoors hiking and camping. She can be found attending concerts for her favorite rock bands and tasting the beer at a local brewery.
