Founded in 1993, Glenmoore Veterinary Hospital has long been a center for premium veterinary care in Chester County. As one of the few American Animal Hospital Association (AAHA) certified clinics in Southeastern Pennsylvania, we pride ourselves on our commitment to excellence in veterinary medicine. We are a full-service hospital offering state-of-the-art in-house diagnostics, with the ability to perform small animal surgeries, dental procedures, and much more.

Over the years, we have expanded our services and facility to meet the ever-changing demands of the veterinary field. We are open six days a week, Monday through Friday from 7:30 am until 7:00 pm, and on Saturday from 8:00 am until 12:00 pm to help better serve our clients and animal friends. Although we will gladly accommodate daytime emergencies, we highly recommend scheduling an appointment to avoid a wait. Our receptionists will do their best to get your pet seen in a timely manner.

Our doctors, Gregory Tremoglie, Joshua Roesener, Neil Van Tilburg, Emily Rudner, and Sarah Pritchett are joined by an experienced and friendly staff of Certified Veterinary Technicians, veterinary assistants, and receptionists.

Here at Glenmoore Veterinary Hospital we strongly believe in preventative medicine. We feel that regular wellness exams, parasite prevention, and health screening lab work are an important part of managing your loved one’s health and helping to make sure that he or she is around for many years to come. Since your animal friends cannot talk, we rely upon regular check-ups to catch subtle changes in their health before problems occur.

Our mission is to provide them with the quality, loving care that we would want for our own pets, throughout their life. We will continually strive to provide you with the compassion, respect, and quality care that your family member deserves. We will do our best to make you feel at home, providing an environment that is comfortable and welcoming to the entire family.

As a matter of fact, we are a certified Cat Friendly Practice and we are proud to provide our feline patients alternative methods to reduce stress during their visits.

If you ever have any questions regarding your pet’s health, diet, behavior, or general care, please do not hesitate to contact us. We also appreciate your comments, suggestions, feedback, and even referrals.
