About Good Hope Animal Hospital

Best Veterinarian Awards from Harrisburg Magazine, The Sentinel, Central Penn Parent, Susquehanna Style, and Angie's List


At Good Hope Animal Hospital, our mission has always been about caring for our clients’ pets like they were our own.


From routine check-ups and preventative care to careful diagnoses of issues and diseases, we work diligently to care for our four-legged friends.  And we take extra steps along the way to ensure their comfort.  Like providing warm, soft beds for recovery after surgery.  Why?  Because the little things matter.  It’s what we want for our own pets.


Our love for animals is also why we get involved in the community and volunteer our time and energy to animal-related causes.  We team up with incredible organizations like CPAA (Central PA Animal Alliance), CHAR (Compassionate Hearts Animal Rescue), PAWS, Furry Friends Network, Castaway Critters, and others. We help by administering microchips, vaccines, and even spay and neuter clinics. In addition, we regularly help these organizations care for the animals they rescue.


We also care about our two-legged clients.  We take the time to talk with you about your pet’s health, answer your questions, and ensure that you know what you need to know to keep your pet healthy and happy.  When your pet needs help beyond routine vaccinations and check-ups, we carefully explain all available options and let you choose the course of action that is right for you and your pet.


At Good Hope Animal Hospital, we endeavor to be more than just a typical vet clinic.  We love our patients, value our clients, and strive for excellence in all we do. Because at the end of the day, we measure our success not by how many awards we’ve won or the number of patients we’ve served, but by how well we’ve served our friends.
