I recommend this veterinary hospital because it is the most thorough in the Delaware County, PA region. Expensive but worth it. I was an employee there for roughly 6 months and saw first hand the quality treatment of their client's pets. I was impressed with every care and pre-caution they took to make sure the animal's health was well cared for. They specialize not only in regular animal health, but also have a surgery hospital as well as 8 veterinarians on staff in addition to boarding facilities.
PROS: Surgery, Boarding options
CONS: Very professional - can come across as impersonal.
