Clinical Sciences & Advanced Medicine

Unfettered knowledge, relentless collaboration, cutting-edge kindness

The Department of Clinical Sciences & Advanced Medicine plays a vital role in Penn Vet's three-part mission to educate veterinarians and the public about animal health, provide service to the public by treating sick pets and other small animals, and develop new approaches through research to improve companion animal health.

  • Teaching

    Fourth-year students rotate through busy clinics staffed by Board-certified specialists in internal medicine, surgery, dermatology, special species, critical care, anesthesia, dentistry, radiology, neurology, cardiology, and oncology. The department also trains graduate veterinarians to become specialists and provides continuing education to veterinarians and the public through programs, seminars, and publications.

  • Service

    The Matthew J. Ryan Veterinary Hospital is staffed by department faculty and staff, who see more than 34,000 patients per year.

    The Ryan Veterinary Hospital is an established world leader in programs such as advanced urinary care, behavior medicine, cardiology, oncology, critical care, internal medicine and surgery.

    Many veterinary specialties now practiced internationally were initiated at Penn Vet. Innovative new programs for treating companion animal patients at the hospital include kidney transplant, a special-species program, animal behavior and nutrition.

    In addition, the hospital has the world's only animal bloodmobile. The interdisciplinary Center for the Interaction of Animals and Society, which studies the social, behavioral, and cultural interactions between animals and humans, is also based in the department.
