Internal Medicine


What is an internist?

Internists, or internal medicine specialists, are experts in the diagnosis and treatment of conditions that affect the vital organs. That includes the respiratory system, digestive system, liver and pancreas, endocrine system, urinary system, and immune system as well as infectious diseases, among others. Your veterinarian would refer your pet to us because they might need specialized expertise.
