Internal Medicine

Internal Medicine is a specialty dedicated to the diagnosis and treatment of chronic and complex diseases affecting the liver, kidneys, lungs, gastrointestinal tract, pancreas, immune system and endocrine organs. Internal Medicine specialists undergo a multi-year, rigorous training program following veterinary school and must pass an intensive certification exam. In addition, they are also required to publish a research paper in a peer reviewed journal in order to obtain Board certification.

Internal medicine specialists have expertise in tailoring diagnostic plans to each individual patient to determine a diagnosis in a timely and cost efficient manner. They are highly trained in treating critically ill animals and patients with multiple complex problems. In addition, they are proficient in minimally invasive procedures including rhinoscopy (nose); gastroduodenoscopy (stomach and upper small intestine); colonoscopy (large intestine); cystoscopy (urinary bladder); bronchoscopy (lungs); and, laparoscopy (liver).

Our Internal Medicine department is fully equipped with multiple flexible and rigid endoscopes to provide a full range of capabilities. Additionally, our new, state-of-the-art ultrasound machine gives us the capability to provide emergency and diagnostic ultrasounds when our Radiology team is unavailable.

Our Team
