Internal Medicine provides care for your pet when you and your primary care veterinarian decide to pursue more aggressive diagnostic testing, therapeutic treatments, or a second opinion. Specialists in internal medicine complete post-doctoral residency training which gives them the extensive experience and knowledge with which to diagnose and treat patients with in-depth, difficult, or multiple problems of the nervous system, immune system, gastrointestinal tract, endocrine system, pancreas or spleen. The internists at The Hope Center provide consultation on complex medical conditions as well as offer advanced diagnostics and treatment options including ultrasonography and endoscopy.
