Dr. Biswell earned his DVM and completed an anatomic pathology residency from Purdue University. After becoming board certified by the American College of Veterinary Pathologists he took a job at ZNLabs (now Zoetis Reference Labs). In this position he specialized in neuropathology and zoo/exotic pathology, and had the great honor to work closely with the legendary Dr. Drury Reavill. He has also traveled the world (Brazil, Austria, Japan, and France) learning veterinary medicine/pathology from these regions. All this gave him the experience necessary to start his own veterinary diagnostic lab, Biosphere Lab.
