Internal Medicine, DVM, DACVIM

About Me

Dr. John DeBiasio, a native of Bergen County, New Jersey, fell in love with the Philadelphia area after attending the University of Pennsylvania where he graduated summa cum laude with distinction in Biology, earning his Bachelor of Arts in Molecular and Cell Biology in 1999. He continued his education at Cornell University, College of Veterinary Medicine, where he was awarded his Doctorate in Veterinary Medicine in 2003. After graduating, he completed a rigorous one-year rotating internship in Small Animal Medicine and Surgery at Oradell Animal Hospital in Paramus, New Jersey. Following his internship, he accepted a faculty position at Texas A&M University, College of Veterinary Medicine, teaching fourth year veterinary students on the Community Practice Service. He then went on to enter a three-year, Small Animal Internal Medicine Residency program at Texas A&M. Upon completion in 2008, he obtained his board certification from the American College of Veterinary Internal Medicine.

Dr. DeBiasio has been with MVA since 2008 and is currently the Hospital Medical Director.  His clinical interests within the broad discipline of internal medicine include gastroenterology (with a particular focus on endoscopy), hepatology, hematology, respiratory disease, endocrinology and infectious disease.

Dr. DeBiasio performs numerous specialized procedures which include, but are not limited to, laparoscopic surgery, gastroduodenoscopy, colonoscopy, rhinoscopy, bronchoscopy, urethrocystoscopy, radiographic contrast studies, feeding tube placement (PEG, esophagostomy, jejunostomy), bronchoalveolar lavage, tracheal stenting, urethral synthetic collagen bulking (for urinary incontinence), and bone marrow aspirates and biopsies.

In his free time, Dr. DeBiasio enjoys running, caring for his menagerie (two dogs, two cats, snakes, geckos, frogs, and chickens), and most of all spending time with his wife, and two daughters.
