About Dr. Justin Derosa

Dr. DeRosa is a double board-certified gastroenterologist and is delighted to practice at Advocare Stoll Medical Group where he can serve the digestive health needs of the residents of his community in which he was born, raised, and currently resides with his family. Dr. DeRosa was drawn to medicine from a very young age; he always knew he wanted to be a doctor so that he could help others and knew he had found his calling while completing his residency and GI fellowship at RowanSOM/Jefferson Health. Dr. DeRosa is very dedicated to his field and especially to his patients. His special interests include colorectal cancer prevention, acid reflux disease and fatty liver disease. Dr. DeRosa is a proud graduate of Arcadia University and the Philadelphia College of Osteopathic Medicine, where he met his wife, an internal medicine physician who is also a native of the greater Philadelphia region. On the days he is not working he is kept busy with his wife running around after their active toddler, spending time with family, watching Philly sports, eating good food and relaxing at the Jersey shore.
