He has 25 years of experience in the private practice of Gastroenterology. Despite a full career in private practice, Dr. Kramer joined the voluntary teaching staff in the Division of Gastroenterology at Santa Clara Valley Medical Center and Stanford Medical Center in 1978, to help educate house staff and fight tirelessly as a patient advocate for the underserved.
