About Dr. Mark Tsuchiyose

Dr. Mark Tsuchiyose graduated from USC School of Medicine in 1983 and completed his Internal Medicine residency at Huntington Memorial Hospital in Pasadena, California. He then completed his Gastroenterology fellowship at LAC/USC Medical Center and returned for his Hepatology fellowship at Huntington.

Due to his special training in Holland and Japan, Dr. Tsuchiyose was recruited to his current practice to provide ERCP services in 1989.

During his 25 years of practice, Dr. Tsuchiyose has been an associate clinical professor at the University of California, San Francisco, a Section Chief in the division of Gastroenterology at Seton Medical Center, and Chairman of Medicine over the last four years. He has always been an advocate for private practice and has been president of several IPAs. He is now one of the leaders bringing the SCGA GI model for private practice up to Northern California.

Dr. Tsuchiyose’s philosophy towards medicine is very simple. The patient always comes first. His sole purpose is to use his training and 25 years of accumulated gastrointestinal experience to help patients. This knowledge has been honed by constantly updating his knowledge-base with modern advancements in the field and also by expanding it with the use of alternative strategies not learned in medical school.

He strongly believes in a balanced approach to life. If you do not see him in the clinic or hospital, you will find him on the golf course, tennis or squash court, ski slope, or somewhere around the world with his family. He also enjoys trying new and international dishes from his travels, as well as in the Bay Area. He can confidently say that he enjoys life and the ability to improve people’s gastrointestinal problems, so they can do the same.
