Dr. Mark Tsuchiyose, M.D. graduated from USC School of medicine in 1983 and completed his Internal Medicine residency at Huntington Memorial Hospital. He then completed his fellowship in GI at LAC/USC Medical Center. He returned to Huntington to complete his Hepatology Fellowship.
During his GI Fellowship Dr. Tsuchiyose sought special training in Holland and Japan to be more proficient in ERCP which then provided the skills to be recruited at his current practice.
During his 30 years of practice, Dr. Tsuchiyose has been an Associate Clinical Professor at the University of California, San Francisco. He has been a leader at his primary hospital, Seton Medical Center in Daly City. He served as Section Chief of Gastroenterology, Head of the Nutrition Support Team, Chairman of Medicine. He also served on the board of the Seton Foundation. Dr. Tsuchiyose has always been an advocate for private practice, where physicians have the ability to put their patients first. He served as president of 3 separate physician groups to accomplish this goal.
Dr. Tsuchiyose’s passion now lies in treating the root causes of diseases rather than treating symptoms. This has led him to creating the SMART weight control program combating the epidemic of obesity and the metabolic syndrome. He also has a passion for Functional GI Disorders which requires a relearning of medicine from his traditional education.
Dr. Tsuchiyose 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. He also has recently discovered the magic of Aikido, a Japanese Martial Art that integrates a peaceful philosophy of life.

He was professional and caring
Very attentive and knowledgeable. Excellent bedside manner. Highly recommend!
I waited for over one hour from my appointment time, and the doctor was rushing with my appointment, and took about 5 minutes with me, didn’t clearly explain the new medication.
Very knowledgeable and professional. His explanations were easy to understand
This was my first visit with Dr Tsuchiyose I was very nervous, but he made me feel more comfortable as he explained things to me
Excellent experience. Dr Tsuchiyose is a very up to date and knowledgeable GI specialist.
Proactive and respectful conversation with the patient to discuss treatments or options for their well-being.
Is the best Doctor is the Rated 10
Totally profane thorough. Tops in his field.
He persist on NASH treatment, but I let him know that I use to drink wine on and off for many years. He is not taking care of the diverticulosis just in the right side where I feel pain. He checked my abdomen because of I requested him to do it. He confused me because he said that I have scars, but in a recent velacur US in the office at Sullivan office states cero fibrosis and insignificant steatosis.
