Mitchell L. Cohen, MD, AGAF, FACG
Dr. Cohen was born and raised in Los Angeles, California before attending the University of California, Los Angeles (UCLA) where he graduated Phi Beta Kappa in 1976 with Special Honors in Chemistry and Biochemistry. While at UCLA, Dr. Cohen spent his junior year abroad as a Foreign Exchange Student at the University of Stirling in Stirling, Scotland in the United Kingdom. He received his Doctor of Medicine degree from the University of Southern California School of Medicine (USC) in 1981. He moved to the San Francisco Bay Area where he completed an Internship and Residency in Internal Medicine at Santa Clara Valley Medical Center which is the Stanford University-affiliated County Teaching Hospital located in San Jose, California. Following this, Dr. Cohen completed a Clinical Gastroenterology Fellowship at the University of New Mexico in Albuquerque, New Mexico. With a strong interest in academic medicine and research, Dr. Cohen subsequently spent nearly five years at Stanford University School of Medicine in Stanford, California. There, he carried out research on the molecular regulation of small intestinal brush border enzymes. He was awarded a Clinical Investigator Award by the National Institutes of Health in Bethesda, Maryland. While at Stanford, Dr. Cohen also held a Clinical Faculty position teaching medical students, Internal Medicine Residents and Gastroenterology Fellows.
In late 1991, Dr. Cohen’s focus turned to private practice medicine. He joined a private practice multispecialty group at Swedish Medical Center in Seattle, Washington. Dr. Cohen served on many hospital committees and eventually became Chief of Gastroenterology for Swedish Medical Center. While practicing in Seattle, he was named by peers and independent research as a Seattle Super Doctor and was voted by peers as one of Seattle’s Top Physicians in Seattle Magazine.
In 2014, Dr. Cohen left practice at Swedish Hospital (though remains Honorary Staff) and joined a private practice group in Central Washington, building a very successful Gastroenterology program in Moses Lake, Washington.
Eager to return to Western Washington, to be closer to his home in Sammamish, Washington, Dr. Cohen now joins Summit Pacific Medical Center as both Gastroenterology and Endoscopy Medical Director, tasked with building a new Gastroenterology program, and as a practicing gastroenterologist.
