Brian Leish, MD

"I enjoy providing care for the entire family, from children to seniors," says Dr. Leish. "It is a special treat for me to be able to care for children and watch them grow up and share the experience with their parents and grandparents. I also enjoy geriatric medicine and have had extensive experience working with patients from Laguna Woods.  The fun thing about family medicine is the rich variety of people you get to meet."

Brian Leish, M.D., received his medical degree from the University of California, Los Angeles, School of Medicine. He completed his Family Practice residency at San Bernardino County Medical Center. He has been in practice since 1988 and is board certified in family practice.

Dr. Leish has served as a professor at U.C. Irvine's School of Medicine in the Department of Family Medicine since 1992. A California native, Dr. Leish enjoys nature photography, camping, and spending time with his family.

This physician is a member of MemorialCare Physician Society which drives clinical outcomes and performance for MemorialCare Health System.
