Lawrence Flechner, MD, PhD, FACS

lawrence flechner

Dr. Lawrence Flechner originally hails from San Francisco. He graduated Phi Beta Kappa from Stanford University, majoring in History—a passion he pursues to this day—while at the same time completing his premedical studies. He then won a coveted scholarship to spend a year researching molecular mechanisms of Cancer at the National Institutes of Health in Bethesda, Maryland.  Inspired to connect medical research with patient care, he went on to receive MD and PHD degrees at UCSD and The Salk Institute in La Jolla, California. Under the mentorship of the National Academy Sciences Member Marc Montminy at The Salk, Dr. Flechner made significant advances in our fundamental understanding of sugar metabolism and Diabetes. Specifically, he helped characterize a gene that is essential for blood sugar control. This important work made publication in the prestigious journal Nature. Dr. Flechner’s career next took him to top ranked UCSF Department of Urology, a place of historic significance in shaping the practice of Urology. Dr. Flechner trained under the close mentorship of Doctors Jack McAnanich, Peter Carroll, Marshall Stoller, and Tom Lue, each titans in their respective fields of Urology. At UCSF, Dr. Flechner gained extensive experience in the management of all aspects of benign and oncologic Urology, with expertise and versatility in conventional open, laparoscopic, and robotic surgery. After completing his training in 2012, Dr. Flechner was recruited to become a Partner at the Urology Institute of the South Bay. He is married to a successful leader in Education from Los Angeles, and they have two young children. Dr. Flechner is among the busiest robotic surgeons in the South Bay, and serves on the Robotic Surgery Committee at Torrance Memorial Hospital. A compassionate and dedicated surgeon, he serves on the Advisory Board of the Cancer Support Community of Redondo Beach, and on the Manhattan Beach Rotary Club. When not working, he enjoys organizing family adventures around the world, jogging on the Strand, scuba diving, archaeology, and being a present Dad to his growing kids.
