Seth A. Cohen, M.D., is a urologist specializing in complex reconstruction of the pelvic floor, including fistula and pelvic organ prolapse repair.

Dr. Cohen received his medical doctorate and Bachelor of Arts degrees at Northwestern University through the prestigious Honors Program in Medical Education, which allowed for direct matriculation into medical school after three years of undergraduate work. He completed his postgraduate training in California, including an internship in the Department of Surgery at University of California, San Francisco, a residency in urology at University of California, San Diego and a fellowship in Female Pelvic Medicine and Reconstructive Surgery at University of California, Los Angeles.

Dr. Cohen has published in a variety of medical journals on topics including mesh-associated complications, robotic cystectomy and radiation exposure during lithotripsy.
