Michael A. Werner, M.D., is the founder and Medical Director of Maze Cord Blood Laboratories and its parent company, Maze Health. Started in 1994, Maze Health also includes Maze Laboratories, Maze Men’s Health and Maze Women’s Health.

As part of his infertility practice, Dr. Werner felt compelled to start a semen analysis laboratory, as there were no local laboratories doing a sophisticated analysis on which he could make good clinical decisions.  Subsequently, in 1999, his lab began cryopreserving and storing sperm, for men who would be undergoing treatments that could make them sterile. 

With his passion for helping create and sustain healthy families, and the personal experience of his family losing a son to cancer who may have been cured by cord blood, the decision to create a cord blood and tissue bank that was both superb and affordable, became almost inevitable.

Dr. Werner is a board-certified urologist who received his specialized fellowship training in male infertility and surgery and sexual dysfunction at Boston University Medical Center. He lectures and writes extensively on these topics in medical journals and books. He is also on the faculty of New York Medical College and the Einstein College of Medicine. Dr. Werner completed his Urology residency at Mount Sinai Medical Center in Manhattan and received his medical school training at the University of California at San Francisco. He holds an undergraduate honors degree in Biology from Harvard College.
