    BioPelvic floor and functional bowel disorders refer to a series of symptoms and anatomic findings that effect men and women of all ages. These may include: constipation, difficult evacuation, fecal incontinence, irritable bowel disorders, diarrhea, pelvic organ prolapse, urinary and sexual dysfunction and pain. Although not life threatening, these disorders can severely affect quality of life and individual performance.

    Over the past two decades I have dedicated my career to working with other specialists for comprehensive care for individuals with pelvic floor disorders. In July 2017, I joined The Department of Surgery, Division of Colorectal Surgery at Stanford University as the Medical Director of the Pelvic Health Center. I previously spent the prior decade at Cleveland Clinic running a multidisciplinary clinic and performing over 200 combined procedures in conjunction with colleagues in urology and urogynecology. We developed a robotic surgical approach to woman with vaginal and rectal prolapse and performed many surgeries to repair intestinal and rectal fistula (abnormal communications between the intestine and vagina).

    Prior to that I established a Pelvic Floor Center at Maimonides Medical Center received a Jahnigan Career Development Award looking at multicompartment prolapse in elderly women. In addition to performing surgery and teaching throughout my career, I have maintained a commitment to long-term follow up of patients after surgery.
    Although my training and focus is around surgical techniques and solutions for anorectal disorders and pelvic health, I believe that prevention, non-surgical alternatives, diet, exercise, and behavior management are vitally important to patient success.

    One of my many goals is to educate patients, health care providers, and trainees about pelvic floor disorders.
    When I am not at work I enjoy quality time with my three teenagers, dog, friends and I practice yoga.
