Dr. Zenn and his staff were excellent! I had a bilateral mastectomy and he did my reconstruction. I had previous radiation and he suggested a new way to perform surgery to optimize my result. Personally I enjoyed his bedside manner, he was straight to the point, and did not sugarcoat any of the risks. He was very meticulous in his methods and demanded that of his staff. The office at the cancer clinic was very accommodating to my schedule during all of the follow up appointments. I would highly recommend Dr. Zen and staff.
