The American Association of Gynecologic Laparoscopy recognized her in 2017 as a founding surgeon at The California Pacific Medical Center Minimally Invasive Gynecology Center of Excellence due to her laparoscopic and robotic laparoscopic volume and outcomes. Because of her history of performing trans-masculine laparoscopic & robotic hysterectomies, as well as cis-gender vaginoplasties, Dr. Wittenberg was recruited to train further with an intensive fellowship with reconstructive plastics surgeons and reconstructive urologists to perform gender affirmation surgeries of vaginoplasties and full metoidioplasties. Since her additional training, she now focuses 100% on gender affirmation surgery. Currently, she is the Director of MoZaic Care Inc, Co-Director of the first Center of Excellence Gender Confirmation Surgery Center at Greenbrae Surgery Center as of 1/2019, and appointed a Master Surgeon of Excellence in Minimally Invasive Gynecology 6/2019. This designation is granted from a non-profit, patient safety organization that looks at volume, complications and outcomes- the Surgical Review Corporation.
in 2021, Dr Wittenberg became the Medial Director of the Gender Institute at Saint Francis Memorial Hospital, the Chief of Surgery there too and was the founding surgeon & director for the first national and international hospital to be designated Center of Excellence in Gender Affirmation Surgery is Saint Francis Memorial Hospital.
While newer locations are cobbling together teams for surgery, due to her extensive background in pelvic reconstructive surgery, experience, and training, Dr Wittenberg is the surgeon for every portion of the procedures offered.
