Chang is committed to ensuring that all patients have access to high-quality treatment for pelvic organ prolapse, urinary issues and congenital or acquired conditions that require vaginal reconstruction.

Chang also provides gender-affirming surgeries for transgender patients, including gender-affirming hysterectomy, bilateral salpingo-oophorectomy, vaginectomy, revision vaginoplasties and complex vaginal reconstruction with the use of myocutaneous (skin/muscle) flaps.
