Board-certified in obstetrics and gynecology, Lisa Ann Johnston, MD brings Chula Vista's Eastlake corridor a high-risk pregnancy practice rooted in a 1994 University of Western Ontario medical degree and a Surgeon of Excellence in Robotic Surgery designation from the Surgical Review Corporation. Her scope of postpartum rehabilitation referrals extends into the same Otay Ranch medical network that includes Performance Plus Physical Therapy's pelvic-floor recovery program. As a Sharp-affiliated provider, she operates through Sharp Chula Vista Medical Center's labor and delivery unit on the Medical Center Drive healthcare corridor. The practice integrates perinatal mood disorder screening into its obstetric workflow, coordinating behavioral health pathways with Stars Therapy Services for patients across the postpartum spectrum. Highest-complexity procedures include robotic-assisted laparoscopic hysterectomy, myomectomy for uterine fibroids exceeding 10 cm, and multi-organ endometriosis excision.
