In Chula Vista's Medical Center Drive corridor, Dr. Elmer W. Harder, MD has provided obstetric and gynecological care through South Bay OBGYN Medical Group since 1985, delivering more than 14,000 babies across his career. His prenatal medication protocols — from progesterone supplementation to gestational diabetes management — are dispensed through local pharmacies including South Bay Pharmacy for the corticosteroid, antiemetic, and prenatal vitamin prescriptions central to his obstetric panels. He holds a medical degree from the Universidad Autonoma de Guadalajara, completed a four-year OB/GYN residency at UCLA, and speaks English, Portuguese, and Spanish — serving Chula Vista's multilingual South Bay population. His high-risk obstetrics caseload encompasses placenta previa, intrauterine growth restriction, and gestational hypertension, and the practice integrates postpartum mood-disorder screening with perinatal counseling from Brenda Duarte, Counselor into its follow-up protocol. Highest-complexity surgical procedures include laparoscopic hysterectomy, operative hysteroscopy with endometrial ablation, and emergency cesarean delivery under general anesthesia at Sharp Chula Vista Medical Center.
