At AdventHealth Medical Group OB/GYN, we’re passionate about providing comprehensive women’s health services throughout a woman’s life span. Our physicians and midwives specialize in normal and high-risk obstetrics, midwifery care, well-woman care, advanced gynecologic procedures and minimally invasive surgeries.
Our Oviedo office provides a personalized, accessible approach to care, all close to home. We offer additional locations with offices in Orlando, Waterford Lakes and Winter Garden.
We deliver babies at AdventHealth for Women (located in Orlando), which is Central Florida’s newest hospital designed for women. AdventHealth for Women features upgraded rooms, private bathrooms and state-of-the-art technology, along with a high-risk obstetrics inpatient unit and Level IV neonatal intensive care unit (NICU).
Our physicians are board-certified and stay up to date on the latest developments in women’s health care. With a special emphasis on education and training, our team partners with various medical schools to train the next generation of women’s care physicians.

Ashley’s Personalized Birth Experience
When Ashley became pregnant with her second child, she knew she wanted to find a new OB/GYN who would support her wishes for a vaginal birth after C-section (VBAC). When she met our Orlando team, she knew she had found the right place to support her pregnancy journey.
