Our Doctors

Dedicated fertility doctors

The award winning physicians at Dallas IVF have dedicated their professional careers to helping their patients become parents. Our five expert physicians are all double board certified in reproductive endocrinology and infertility (REI) and in obstetrics and gynecology (Ob-Gyn). Our physicians are members of the Society for Reproductive Endocrinology and Infertility.

Our family devoted to yours

Each Dallas IVF fertility doctor develops a relationship based on trust and expert care with each of her or his patients. We understand the stressful nature of fertility treatments. Many of our physicians have needed fertility treatments to start their own families or to preserve their fertility. Their own personal experiences add an additional level of empathy and compassion to patient care.

Reproductive endocrinologist training

Each of our physicians uses his or her advanced training as an REI to create an evidence-based, custom treatment plan for each patient. This kind of unique expertise only comes from being fully versed in the most advanced techniques and clinical best practices required by REI credentials.

To become a reproductive endocrinologist, physicians must first complete four years of medical school and then a 4-year obstetrics and gynecology residency. Then the physician will spend three years in a fellowship working with other fertility specialists, doing advanced research and focusing on assisted reproductive technologies that continue to evolve in the field of fertility.
