About Advanced OB-GYN Services

Dr. Joseph Hazan, M.D., F.A.C.O.G.

For over 30 years, Dr. Joseph Hazan of Advanced OB-GYN Services has been dedicated to providing professional gynecological care that patients can trust. He and his compassionate team are committed to giving each woman who comes in a personalized, comfortable experience, starting from the moment she walks through the door.

Dr. Hazan is a board-certified OB-GYN who prides himself on seeing his patients as people with real lives, questions, and concerns, not just as a chart of medical notations. That’s why he works hard to ensure that each patient doesn’t spend too long in the waiting room, offers both early morning and evening hours to accommodate all schedules, and takes a personal interest in each and every one of his patients. When you have questions, Dr. Hazan will be there to answer them. He’s also available to support his patients with same-day appointments for emergencies and remains on call 24 hours a day for existing patients.

Dr. Hazan offers a number of cutting-edge services and procedures, including NovaSure®, the safe, painless, and effective 90-second answer to abnormal uterine bleeding. He also provides annual gynecological exams, ultrasounds, infertility counseling and osteoporosis evaluations, and he has delivered over 6,000 babies.

Finally, Dr. Hazan and his team believe that everyone should have access to superior quality gynecological care. He and his staff are committed to making their services affordable to everyone. Not only are you welcome to use your insurance policy to cover the cost of an appointment or procedure, but Dr. Hazan is happy to work out an individual payment plan with you when other options aren’t available.

For experience you can trust, schedule an appointment with Dr. Hazan and the team at Advanced OB-GYN Services. They offer two locations to better service your needs. Call (636) 928-1800 for the St. Peters, MO office, or (314) 291-2140 for the St. Louis, MO, office today.

"I loved Dr. Hazan and his nurses so much! He took excellent care of me during my pregnancy and delivered my baby boy amazingly. I was provided with the best care and he always answered all my questions and gave me so much peace of mind. Also, he let my boyfriend be a part of every appointment which I am super grateful for. He’s really the best. ☺️"... more
