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.
