General Women’s Health

For women who may not want specialized care from an OB/GYN, our family medicine physicians are also expertly trained to care for the many specific needs of women. Whether you choose an OB/GYN or family medicine provider, our care teams help you live a healthy life by providing:

  • Annual well-women exams
  • Stress management and diet & exercise guidance
  • Family planning and birth control

Our providers also have the knowledge to help give guidance for women through menopause. Menopause is known for its challenging symptoms, which is why we develop the right course of treatment for each individual woman.

Specialized Obstetrics Care

Our experienced OB specialists understand the importance of providing the right physical and emotional care during pregnancy, while also ensuring a healthy delivery of your child. Whether you are currently pregnant or planning to become pregnant, we’re here for you. 

According to the American College of Obstetricians and Gynecologists, it is recommended you see an OB/GYN multiple times throughout your pregnancy to ensure both your health and the unborn child's. Your initial visit should be at 6 to 8 weeks in. Then, you should visit your OB/GYN once a month until you're 28 to 30 weeks in; at that point, you should have checkups every two weeks until delivery.

Our experienced OB/GYN doctors can provide you with sonograms, ultrasounds, regular checkups, prenatal advice, preparations for labor, and much more. Then, when it's time for delivery, your OB/GYN can be there by your side to help you through it. After delivery, we offer postnatal care for both you and your new child.
