The dedicated Physician Assistants, Mavis Jamal and Denise Verni, work alongside him, assisting Optimal Bio in crafting personalized treatment plans tailored to the unique needs of each patient.

Our dedicated team of doctors and professionals know that every woman will require treatment unique to her exact needs as her body transitions in its hormone changes. That’s why we will take time to listen to your concerns before we begin any hormone testing in Cary, so we can recommend the best hormone treatment, wellness plan, or recommended supplements for your specific concern.

Some of the most common symptoms that we’re able to treat with Bioidentical Hormone Replacement Therapy (BHRT) include depression, fatigue, anxiety, decreased sex drive, mood swings, vaginal dryness, weight gain, memory loss and forgetfulness, poor concentration, arthritis, and other issues related to imbalanced hormones.
