About Dr. Leach OB/GYN
This is a general OB/GYN practice that also delivers babies and does gynecologic surgery, so menopause care sits alongside the rest of women's health. Dr. Leach is also Medical Director of OB/GYN at John Muir Walnut Creek. The office prescribes FDA approved bioidentical estradiol and progesterone by mouth, on the skin or in the vagina. It prefers these to compounded hormones because blood levels can vary from batch to batch. Marybeth Wakefield, a nurse practitioner who also holds the Menopause Society certification, sees midlife patients in the same office. The practice works with the Cancer Support Community of Walnut Creek to help survivors with symptoms like vaginal dryness, including those who cannot use estrogen. New patients are currently being welcomed.
