About Banner Peak Health
Banner Peak Health is a four physician concierge practice in Walnut Creek, and Klein is the one who carries the Menopause Society certification. Care runs on an annual membership that covers unlimited visits and direct access to your own doctor by cell phone at any hour. New members start with a phone call to the practice director, then an unhurried meeting with the physician they would see, then a baseline assessment that can run two hours. Writing about perimenopause, Klein says she rules out thyroid problems, IBS, SIBO and gastroparesis before she looks at hormones, because the symptom cluster gets missed for years while a woman is sent from one specialist to the next. For treatment she describes an estrogen patch with oral progesterone, sometimes a progesterone IUD for endometrial protection, and a small amount of testosterone when it helps. She spent ten years in internal medicine at John Muir Medical Center and left because that setting gave her no time to be present with patients.
