I am an endocrinologist with particular interests in reproductive and bone health. I enjoy treating patients with menstrual disorders, menopause, fractures, osteoporosis, parathyroid imbalance, and calcium imbalance. As a certified menopause practitioner (North American Menopause Society), I help women fine-tune their health at the mid-life transition. Some women transition through menopause with ease, while others experience challenging symptoms like hot flashes, slowed metabolism, and mood changes. This transition period provides a good opportunity to create a "game plan" for preserving future health. It also marks the beginning of natural bone loss, leaving one more susceptible to fragility fractures.

Dr. Marco Perez's research goal is to better understand the fundamental causes of cardiovascular disease through the study of genetics and epidemiology. His group studies the genetic variations and environmental exposures that are associated with conditions such as atrial fibrillation and heart failure. He has led the studies of atrial fibrillation in Women's Health Initiative, one of the largest nation-wide population-based cohorts. He is currently conducting a large study monitoring for silent or asymptomatic atrial fibrillation in women from the WHI randomized to exercise intervention, and was co-PI of the Apple Heart Study, a clinical trial that validated the ability of a smartwatch to detect atrial fibrillation.
