Peter Macfield, MD, is a board-certified family practice doctor serving patients at Breton Village Pediatrics & Family Medicine in Grand Rapids, Michigan. As a provider of integrative medicine, his aim is to help each patient achieve optimal wellness. 

Dr. Macfield gained much of his medical training and education in Michigan. After earning a medical degree at Chittagong Medical College in Chittagong, Bangladesh, he moved to Grand Rapids to complete a medical residency at Grand Rapids Medical Education & Research Center at Michigan State University. The program was based at Mercy Health St. Mary’s.

Since then, Dr. Macfield has emphasized a holistic approach to family medicine. He maintains a special interest in functional medicine and complementary medicine. 

Dr. Macfield focuses on preventive medicine, hormone replacement therapy, osteoporosis, and the management of chronic conditions, including fibromyalgia, chronic fatigue syndrome, and Crohn’s disease. In addition, he maintains an interest in Fabry disease, a rare genetic condition, and porphyria, a group of disorders caused by a buildup of chemicals in the body.

Dr. Siân West is a board-certified OB-GYN (American Board of Obstetrics and Gynecology), osteopathic physician, and Menopause Society Certified Practitioner (MSCP) who focuses exclusively on perimenopause and menopause care. She completed her OB-GYN residency in Lansing, Michigan, and has spent more than a decade in delivery rooms, operating rooms, and the long-undervalued conversation that is midlife women's health.

She founded The TelePause for women who have been told they're too young, that their labs are normal, or that it's just aging. Her visits are unhurried and built on a thorough history, a clear explanation of what the evidence says, and shared decision-making. She uses FDA-approved, regulated hormones so treatment can be precisely dosed and adjusted, and offers evidence-based non-hormonal options for women who can't take hormones or prefer not to. Her care goes beyond symptom relief to protect long-term health, including sleep, nutrition, and metabolic, bone, and heart health.

Dr. West is also the host of This Meno Life, a weekly podcast that breaks down what the science actually says about perimenopause, menopause, and midlife women's health, in plain language. The show calls out misinformation from both dismissive medical care and the wellness industry, and gives women practical tools to understand their bodies, weigh their options, and advocate for the care they deserve.
