Brian Juan, MD

Dr. Brian Juan is a board-certified family physician and the founder of Metronome Family Medicine. He practices full-scope family medicine with particular attention to perimenopause, menopause, and andropause, hormone and thyroid care, metabolic health, and longevity medicine — always treating each patient as an individual rather than a protocol. His background reflects a deep commitment to both patient care and medical education: he is a recipient of the Golden Stethoscope Award for Excellence in Medical Education, currently serves as Clinical Liaison for Family Medicine in the University of Colorado School of Medicine's Longitudinal Integrated Curriculum, and was a Department Technical Lead in Medical Informatics at Kaiser Permanente. A lifelong professional musician, he built Metronome to practice medicine the way it should be: with time, direct access, and a genuine relationship at the center. He welcomes patients who want a doctor who knows them well and will take the time to listen.

Metronome Family Medicine is a Direct Primary Care practice in Longmont, Colorado, offering full-scope family medicine for individuals, families, and employer teams — plus telehealth across Colorado. Membership means direct access to your physician by phone, text, and email; same- and next-day visits; and unhurried appointments with time to actually get to the root of things. Alongside comprehensive primary care, the practice offers a special focus on midlife vitality — hormone optimization, thyroid and metabolic health, GLP-1 and weight management, and longevity-focused prevention — bringing care that's often scattered across multiple clinics under one roof. An on-site pharmacy passes wholesale medication savings directly to members.
