Dr. Juan brings deep clinical focus to metabolic and cardiometabolic health, midlife hormone transitions, thyroid physiology, GLP-1 and weight management, gender-affirming hormone therapy, and psychiatric medication management for depression, anxiety, and ADHD. His interest in hormone care deepened when his wife raised questions about menopause years ago, prompting him to rethink what he had been taught in training.

He lives in Longmont with his wife and children, and his wife grew up in the community he now serves.
