OUR COMMITMENT 200 patients. Maximum.
A Different Kind of Primary Care

Because personalized care
starts with staying personal.

OG Health will never have more than 200 patients in our practice. By intentionally keeping our membership limited, Dr. Grenardo has the time to know his patients, understand their health history, and remain accessible when they need him.

Fewer patients means more time, greater accessibility, and genuine continuity of care.

Our
Mission

At OG Health, we deliver concierge-level primary care with the heart of family medicine. Led by Dr. Oswaldo Grenardo — a physician with over 30 years of clinical and executive expertise — our practice keeps patient panels small so you receive unhurried, personalized attention year-round. We offer comprehensive services including chronic disease management, hormone therapy, mental health support, preventive screenings, wellness planning, and weight loss management.

Meet Dr. Grenardo

As a first-generation American raised in Colorado by immigrant parents from Guyana and Poland—both of whom proudly served in the U.S. military—Oswaldo Grenardo, MD, MBA, MSHA, FAAFP, grew up with a deep respect for accountability, service, and cultural diversity. These early influences, coupled with a desire to improve the healthcare experience for underserved individuals, led him to start his own private practice, OG Health, in Greenwood Village, Colorado.

With over 30 years of experience in family medicine and healthcare leadership, Dr. Grenardo brings a unique blend of compassionate, personalized care and executive-level insight to his patients at OG Health, the practice he founded to reflect his vision of whole-person care. He believes great care begins with a genuine relationship—where patients feel seen, heard, and truly known by their physician.
