Kind words from our patients

Real reviews from real patients.

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.

Our Services

Medical Weight Loss

Weight rarely moves on its own. Thyroid function, blood sugar, blood pressure, sleep, and the medications you already take all play a role. At OG Health, a physician directs your weight loss plan using labs and your full health history, not a one-size-fits-all template.
Our physician-guided medical weight loss in Greenwood includes semaglutide and other GLP-1 treatments, weight loss injections, prescription weight loss medication, obesity treatment, metabolic assessment, and nutrition counseling. A weight loss consultation is the first step, and weight management continues after you reach your goal.

General Practitioner

Conditions like diabetes and high blood pressure don't go away on their own, so they need a doctor who keeps watching them. At OG Health, Dr. Grenardo manages diabetes, high blood pressure, high cholesterol, thyroid disorders, asthma, and arthritis over time, adjusting your plan as your numbers and your life change.
With general practitioner care in Greenwood, your own doctor can also help with anxiety, depression, and mental health counseling check-ins, and can treat sudden problems like urinary tract infections. You get one physician who sees the whole picture instead of a new face at every visit.

Medical Center

A visit to the OG Health medical center starts with the full picture: a comprehensive health evaluation, followed by a personalized plan that turns your results into next steps. Advanced lab testing and precision testing are chosen around your specific risk, not a standard panel.
Our medical center services in Greenwood Village also cover longevity medicine, lifestyle medicine, care coordination with your specialists, medication reconciliation, transitional care after a hospital stay, and hospital care support, so someone is in your corner when your care crosses offices.

Medical Clinic

When you want answers about your health, OG Health offers blood work and lab testing, along with screenings for diabetes, cholesterol, and thyroid problems. Catching changes early, and tracking them over the years, is how small issues stay small.
Our medical clinic in Greenwood also include EKG testing, strep throat testing, sinus infection treatment, a private STD testing consultation, and an allergy testing consultation, with a physician you can talk to about what your results mean.

Medical Office

OG Health's medical office offers hormone replacement therapy, testosterone therapy, bioidentical hormone therapy, and peptide therapy, with a physician explaining what each one is, who it's for, and what to expect.
The same medical office in Greenwood Village provides executive physicals, preoperative clearance, sleep disorder evaluation, travel medicine consultations, travel vaccinations, and behavioral health services as part of your primary care.

Our goal is for you to leave our office with a memorable and enjoyable experience, which is why our welcoming and compassionate staff will do everything they can to make you feel right at home.
