It’s About Biology, Not Willpower. And I’m Here to Help.

If you have felt frustrated by yo-yo diets or constant “food noise,” you are not alone. As a dedicated weight loss doctor serving Denver, Centennial, and Highlands Ranch, my life’s work has been proving that obesity is a complex disease driven by biology, not a lack of character.

I am a double board-certified specialist in Obesity Medicine and Family Medicine. Unlike online-only subscription services, my practice in Greenwood Village offers personalized, face-to-face medical care. My team and I look at the whole picture—lab tests, body composition, and metabolic history—to help patients from Aurora to Lone Tree achieve sustainable results.

Expert Management of Wegovy®, Zepbound®, and Metabolic Health

As the Past President of the Obesity Medicine Association, I am committed to using the most advanced scientific tools available. My role is to serve as your medical partner, customizing a plan that may include FDA-approved anti-obesity medications such as semaglutide (Wegovy®) and tirzepatide (Zepbound®).

Why Choose a Board-Certified Weight Loss Doctor?

  • Safety: We carefully monitor GLP-1 usage to manage side effects and ensure safety.

  • Precision: We tailor dosages based on your unique metabolic response.

  • Comprehensive Care: Medication is most effective when paired with the nutrition and behavioral support provided by our team of Weight Loss Dietitians.

Whether you are driving in from Littleton or Englewood, our goal is to provide the accountability and expertise you need to turn temporary weight loss into lifelong health.
