John de Guzman, MD
Obesity Medicine Certified Physician
If you’re looking for an experienced and proven weight loss doctor in Phoenix, you’ll find him at Scottsdale Weight Loss Center‘s Biltmore location. Dr. de Guzman had been treating patients for chronic health issues including high blood pressure, high cholesterol, diabetes, heart disease, and joint pain for years in his former internal medicine practice. It was frustrating because rather than treating the root cause of these chronic conditions–obesity–he was treating the symptoms.
At Scottsdale Weight Loss Center he now helps patients get healthy and stay that way through personalized weight loss programs that are proven, safe and comprehensive. Before joining Scottsdale Weight Loss Center, Dr. de Guzman referred countless patients to the Scottsdale location, he believed that much in their approach. And his patients lost weight, got healthier and stayed that way long term. He has always loved when people in his care experience improved health and well-being. That’s a regular occurrence for him at Scottsdale Weight Loss Center.
