Dr. Ziltzer will take his passion for getting people healthy and apply it to you. He helps you improve your health by addressing the likely root cause which is obesity-related. He established an internal medical practice in Scottsdale, Arizona in 1991, where he treated patients suffering from diabetes, high blood pressure, and high cholesterol. That’s when he realized he wanted to treat the root cause, obesity, not the symptoms. Through proven weight-loss programs that are personalized for you, your lifestyle and your goals, you’ll discover for the first time a truly effective way to not just lose weight, but keep it off.
