Hi!
I’m a doctor specializing in weight management, preventive medicine, and public health. I’m not a “diet doctor” or “weight loss doctor.”
I’m on Faculty at Johns Hopkins University and George Washington University. I work alongside many others in the public health and health policy fields to help make it just a little easier to be healthy in our society.
My office is in Washington, D.C. at the National Center for Weight and Wellness, and I treat patients throughout the U.S. and internationally. We build productive and long-term relationships. They say really nice things about me.
Please look around my website, read my blog, or contact me. Here are a few recent blog entries:

PBS Roundtable
As part of a PBS Roundtable discussion on obesity, I was asked to share my thoughts on “junk food taxes.” This brief clip describes the many determinants, or factors, that go into our behaviors and choices. One of the key factors is cost. All else being equal, when something costs a relatively large amount, there is a lesser chance that we’ll spend our money on it; if it becomes cheaper, there is a greater likelihood that we’ll purchase it. This is “Economics 101.” Read more
