The Diet Doc After Hours

Sign up to be entered into a monthly drawing for a free consultation with Joe Klemczewski, PhD, (Founder) and Kori Propst, PhD, (Wellness Director). But there's a catch — you're going to share that experience with the world!

Joe and Kori want to merge their professional and personal lives with friends in a new way and see if this experiment can make the world a little more fun. If you win the drawing, you can ask any questions about health, nutrition, or fitness--nothing is off limits. You can dip your toe in the waters of health psychology, behavioral medicine, sociology or anything that intersects your interests and our experience. You can even just hang out for an hour and sip tequila. The format will link our San Diego headquarters and our Evansville administrative center. You can be present in either location, or you can stream into the conversation. We're looking forward to hanging out after hours with our shoes off and our minds open!
