Michelle’s Health Story

While completing her dietetic internship Michelle started experiencing many debilitating symptoms. Traditional medical tests and doctors could not figure out what was causing her symptoms so she decided to reach out to alternative practitioners. Michelle found a doctor who utilized muscle testing in her practice and started to receive care. At the same time, Michelle was seeing a functional medicine doctor and was diagnosed with Lyme disease and mold toxicity from her new home she moved into right before beginning her graduate program. Nutrition response testing has put Michelle’s Lyme Disease into remission and her other chronic conditions have responded wonderfully. Through the use of nutraceuticals and other natural health methods, Michelle is now living a full and vibrant life. 

Michelle maintains an active practice in Hinsdale, Thursday through Saturday, and is the Dietitian at The LaCava Center for Integrative Medicine Monday- Wednesday
