Knowing we all have unique genetic expressions of wellness and illness, Melissa employs a “Don’t Guess……….Test” approach. In her practice she relies on highly specialized laboratory tests that consider ones genetic, environmental and lifestyle factors to determine each patient’s unique needs.  

​

Having personally utilized these tools to drastically improve her own autoimmune challenges, she has developed a hands-on real-world approach to managing health and wellness for her patients. As a mother of a child with ADHD, she has also personally witnessed the marked improvement in wellbeing by marrying a “food first” approach with appropriate testing and supplementation. 

Most people don’t realize that disease begins with low levels of chronic inflammation that go virtually undetected until you start to see the signs. Autoimmune disease, inability to lose weight, hormonal imbalances, brain fog, fatigue, joint pain, digestive distress, skin problems and anxiety are just some of the disorders that can be improved upon once you uncover the root cause and apply the proper dietary and lifestyle changes that are tailored to your body.
