An innovative consultative medical practice


We are excited to announce the launch of our new practice. The timeframe of restructuring our practice was abrupt due to unforeseen circumstances beyond our control. We understand that this sudden change is unsettling. Please know that we are working hard to get up and running as quickly as possible. Your patience is appreciated during this time of transition. We look forward to partnering with you to assist in your journey to wellness!

As an IFM Certified Practitioner of The Institute for Functional Medicine’s Certification Program (IFMCP), Dr. Zielsdorf is uniquely trained in the Functional Medicine model to identify and treat the root causes of chronic disease.

Of total healthcare costs in the United States, an estimated 86% are spent on chronic conditions. The current healthcare system is designed to treat urgent medical problems, also known as “acute” conditions. However, chronic, lifestyle-related diseases cannot be treated successfully using the same approach. What works is an individualized approach to patients—with an emphasis on the ways our environment and lifestyle choices interact with our genes. Functional Medicine is an innovative approach to medical care. It uses the latest medical research to develop personalized care for each patient, based on his or her unique environment, lifestyle, and genes. The result is a dynamic, effective way to address chronic disease.  

Dr. Zielsdorf joins an elite group of more than 800 practitioners who are certified through IFM’s Certification Program
