Our Expertise

As you explore our website, you will discover that we can deal with most medical problems, as a common theme runs through virtually all the ills of men and women – chronic inflammation.

The root causes vary, and the flames may manifest in different ways, but the fundamental process needed to detect the underlying causes is common to all. Environmental toxin exposures, hormonal imbalances, nutritional deficiencies, epigenetic expression, sleep and circadian rhythm disruption, trauma, issues of stress and relationship problems, lack of exercise and poor fitness status, and chronic infections are all key players to be evaluated.

Once we have determined the origins of your inflammation, we will work as a team to develop a unique therapy plan… just for you. We never forget why you searched for us, and what you are looking for… the recovery of your health and happiness.

Personalized Healthcare for Your Needs

We strongly believe that there can be no set IMGI “program,” a cookie-cutter treatment protocol for one and all. You are as unique as a snowflake, and require and deserve a therapeutic plan designed exactly for your needs.

This is called “Personalized” or “Precision” medicine…the medicine of the future put in play today. We firmly believe that the “one size fits all” approach to healthcare simply fails to address the overwhelming complexity of the human body!

We invite you to start your journey back to health!
