We are the Dream Team!

A common theme runs through virtually all illnesses affecting men and women: chronic inflammation.

Although the root causes can vary, there are common processes that need to be evaluated in order to detect the underlying causes.

After taking a detailed history, we explore a variety of possibilities including environmental toxin exposure, hormonal imbalance, nutritional deficiency, epigenetic dysregulation, sleep disturbances and circadian rhythm disruption, trauma, stress and relationship issues, your exercise and fitness status, and chronic infections. Our team then develops a unique therapy plan tailored just for you.

Achieving optimal wellness is a process that takes time, and can require often dramatic changes to your diet and lifestyle. The team at IMGI is here to help. New patients will visit with Dr. Felice Gersh for an hour, during which time she will discuss your issues, develop a customized plan for you, and refer you to the appropriate medical team members and staff. They will explain how their work combines to provide you the holistic, integrative treatment required for complete, whole-body wellness, and you will be assigned someone that oversees your care.

It’s essential that you embrace a comprehensive solution to your medical problems, rather than looking for a quick, miracle-pill cure. A long-term, sustainable plan that treats the causes of your ailments – not just the symptoms – is your best hope for a successful, side-effect-free resolution. Your healthcare team will be there to help you through every step of this journey.

We understand that you may have already been to many doctors, receiving no real answers and many unsatisfactory treatments. The suffering and fear continue. We are here to change your future!

By taking the skill sets of these remarkable doctors, and designing a completely unique therapeutic plan of action for you, we have taken integrative, functional, and holistic medicine to a new high plateau.
