Dr. Manuel Diaz

IFFHealth - Manassas

Dr. Manuel Diaz DC, D.PSc, is proud to be the only doctor in the Greater Washington DC metro area certified by the Institute for Functional Health and now offering the Total Health Transformation Program at his Manassas, Virginia clinic--Momentum Chiropractic & Rehab.

This program ushers in a revolution in healthcare as patients take control of their own health and stop relying on an endless cycle of medications and side effects.  Through intense testing, patients learn the root cause of chronic conditions that have kept them on medications for years.  

Dr. Diaz works hand in hand with his Wellness Liason, Ashlee Memitt, to customize a health plan that takes into account your current state of health, while carefully adjusting for your unique genetics, and empowering you to make the changes to your nutrition and daily activity that leads to real health and wellness.

Success is not defined by "good labs" as prescribed by a physician, whose only recourse is typically more medication. Instead, success at the Institute is a state of health & well-being where medications are un-necessary because the body can heal itself and properly maintain its natural state.

Some services offered by the Institute may be covered by your heath insurance. For services that are not covered, Dr. Diaz has partnered with CareCredit to offer interest-free financing for up to 12 months to fit any budget. Many patients actually report the program paying for itself many times over based on their change in lifestyle and reduction in co-pays for doctor visits and medication.
