Center for Health Science is a group of clinicians and research scientists dedicated to bringing the strength of scientific evidence to the treatment of health issues.  CHS offers medical testing, professional guidance and scientifically proven neutraceuticals, all available without prescription or physician referral.

CHS was founded by David Reinhardt, Ph.D., A.B.M.P.,  a medical research scientist, licensed and board certified Medical Psychologist, Psychopharmacologist and Holistic Health Practitioner.  He, and his staff of qualified researchers and licensed health professionals, are available for consultations.

Our Philosophy:

CHS believes in Functional Medicine, the investigation and treatment of causes rather than the suppression of symptoms.

We at CHS are reluctant to buy into the term “idiopathic” (arising spontaneously or from an obscure or unknown cause) in health issues such as hypertension, blood sugar abnormalities, cancer or endocrine issues.  We reject the notion that ANY health problem “arises spontaneously”, a primitive notion of medicine.

The CHS Approach to Health:

1.  Look for causes of symptoms with medical lab testing supplemented with careful consideration of all body systems and client-centered information gathering.

2.  Provide feedback to guide additional lab testing and data collection.

3.  Alter lifestyle choices when found to contribute to poor health.

4.  Use appropriate, targeted nutritional supplementation.

5.  Utilize the help of health specialists as appropriate from allopathic physicians, surgeons, psychologists, psychotherapists, western herbologists, doctors of Chinese and Ayurvedic medicine, naturopaths, accupuncturists, chiropractors, nutritionists, physical therapists, physical trainers and other members of the collaborative medicine community.
