Leaders in the research and treatment
of biochemical imbalances.
Our mission is to normalize biochemistry in children and adults through
research, development, education, and affordable clinical services.
Pfeiffer Treatment Center (PTC) is a not-for-profit, medical outpatient facility specializing in the treatment of symptoms from biochemical imbalances. PTC’s dedicated medical team treats children, teens, and adults with symptoms of behavioral and learning disorders (including ADD/ADHD), autism spectrum disorders, depression (including postpartum depression), bipolar disorder, schizophrenia, anxiety, post traumatic stress syndrome and Alzheimer’s disease. PTC takes a unique, integrative approach to identify and treat the root metabolic causes of these symptoms with a multi-disciplinary clinical team involving physicians, nurses, dietitians, pharmacists and other clinical specialists.
Individuals in the absence of symptoms of a biochemical imbalance may also benefit from a biochemical assessment to support health and promote wellness at our clinical headquarters (only) in Warrenville, IL - a southwest Chicago metropolitan city. Patients tell us that PTC's individualized nutrient program assists them in making healthier lifestyle choices in their quest for optimal health.
Since 1989, PTC has treated over 20,000 patients from all 50 states and from more than 75 countries, at our Centers in
Pfeiffer Treatment Center is named in honor of Carl Pfeiffer, M.D., Ph.D., founder of Princton Bio Center in Skillman, NJ, and pioneer in the field of nutritional research therapy. Dr. Pfeiffer became interested in the research conducted at Health Research Institute (HRI) and, before his untimely death in 1988, worked extensively with the HRI team to share his knowledge of correcting biochemical imbalances.
