Ann F. Corson, MD

Board Certified in Family Practice & Integrative Holistic Medicine


About the Practice

As an integrative family physician, Dr. Corson treats chronically ill patients within the framework of German Biological Medicine. This unique field of medicine integrates modern Western medical science with traditional herbal medicine and bio-energetic medicine all molded by the philosophies of ancient Chinese medicine.

Dr. Corson's practice focuses on identifying and addressing the root cause of each patient's illness and uses interventions that aim to provide a better quality of life that will last a lifetime. 

The practice's pharmacopeia includes spagyric homeopathic and immune-modulating medicines, herbal medicines from cultures around the world, nutraceuticals and allopathic drugs. This method of treatment is used to steer multiple generations of sick family members onto the road to better health. 


Medical Services

The practice treats a variety of chronic illness patients.

Vector Borne Illness/ Lyme Disease

Vectors are organisms that can transmit infectious diseases such as bacteria, parasites and viruses between humans or from animals to humans. Most vectors are bloodsucking insects which ingest disease producing microorganisms from an infected host during a blood meal and later inject them into a new host during a subsequent blood meal.

Biotoxin Illness/ Mold Illness

Biotoxin illness results from the exposure to biological toxins from indoor toxic molds and other types of algae and infectious agents. Common symptoms of biotoxin illness include chronic fatigue, joint and muscle pain, anxiety, depression, irritability, headaches,  increased sensory hypersensitivity, poor memory, cognitive dysfunction, disorientation, sleep disorders, and chronic respiratory symptoms such as sinusitis, allergies and asthma.

Chronic Illness

Multiple symptoms that persists for a long period of time, usually greater than 3 months, constitute chronic illness. There are many etiologies for chronic illness such as infection, indoor toxic mold exposure, heavy metals, glyphosate and other environmental toxins, electromagnetic radiation, nutritional deficiencies and poor diet.
