Dr. Tom Messinger is a licensed Naturopathic Doctor. Prior to becoming an ND, he was a Registered Nurse for 23 years, spending most of his career working in inner city Emergency Departments/Trauma Centers. He was founder and Clinic Director of Portland Natural Medicine in SE Portland. He has a highly successful practice specializing in the diagnosis and treatment of tick-borne diseases, chronic infections, and digestive issues. His education in Lyme disease began by participating in foundational training with ILADS (International Lyme and Associated Diseases Society). He continued his education in Lyme disease by doing extensive research and by taking multiple trainings with Dr. Klinghardt, MD, PHD (a well-known Lyme disease specialist) and the Klinghardt Academy. He is also a member of the International Society of Environmentally Acquired Illness (ISEAI) which has furthered his understanding on how to evaluate and treat environmental illnesses that can significantly impact health.

He has been a speaker on the subject of Lyme disease. He was the guest speaker on a Portland Radio show discussing Lyme disease in Oregon. Here is the link:

He was a featured speaker in the SIBO Summit II speaking about SIBO and Lyme disease. In 2017 he spoke at the Lyme disease and Co-morbidities seminar, a training given to physicians on Lyme disease and related topics. 

Many of the patients Dr. Messinger sees have been to numerous doctors but continue to have persistent health issues.  He has found that most chronically ill patients have multiple, if not numerous factors contributing to their health issues.  He utilizes a number of tools to assess what may be the root causes of patient’s health issues. After finding the imbalances and prioritizing the order of treatment, he  uses an individualized combination of treatments to assist in the restoration of health.
