Dr. Miriam Mendelsohn is a board-certified Naturopathic Physician who provides a holistic and preventative approach to healing. Her philosophy on health begins first and foremost with listening, with the intention to find the root cause of patient concerns. In order to best provide care for her patients, Dr. Mendelsohn takes a detailed medical history for every individual and utilizes a variety of labs for additional data collection. She feels strongly that a patient should fully understand lab results, diagnoses, and treatment plans before ending her visit.

In addition to clinical interpretation and data management, Dr. Mendelsohn aims to provide a safe space to all. She works hard to cultivates warmth and trust between doctor and patient. She treats adults and children of every background, including every race, gender, and sexual preference. In addition, Dr. Mendelsohn appreciates that not every treatment path is appropriate for everyone, and creates an individualized treatment plan for every visit. 

Dr. Mendelsohn specializes in complex illnesses including tick-borne diseases such as Lyme, mold and mycotoxins, mast cell activation syndrome, environmental toxicity, PANS/PANDAS, and other inflammatory or infectious disorders. She has received extensive education in these fields from ILADS (International Lyme and Associated Diseases Society), mentorship and training with Dr. Julia Greenspan, Dr. Jill Crista, and Dr. Pejman Katiraei. She has also receiving training  and certificates from Dr. Neil Nathan, and Dr. Richard Horowitz.

Dr. Mendelsohn also has experience with hormone replacement (including bioidentical hormones, thyroid hormone), anxiety, depression, gastrointestinal complaints, and general wellness. She has received a certification from Dr. Dale Bredesen upon completing his “End of Alzheimer’s” program called “ReCode.” In addition, she received a certificate for completing a program through Dr. James Greenblatt in Functional and Integrative Psychiatry specializing in nutritional support. In 2025 Dr. Mendelsohn will also be available for consultation and treatment regarding Greenhouse Natural Medicine’s weight loss program.

At home in Merrimac, Massachusetts, Dr. Mendelsohn enjoys spending time with her husband, daughter, and odd assortment of house goblins (her cats). In her free time, she expresses her artistic side with metalwork, printmaking, painting, and textile arts.
