Dr. Angela Stengler, NMD, MS

Dr. Stengler is a licensed naturopathic medical doctor who has a passion for helping patients using nutritional and natural therapies. Her introduction to holistic medicine began in college during her junior year abroad while studying in England. She experienced first-hand the dramatic healing effects of a topical herbal therapy prescribed by a nurse for her injured foot. This positive experience, along with support from her pre-medical advisor who was researching the use of Chinese mushrooms and cancer, led to her decision to focus on integrative medicine instead of conventional medicine.
