Dr. Glen Nagel is one of the most notable experts in botanical therapies in the field of naturopathic medicine. “My personal goal has always been to be the most versatile and well rounded, botanically focused naturopathic doctor that I can be. I strive to develop an understanding of herbs from the seed to the clinical prescribing of botanical medicines. I have a deep love and respect for the healing herbs and strive to teach others about them.” Dr. Nagel has extensive experience treating:

●  Allergies
●  Sinus conditions
●  Fatigue
●  Digestive problems
●  Men’s health

In addition to using botanical medicines, Dr. Nagel focuses on nutrition, homeopathy, and detoxification. He has been studying botanical medicine for nearly three decades; apprenticing with Ed Smith, the founder of Herb Pharm, and subsequently working for Eclectic Institute, setting up their herb extraction lab and production facilities.

Dr. Nagel earned his BS in Outdoor Education from Northland College in Ashland, Wisconsin. It was during this time, that he read Euell Gibbon’s book, Stalking the Healthful Herbs, which officially launched his interest in pursuing a career in botanical medicine. His work at Eclectic Institute turned his attention to naturopathic medicine, and he earned his Doctorate in Naturopathic Medicine from National College of Naturopathic Medicine (now National University of Natural Medicine) in 1993.

Dr. Nagel is a registered herbalist by the American Herbalists Guild. His current focus is educating naturopathic students in the area of botanical medicine, and to keep the nature in naturopathy through field study and clinical supervision. In his spare time, Dr. Nagel enjoys singing, playing the mandolin, and camping and hiking with his family.
