About the Herbalist

Marija grew up running wild in the woods. (Well, at least ’til sunset.)  She’s a research scientist-turned-clinical herbalist, practicing since 2009.  Marija studied botanical medicine in the Bay Area with Pam Fisher, Kathi Keville, and others. She is a doctoral-level microbiologist who worked in cancer- and infectious disease research.  Despite the high tech past, Marija’s focus as an herbalist is a simple approach to health that integrates herbal traditions with botanical research science.  According to the World Health Organization, herbs are used in support of health by 80% of the world’s population. More information on Marija’s training as an herbalist and scientist can be bound at the bottom of this page.  Other interests include wild food foraging, gardening, martial arts, and all things 2-wheeled.      

Marija is also an herbal educator and a freelance writer.  She’s a columnist for Plant Healer Quarterly, was a weekly contributor for 2.5 years for Basmati, a wellness site, and has written for a variety of outlets in the Four Corners Area.  In addition to offering classes through Osadha Natural Health, she’s taught for the following organizations:
