Core Team Members Include:

Judith Mattson (Co-Chair)
Bio: Judith Mattson is an experienced writer and consultant based in Tucson. To date, she has worked with over 100 consulting clients and employers in more than 25 states, originally from a base in the Washington, DC area. While her primary career has focused on healthcare and health insurance, she has concurrently pursued her passion for food-related interests, including food sourcing, marketing, preparation and writing. Her focus on climate and sustainability of our home places has flowed naturally from her work with food and health in these changing times.
Along the way, Judith has often focused specifically on local organizations within food, healthcare and the communities in which she has lived — community health centers, physicians, hospitals, small local health plans; local food producers, local and natural food outlets, restaurants; arts; events; and political interests. She has been active in both state and national associations for health care and local government interests.
Today, she blends the best of this experience and expertise in writing, marketing, customer service, consulting, publishing and regulatory affairs through a business focused on natural and local food concepts. She holds a BS in Home Economics and Journalism from University of Nebraska at Lincoln. Before moving to Tucson in 2007, Judith lived in Colorado for 17 years, most recently the Denver area, which is home to her two adult children and families.
