SENIOR packaged Manager

While working at another Northern California co-op from 2002-2004, John realized he loves what co-ops stand for. In 2010 he saw the posting for Bulk Buyer at Chico Natural Foods Co-op and quickly applied. John had been working as the Bulk Buyer for slightly more than a year when the Wellness Manager position became available. Previous to taking the position of Wellness Manager his prior experience had been on the Grocery/Bulk side of the business. This position has been both challenging and rewarding for John, he has been learning everything he can about supplements and herbs, as well as the ins and outs of successfully running a department here at CNFC. 

John was born and raised in Red Bluff California, growing up in a very outdoor oriented family he learned at an early age the importance of conservation of our wildlife and natural resources.  He enjoys almost anything that involves the outdoors; from disc golf and fishing to hiking and camping.

Alissa joined the Co-op in 2013 with nearly 15 years of experience in management, consulting, team and leadership development, program development, project management, training and curriculum design, public relations, marketing, and fundraising in both the social profit and business sectors. In the social sector (City Year, Greenlights for NonProfit Success, OneStar Foundation, Austin Film Festival), she served in multiple capacities including direct service support to under-served schools and communities across the country, as well as, consulting and training to organizations on the front lines of addressing their community’s greatest needs. In the business sector (AllClear ID), she worked with highly stressed, and sometimes high-profile, clients under federally-mandated deadlines due to breaches in their data security.

Holly Riggs

Human Resources & FINANCE director
(530) 891-1713 x124

Coming from a business and Human Resources background, Holly is thrilled to be a part of the CNFC team. Shortly after college, she co-owned a retail electronic store in Washington State, managing the business and finances. Using what she learned from that business, she became a small business counselor and SBA lender for 7 years with experience in writing and processing business plans and loan packages.  She then started up and managed Wild Goats Coffee & Cafe in Kent, Ohio in 1996 where much the food served was organic (based on the somewhat limited availability) catering to vegan, vegetarian, and omnivores alike, before selling the business and moving to California in 2003. In 2007, Holly received her MA in Psychology with a focus on Organization Development – not only looking at strategic planning and business systems, but acknowledging the human element as a strong asset of a business. What better place to put that training into practice than in co-operative business! She worked in Human Resources at Ukiah Natural Foods and also as the Managing/Finance Director of Ukiah Players Theatre before moving to Chico in 2012.

Holly loves spending time with her family and stays involved in theatre by serving on the Board of the Blue Room Theatre.
