Anne Mercer Larson

Anne Mercer Larson, MOB
Dir. of Strategic Initiatives, Marketing and Public Relations

Joining Prebiotin in March of 2016, Anne first contacted them as a customer. Conversations began with Ron Walborn Jr., CEO, and soon evolved into an offer to join the Prebiotin team.

“It has been a terrific experience. I was very involved in reading and research about the microbiome and prebiotics, however, I wasn’t looking for work,” Anne relates.

Anne has the deepest respect for the work it took the founder, Dr. Frank Jackson, to create Jackson GI Medical, and his passion for the value of prebiotics to contribute to a positive change in our sometimes dysfunctional gut health. The product has made a huge difference for her after her bout with breast cancer treatment several years ago, and she is passionate about Prebiotin’s mission.

With her extensive experience in strategic planning, marketing, and public relations, Anne has had a hand in nearly every aspect of the company’s growing business.

Anne helps support all of the content, sometimes writing it herself, and looks for opportunities to build relationships with organizations like The Peggy Lillis Foundation which provided the first guest blog for Prebiotin.

Anne has consulted with physicians and hospitals and a premier producer of award-winning cancer videos and books on the development of marketing strategies and authored two peer-reviewed articles, one in Cancer Management Journal which was also included in the International version, and another for California Hospitals Magazine. She also served as executive director for two nonprofit foundations and spent several years in financial services.

She holds a B.A. from California State University Bakersfield and a Masters in Organizational Behavior from the California School of Professional Psychology.

“Sometimes the blessings you are looking for are not the ones you find –remember to look sideways!” -Dr. Judith Mercer Shrider, 1936-1996

Jody Patterson
Assistant to the CEO, Webmaster

While working with Jackson GI Medical’s CEO, Ron Walborn, Jr., at his accounting firm, Jody tried Prebiotin and became a devout advocate and was so impressed with the work and science that went into creating the products that she made the leap to working for Jackson GI Medical full-time.

With a background that included Executive Assistant, Full-Charge Bookkeeper, Teacher, IT Technician, Artist and Webmaster, she brought a unique skill set to the company and developed a solid vision of how she felt the company should be represented online.  The site you are viewing is the product of that vision (after much "reining in" by other team members) and it is her hope to continue to refine the site as the company moves forward and grows.
