BOULDER HEMP is a collective of scientists, engineers, innovators, farmers and medical professionals, dedicated to providing access to hemp, and driving scientific hemp research forward.

We grow all of our hemp in Boulder County, Colorado--at an elevation of 4,995 feet above sea level, using strictly organic cultivation practices.

All products are carefully crafted in small batches, using a science driven approach, and tested by multiple independent labs for purity and potency. 



Ryan Lynch, PhD. CO-Founder

Ryan began his involvement with Cannabis by channeling his lifelong passion for horticulture and botany to assist with small scale grow facility development during the early emergence of legal commercial Cannabis cultivation in Colorado.  At the University of Colorado Boulder, he developed a set of PhD projects that centered on the analyses of DNA sequence information to understand biological diversity, function and evolution. While his research was initially focused on microorganisms, following the passing of Amendment 64, Ryan helped bring Cannabis genome and plant science research to CU Boulder. He operated the first ever (authorized) campus Cannabis grow and breeding facility, crossing and inbreeding European and Asian hemp varieties—and was awarded the first ever Cannabis biology based PhD from the University of Colorado. When he’s not tending to plant breeding and cultivation projects, Ryan enjoys year round exploration of the mountain wilderness that lies just upstream from the Boulder Hemp farms.


Jeremy Widmann, PhD. CO-Founder

Jeremy attended the University of Colorado Boulder where he obtained his PhD in biochemistry, focusing on RNA evolution and function.  His work focused on large scale computational analyses, studying patterns in RNA sequences across all domains of life, giving insight into the origin of life from an RNA world.  Interested in human health and genomics, Jeremy took a position at the molecular diagnostic startup, ArcherDx.  As Asst. Director of NGS Assay Design, he developed the software suite used to design Archer’s human cancer diagnostic tests.  Jeremy’s experience with Cannabis includes over a decade of cultivation, implementation of an extraction facility in a commercial Cannabis grow, and most recently as Co-Founder of Boulder Hemp.  Combining his passion for Cannabis, evolution and human health, Jeremy hopes to aid in development of Cannabis-based personalized medicine.  When he’s not in one of our cultivation facilities or in the lab formulating new products, you’ll find Jeremy on the track racing his motorcycles or up in the mountains hiking and fishing.


Kathleen Widmann, RN. Managing Partner & Director of Production

Kathleen raised a family in Steamboat Springs, then headed to San Diego, and eventually pursued a nursing career.  She practiced as a Registered Nurse for many years at one of the largest hospitals in San Diego.  The time finally came for Kathleen to move back home, and joined the team at Boulder Hemp in 2017.  Kathleen is committed to the research, science and the mission of bringing CBD to all.  She brings with her a heart for the health and wellness of all people, her years of nursing experience, and an organized mind.  When Kathleen is not in the shop assuring smooth production of our CBD products and shipping to our customers, she enjoys the outdoors, travel and hiking.
