The National Hemp Association is primarily an all-volunteer organization with limited staff and volunteers who have become essential in the successful operation of the Association.

Below are the people behind the scenes to help make NHA the best resource around. Thank you!

Erica Stark Executive Director – Erica Stark, a former business management executive, took a leap of faith to leave her job and become a full time advocate of industrial hemp and medicinal cannabis long before it was clear that the tide of popular opinion had turned.

Today, Erica has seen out the success of her early efforts and has transitioned from activist to educator and coordinator when she became the Executive Director of NHA in 2017. Erica is also the Executive Director of the Pennsylvania Hemp Industry Council and serves as the co-chair of the Policy and Regulation Subcommittee of the PA Hemp Steering Committee which is the official advisory council to the PA Dept. of Agriculture. Erica was instrumental in enacting legislation in Pennsylvania and is proud to have been managing permits and growing hemp in PA since 2017. She is a sought-after speaker with years of experience in hemp education and legislative advocacy, including testifying before Congress. The industrial hemp industry has experienced a rebirth, legally, and now it is time to fuel the fires and continue to breathe new life into the fledgling industry, both locally and nationally.  Please contact Erica at

Anna Chanthavongseng Assistant Executive Director Anna was a former early childhood teacher and assistant director who trained staff and encouraged teachers to implement kinesthetic and nature-based learning to young children. Her love for sustainability and nature brought her to her first hempcrete workshop in Robesonia, PA in the year 2015. Since learning more about the plant she has been sharing knowledge about the diverse crop through her personal social media pages and with some graphics work. She continues to learn and spread awareness about the plant by attending hemp focused events and promoting businesses and manufacturers in the industry. She is also the co-founder of a new sustainable apparel business, Jasper & Ivy, that focuses on products made with hemp blends. She sees a promising future with hemp in our country and looks forward to working with it.. Please contact Anna at

Mell Green – Blog Writer & Volunteer

Mell Green is a 4’ foot-something writer with a body of work that covers a range of topics, however, her primary focus is hemp. Over the last few years, she has advocated for changing the way people perceive the plant and has also worked diligently to build solid relationships with other passionate people in the industry. Yet, she knows there’s so much more for her to learn and do. When not fighting the good fight, she’s dabbling in all things creative or discussing travel plans with her favorite humans. If you enjoy hemp as much as Mell does, catch her work in notable publications such as Terpenes and Testing Magazine, the Weed Blog, and many others.

Jennifer LiskeVolunteer As the former owner of a brick and mortar business in the upholstery industry, Jen brings 20+ years in sales, client service, consulting, and management experience. Her love for business, has given her a broad array of areas of expertise, including warehouse work, wholesale and procurement research. She is currently freelancing in several areas, including website design, some copywriting, and the craft of Internet/web research specialist, which she loves.

This next phase of her life is being devoted to industrial hemp, all she can learn about it, and to support the progression and diversity of the industry as well as the plant itself. She looks forward to her journey, along with helping the restoration of a self sustaining America that will come with this plant and it’s endless possibilities, with a focus on fiber uses and possibilities. She brings her love, focus and know how of building things and processes from the ground up, along with a high adaptability to change. Traits that are attributable to these ‘growing pains’ (no pun intended) that are currently the American Hemp Industry. As an avid Detroit Tigers fan, she can be found taking in games during the season. She loves listening to music, reading, walking, or just being a bum in the sun, soaking up the rays.

Les Stark – Social Media Volunteer – Les is a Pennsylvania hemp historian who has spent thousands of hours researching the historic Pennsylvania hemp industry. He has documented the existence of hundreds of hemp mills throughout the state and uncovered an epic tale of the days when nearly every farmer in the state grew hemp.

Since 1997 he has been teaching this information to farmers, farm organizations, historical societies, community groups, the media, legislators and the general public. He is the author of Hempstone Heritage I and intends to publish an additional 600 pages of his research which will tell the full story of great historic Pa. hemp industry. Although he has a deep passion for history, his true passion is in helping to rebuild the hemp industry.
