This course will be taught by Wade Atteberry, who has been in the industrial hemp industry since 2012 doing research and development work on carbon-negative hemp building materials. He is known internationally and recognized as one of the leaders in the industry for his innovative hemp building materials and processing equipment. He is a patented inventor in the industry and has consulted on dozens of projects, as well as building out many proofs of concept. He is also fresh off his heels from Oregon State University’s Global Hemp Innovation Center’s “Teach the Teachers” program.
Wade was the project build manager for a highly customized 10×20 Tiny Hemp Home built in a laboratory on campus to showcase many different types of popular hemp building products. This was a month-long project culminating in a one-week course put together by professor Dr. Jeffrey Steiner and professor Dr. John Simonsen. During this course, you will have one-on-one time with Wade to ask questions and get consulting on your future projects.
Best regards,
Wade Atteberry
