Team Tallgrasss
Hemp  & Cannabis


Among the many qualifications of the team, there is none more important than

love of cannabis plants. 


Sarah Stephens Selmon’s entrepreneurial heart leads the way at Tallgrass Hemp & Cannabis as Founder & CEO. She loves cannabis, activism, action on climate change, coffee, social justice and most importantly, her family.

An innovator in business, she founded Safe Riders, Inc. in 2003 at the age of 25—the service drove intoxicated individuals home, in their own vehicle. The business was innovative and forward thinking. It solved a very real problem that, as a bartender at Walt’s Bar & Grill, she believed could be positively affected by providing a service solution.

While earning a Master of Public Affairs degree from Wichita State University’s Hugo Wall School, Sarah worked in Republican politics. She managed campaigns for governor, mayor and state representative. She learned to prefer the parameters of entrepreneurship.


When the opportunity to first grow hemp arose in Kansas, Sarah submitted a successful research proposal and was the first licensee in the state. Assembling an experienced team, learning from available research, and committing to industrial hemp in Kansas, Tallgrass Hemp & Cannabis incorporated in 2019.
