In 2016 with my experience in agriculture, creating successful business entities, and skills helping teams to reach their goals, I was asked to consult a group of investors to build and begin the operations of a new Recreational Cannabis farm in Oregon. I was up for the challenge to use all my skills to create something new and progressive. I consulted with their team for a year and we worked diligently as we became one of the top 5 companies producing and manufacturing. We won many awards and added a distribution license and edibles line to the business portfolio. At the end of my contract, it was proposed I stick around and continue leading the team and sweetened the deal by offering me shares of the company and becoming co-owner of what we built. I accepted. With a 2 million dollar investment, we have proudly evaluated at 9 million. I started to take less responsibility as General Manager with a plan to offer my experience as a consultant in the cannabis industry. After assembling a great crew I did just that. I currently offer consulting services to both food service and agricultural companies across the U.S. I am a single male with 2 daughters, 20, and 17 that live at college, I prefer to work a lot, and I enjoy having a purpose. Whether you are looking for help on a small project or for an employee willing to do what it takes to get the work done and with excellence, and believe like me that loyal, hard-working committed team members may not exist, I would like to prove you incorrect. If you require or would like to view a CV/resume I can supply one.
