As a legislator I received numerous awards and recognitions, all associated with supporting greater access, and smart regulations, if needed. As a lobbyist and policy advocate I have remained behind the scenes as much as possible, because that is the most effective way of accomplishing the mission. I can brag that two pieces of my legislation were litigated before the United States Supreme Court (though I did not engage in that process), and during the 2016 Presidential campaign I served as a strategist for a campaign, and our client won that state with almost 70% of the vote

I have extensive ties in Utah, and Tennessee, and then throughout the education arena nationwide. I am typically no more than two phone calls from almost any element that we may need. It is a small, highly connected community.

I'm happy to forward my resume to potential clients. I'm a former State Legislator, where among other responsibilities I served in Extended Leadership, and Chaired an Education Committee. I've worked extensively in the charter school arena, having helped open over 100 charter schools in the past twenty years. I've also worked with the Gates Foundation, Walton Foundation, United States Department of Education, United States Senate and House, and many other related entities. I also have a very strong military background, which includes working with the Service Academies (ie West Point, etc), and currently serve as an Honorary Commander of the 419th Tactical Fighter Wing, the first operational unit to fly the F-35 fighter.
