I feel very passionate about access and inclusion in the outdoors, and I want everyone to know about and be able to enjoy the mental and physical health benefits that our trails can offer. I volunteer in order to bring a new perspective and challenge the status quo of both the internal and external work that PNTS does.

What are you most proud of?

Over the last decade I was lucky to have the opportunity to guide a few accomplishments regarding the outdoors at the national level. I helped establish and lead the Federal Interagency Council for Outdoor Recreation which did a couple of things that positively influenced progressive policies that benefitted national trails, spurred increased investment in conservation and enhanced acess to the outdoors. The first was working to define and measure the nation’s outdoor recreation economy which led directly to influncing decision makers to increase investment in parks and public lands conservation and recreation infrastructure like trails, at the national, state and local levels. Secondly, I am particularly proud of the role I had in helping create the national Every Kid Outdoors park pass program that has provided free passes to tens of thousands of kids and their families to get out and enjoy their parks and public lands and waters.
