I rely on both my unbridled curiosity and appetite for knowledge and exploration in my pursuit for continuous improvement. As an ambassador of the Impact brand, I harness this mindset to work effectively with my colleagues to increase our brand awareness and build mindshare in the marketplace. In my spare time, you can find me in the mountains skiing, hiking, and fly fishing with my wife and hound dog.

Mario andGianAndrea
President and Founder

I’ve been many in my working life: an HR Director, an entrepreneur, a leader, a coach, a salesman, a visionary, a confidant, a manager. And a friend. And I am still excited (and sometimes anxious) when I meet a new group of people. I genuinely enjoy it! This is the reason I'll probably work for another decade! The only difference compared to the past: today I can afford to only work on projects and with people that I really like and that gives me the feeling that it will be great fun!

Kate andWolf
Sr Director, Client Services

I’ve spent my career partnering with clients to solve problems and drive their organizations forward. As Teddy Roosevelt (and then Leslie Knope) shared: “The greatest gift that life can give is to work hard at work worth doing.” I’m honored and thrilled to do meaningful work with my colleagues at Impact, leveraging powerful experiential learning experiences for our clients to create the ‘leaders they wish they had’. Outside of work I love to explore the beauty of Oregon by foot, bike or boat.

Global Lead

After 10 years leading the UK, I am now in a global role focused on two areas: one leading a people project, the other focused on marketing. I grew up through Impact as a marketer and love the buzz of building business through brand and storytelling. My other passion is the people and culture here, so this is the ideal combination for me. When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.
