Our Team

In 2014, Fiona founded Mainspring following twenty years of experience in international and corporate law, concluding with a seven-year tenure as EVP and General Counsel at Vail Resorts. She then served in Governor Hickenlooper’s cabinet, where she led Colorado’s Office of Economic Development and International Trade for two years.

Deeply engaged in her community, Fiona has served on numerous nonprofit, education, workforce, government, and civic boards. Mainspring emerged from her passion for making a difference in the local area and transforming spaces and experiences, uniting creativity with problem-solving.

When she’s out of the office, you’ll find Fiona outdoors, digging in the dirt, biking, enjoying good food, and spending time with her dogs.

At Mainspring, he is responsible for providing strategic, financial, and operational leadership for the company and its portfolio of investments.

While not working, Andy prioritizes dedicating quality time to his family, sharing meals, sporting events, and experiences. He is also passionate about and committed to his fitness and maintaining an active lifestyle.

If you’re up at zero dark thirty, most days you can run into Andy at the gym, on a bike, on the trail, or skinning his way to the top of his favorite back country ski slope.

After a stint in the military, a degree in finance, and a cubicle in NYC, Jeffrey decided it was time for a change. He grew a beard, moved to Colorado and became a barista.

As much as he loved coffee, and loved being a barista, he needed more. After managing his first coffee shop, he had an opportunity to help open and manage a new café in town. From there he launched his own consulting business which is how we met.

After working with us to help open our first blue sparrow coffee location, Jeffrey joined us as a co-owner and the operating partner of our Blue Sparrow coffee division.
