Meet the team
Our team understands the role of private equity in supporting and empowering great management. We care about each other and extend our approach to everyone we work with.
A shared vision
Mark and Leon are the founding partners of Goldenpeak. Having first met in 2012, they forged a strong and trusted partnership working on numerous deal opportunities together. Over time, their approach led to a series of successful deals and exits—experiences that now shape much of Goldenpeak’s investment strategy. Their complementary expertise and close relationship are strengthened by a growing team who share their vision and commitment.
Our brand story
Reflecting the founders' love of the outdoors, the firm's name takes inspiration from a prominent mountain in the Colorado Rockies. Like the region’s Aspen trees all connected through a single root system that shares strength and sustenance—Goldenpeak believes deeply in partnership and working together to achieve exceptional results.
