Sauk Valley Under 40  (formerly known as the Keystone Group) is a joint initiative of the Sauk Valley Area Chamber of Commerce and Sterling Main Street.  Established in 2018 to amplify the voices of individuals under the age of 40, Sauk Valley Under 40 is where the next generation of leaders, doers, and difference-makers come together. We connect ambitious individuals under the age of 40 from across the Sauk Valley who are ready to build meaningful relationships, grow personally and professionally, and play an active role in shaping the future of our region.

Whether you’re a young professional, entrepreneur, skilled tradesperson, nonprofit advocate, remote worker, or community volunteer, this is your space to plug in. Through engaging social events, hands-on community involvement, leadership development opportunities, and authentic peer connections, Sauk Valley Under 40 is building a strong, supportive network that invests in both people and place.

We believe the future of the Sauk Valley depends on the people who choose to show up for it. This group exists to make that easy — and fun.

Sauk Valley Under 40 is open to anyone under 40 who lives or works anywhere in the Sauk Valley region — no specific town required. and is accessible to emerging leaders across all industries and backgrounds.

Come build your network. Find your people. Make your mark.
