The St. Louis Jewish Community Center (the J) is nearing completion of a major renovation of its Marilyn Fox Building in Chesterfield, part of the “Creating the J for Tomorrow” project. The effort, which wraps up in September, marks the end of an 18-month construction process aimed at creating a more inclusive, welcoming space for members of the Chesterfield community and beyond.
The Fox Family has played a central role in the J’s Chesterfield story since the beginning. Marilyn and Sam Fox z”l helped lay the foundation for the building that bears Marilyn’s name, and their family continues to be deeply involved in its growth. Their most recent support includes a significant gift to the renovation campaign and a $1 million matching challenge to encourage additional giving.
What’s changing
The renovation brings expanded programming and upgraded spaces to the Fox Building. One of the most notable additions is a second Adult Day at the J location, which opened in April 2025 and serves seniors with memory or physical challenges, as well as young adults with cognitive disabilities. Modeled after the successful program at the J’s Creve Coeur campus, this new center helps meet a growing need in the Chesterfield area.
The improvements also make it possible for programs typically held at the Staenberg Family Campus—such as the St. Louis Jewish Book Festival and Nishmah—to now be offered in Chesterfield as well.
Completed renovations in Phases 1 and 2 include:
- Redesigned Community Commons areas
- Updated restrooms
- New men’s and women’s locker rooms with infrared saunas and steam rooms
- A renovated Family Center for youth and family programming
- A new Mind Body Studio, kitchen, recovery room and community locker room
Currently underway in Phase 3:
- A new Group Exercise studio
- Updates to the Early Childhood Center
- Dedicated indoor pickleball space
- A refreshed building exterior and parking lot
Honoring a Legacy
In recognition of their ongoing commitment, the Chesterfield campus will now be known as the Marilyn Fox Building on the Marilyn and Sam Fox Campus. The naming honors the family’s legacy and long-standing involvement in the J’s mission.
The campaign has raised nearly $13 million to date, thanks to the support of many donors, including:
- The Fox Family
- Michael H. Staenberg and the Staenberg Family Foundation
- The Kuhn Foundation
- The Lefton Family
- The Harlene and Marvin Wool Foundation
- JCA Charitable Foundation
- J.E. and L.E. Mabee Foundation
Real estate developer and philanthropist Michael Staenberg, who has supported the J in various roles over the years, has provided both financial backing and project leadership. Reflecting on his involvement, he said: “Because of the history with the Fox Family at the J and the growth of Chesterfield, the Marilyn Fox Building is an essential part of the community. I wanted to inspire others to give—I’m a true believer in the ripple effect.”
Steven Rosenzweig, the J’s president and CEO, noted the importance of community support: “The generosity of our donors makes this project possible. Their commitment helps ensure the J remains a place where people of all ages can connect and grow. We’re especially grateful to the Fox Family and to Michael Staenberg for their vision and dedication.”
Looking ahead
While much has already been accomplished, additional support is still needed to fully realize the goals of the “Creating the J for Tomorrow” campaign. This effort isn’t just about upgrading a building—it’s about investing in a stronger, more connected community for years to come.
The campaign is being led by co-chairs Debbie Lefton and Greg Siwak, who are helping to coordinate efforts and keep the momentum going.
All contributions will be matched dollar for dollar—up to $1 million—thanks to the Fox Family. Gifts made by July 30 will be included on the Staenberg Impact Wall in the renovated lobby, in time for the Sept. 4 dedication. Names of donors who give after that date will be added at a later time.
