Founded in 1959, Carlson Building Maintenance has spent over six decades serving retail, grocery, and commercial clients. By bringing the Minnesota-based operator into the fold, Sizemore gains a specialized retail service arm and a robust, self-performing workforce. Carlson owners Nick Giese and Kaylee Brown will remain at the helm of the division to ensure continuity for their long-tenured client base.

Inspirit Equity, the Los Angeles-based firm backing the transaction, views the acquisition as a critical step in its buy-and-build strategy for the facilities management sector. Managing Director Ryan Kanaley stated that the firm remains focused on acquiring regional operators to solidify a national service provider. For Sizemore CEO Preston Sizemore, the merger is defined by a cultural alignment and a shared commitment to service execution. While the financial terms of the agreement were not disclosed, the move positions the combined entity to aggressively pursue new geographies and expanded service offerings across the Midwest and beyond.
