At a recent Plante Moran partner meeting, a memorable moment captured the spirit of our integration. Tonneson shareholder Rich Eagleston took the stage — football in hand — to reflect on the journey that brought Tonneson and Plante Moran together. The football, signed by all of Tonneson’s shareholders, was presented to Managing Partner Jason Drake as a symbolic handoff. Now we’re ready to run the next play — together. Here’s to teamwork, shared values, and a future we’re building as one firm.
