Top 60 accounting firm Katz, Sapper & Miller (KSM) announced Monday its formal entry into the Chicago market with the addition of MichaelSilver, a Deerfield, IL-based advisory, tax, and assurance firm serving clients for more than 80 years.
Financial terms of the deal, which takes effect on July 31, weren’t disclosed. MichaelSilver brings 60 professionals and 14 partners to KSM, including co-managing partners Larry Isaacson and Jennifer Barliant, who will continue to lead KSM’s new Chicagoland office. Eligible MichaelSilver employees will become employee owners through participation in KSM’s employee stock ownership plan.
MichaelSilver will be fully integrated into KSM as its Chicago regional office and will assume the KSM brand over the coming months.

“We are excited to welcome MichaelSilver to the KSM family. MichaelSilver was a natural fit for our firm—not just because of its depth of talent and complementary services, but because of our shared culture and values,” Tim Cook, CEO and president of Indianapolis-based KSM, said in a statement. “Given our existing team of a dozen remote employees and many valued clients in Chicagoland, establishing a dedicated KSM office in the region will further solidify our presence in the Windy City. This move strengthens our relationships, opens the door to new opportunities for growth, talent, and impact, and supports many of KSM’s strategic goals.”
Founded in 1944, MichaelSilver provides tax, accounting, assurance, and consulting services to a diverse mix of middle-market clients, including those in the automobile dealership, fleet management, high-net-worth, manufacturing, professional services, and real estate sectors. MichaelSilver’s expertise in trust/estate, international tax, outsourced finance and accounting, valuations, and transactions complements many of the services KSM offers its clients, a July 28 media release states.
“Joining KSM marks an exciting new chapter in MichaelSilver’s 80-year-plus history. From the start, we recognized in KSM a shared commitment to forward-thinking strategies, employee development, and values that mirror our own,” Barliant said. “We’re excited to leverage KSM’s expanded resources and collaborative spirit to continue delivering exceptional results for our clients and new opportunities for our team.”
Isaacson added, “We approached the decision to join KSM with great care, knowing how critical it is to align with a firm that reflects our principles and aspirations. KSM’s people-centered culture, leadership vision, and emphasis on employee development made that alignment clear. As we become KSM’s Chicago regional office, we look forward to building on MichaelSilver’s legacy and shaping a strong future together.”
KSM’s most recent M&A deals occurred last year with Shanholt Glassman Klein Kramer & Co. (SGKK) in New York City and Cassady Schiller in Cincinnati.
