Michael Agresti, MST, CPA

Michael Agresti is a Partner in LSL’s Tax & Advisory department with a knack for bringing structure to financial chaos. Messes don’t worry Michael—he sees them as puzzles to solve. Whether it’s untangling a complex compensation package, cleaning up multiyear reporting issues, or guiding a client through a business transition, his natural ability to organize and strategize takes over until everything makes sense again.

Since beginning his career in 1998, Michael has worked with entrepreneurs, real estate investors, manufacturers, healthcare professionals, attorneys, and construction companies—each with unique challenges, but all sharing one goal: to minimize tax impact while building long-term financial strength. His clients often have closely held businesses, high-net-worth profiles, or both, which means their needs extend far beyond basic compliance. That’s where Michael thrives.

At LSL, Michael focuses on clients with complex planning needs, helping them navigate everything from retirement strategies and entity structuring to succession planning and tax controversy. He’s represented clients before tax authorities, supported business acquisitions and sales, and consulted on strategic planning initiatives to align financial outcomes with business goals. His clients appreciate his practical advice, his ability to simplify the technical, and his commitment to being available when questions arise—whether they’re personal, business-related, or a little of both.

Off the clock… Michael stays just as active outside the office. He plays in a weekly roller hockey league and enjoys unplugging on road trips with his kids, exploring new places in their camper. A lifelong baseball fan, he’s on a mission to visit every Major League Baseball stadium in the country.
