Byrne succeeds Gregory A. Hayes, who is stepping down from the role and will focus on his private client practice. Hayes served eight years on the firm’s Executive Committee, including three years as Managing Partner.
“Leading this firm has been one of the great privileges of my career. We have made tangible progress growing the platform, strengthening our practices, and investing in markets where our clients need us most. Mike brings the relationships, judgment, and vision to continue that momentum. I leave this role with real confidence in where we're headed,” said Gregory A. Hayes, former Managing Partner of Day Pitney LLP.
Hayes will remain involved in the firm’s strategic growth initiatives in addition to his private client practice.

Day Pitney is in a position of strength, and we will build on that success through a deliberate strategic growth plan, while being attentive to the market dynamics and technological shifts in the legal industry,” said Michael P. Byrne, Managing Partner of Day Pitney LLP.

Since spring 2023, Day Pitney has added 40 partners, including 21 lateral hires and 19 partner promotions, expanding its presence in Boston, Florida, New Jersey, and Washington, D.C.
As Managing Partner, Byrne will focus on a partnership-driven strategic growth plan and the implementation of emerging technologies, including artificial intelligence. He also plans to conduct a structured listening tour and strategic review to align the firm’s priorities.
