Byrne Named Managing Partner of Day Pitney

On Apr 7, 2026

Michael P. Byrne has been elected managing partner of Day Pitney LLP, which makes its New Jersey headquarters in Parsippany. He succeeds Gregory A. Hayes, who will focus exclusively 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,” Hayes said. “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.” Hayes will remain involved in the firm’s ongoing strategic growth initiatives in addition to his private client practice.”

“We are incredibly grateful to Greg for his leadership and his many contributions to the firm’s growth and success,” said Byrne. “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.”

Byrne has served on the firm’s executive committee for three years and, before that, was the chair of the firm’s real estate practice for over 10 years. He transitions to the role of managing partner at a moment of significant momentum for the firm. Since spring 2023, Day Pitney has added 40 partners, including 21 lateral hires and 19 partner promotions, deepening its presence in key markets, with significant expansion in Boston, Florida, New Jersey, and Washington, D.C.

As managing partner, Byrne will initially focus on two core initiatives–a deliberate, partnership-driven strategic growth plan and the implementation of innovative and emerging technologies, including artificial intelligence. In his first months as managing partner, he will also conduct a structured listening tour and strategic review designed to align the firm around clear priorities and opportunities for growth.

Byrne will continue his commercial real estate transactions practice, representing a broad range of clients on real estate finance transactions, acquisitions, dispositions, leasing, development, and joint ventures. His clients include life insurance companies, banks, pension funds, investment banks, commercial lenders, corporations, private equity funds, religious organizations, utility companies, and high-net-worth individuals. He has been ranked in Chambers USA for Real Estate in Connecticut and named to the Best Lawyers® in real estate law.
