Peg stepped down on March 10th, the 25th anniversary date of Epsilon‘s founding. She and seven colleagues from Earth Tech started Epsilon Associates in 1997 with the goal of avoiding repeated corporate mergers and simply providing excellent services to a regional clientele. Some of Peggy’s early projects included Fan Pier, the Boston Convention and Exhibition Center, and New Boston Garden development.

Her reputation as a go-to person for MEPA and Boston Article 80 permitting were foundational both for her career, and for Epsilon’s growing reputation as a go-to firm for securing environmental approvals for private and public real estate, energy, and infrastructure development projects. She loved working with diverse project teams of planners, architects, engineers, attorneys, developers, and local, state, and national regulators and policy makers. While no longer practicing her trade, Peggy’s mentoring of so many here ensures that her experience and wisdom will remain, in each of us.
