These promotions mark an important moment for the firm. Following LDa’s transition to a 100% employee-owned (ESOP) structure in 2024, the practice continues to grow and evolve—expanding its work across residential, multifamily, mission-driven, and hospitality sectors while strengthening leadership from within.
Erin Tracey and Carter Williams have long been integral to LDa’s success. As designers and leaders, they have played a key role in shaping the firm’s work, elevating its reputation, and mentoring the next generation of talent.
“Erin Tracey, our new Principal, and Carter Williams, our new Associate Principal, have long been significant leaders and creative forces at LDa,” said Treff LaFleche, Co-Founder of LDa Architecture & Interiors. “Their contributions have helped sustain and expand our reach and reputation across both architecture and interior design. Their ability to manage all aspects of the design and construction process makes them trusted partners to clients and collaborators, as well as important mentors within our studio. Erin and Carter represent the kind of seasoned, inspiring leaders we are proud to elevate as we look to the future of our newly employee-owned firm.”
“Erin and Carter have each emerged as design and thought leaders across our markets, from custom single-family homes to multifamily housing and hospitality,” added Douglas Dick, Co-Founder of LDa Architecture & Interiors. “Their work has been recognized in publications including Boston Home and New England Home, as well as through awards and industry engagement. They have led design seminars on topics such as integrating art into the home, aging in place, and accessibility, and are currently leading projects across metro Boston, New York City, Cape Cod, New Hampshire, and Vermont.”
