Costantini retires from Hoffmann Architects + Engineers
New Haven, CT According to Hoffmann Architects + Engineers, a design firm specializing in the rehabilitation of building exteriors, Deborah Costantini, AIA, senior architect, has retired. Her last day with the firm was December 19, 2025, marking 20 years of service.
Costantini joined Hoffmann in 1997 as a project manager, applying her degree in architectural engineering from Roger Williams University to building enclosure rehabilitation projects. After two years, she left her position to care for her two young sons, then returned to Hoffmann in 2007 as project architect. In 2014, in recognition of her leadership and technical knowledge, Costantini was promoted to senior architect. Three years later, founder John Hoffmann, FAIA offered Costantini ownership stakes in the company, and she became a shareholder. Since then, she has helped shape the growth and direction of the firm and has become Hoffmann’s senior specialist in roofing, leading project teams and training emerging professionals in the nuances of technical details and forensic investigation.
“Deb has been a pillar of architectural excellence, sharing her unmatched expertise in roofing solutions and innovative design,” said Erin Kesegi, AIA, co-leader of Hoffmann’s Connecticut office. “With a keen sense of precision and a consistently pleasant approach, she helped create an environment rooted in collaboration. Through her always patient mentoring, Deb has guided countless team members and strengthened our culture in ways that will endure for years to come. Her positive presence in the office will be deeply missed, but as she embarks on retirement, her legacy of knowledge, guidance, and team spirit will continue to inspire.”
Benjamin Robinson, AIA, co-leader of the Connecticut office, said, “I’ve been fortunate to work alongside Debbie for nearly 20 years. On a technical level, her meticulous attention to detail, deep proficiency, and architectural expertise have been invaluable and will truly be missed. On a personal level, Debbie’s kindness, her willingness to listen, and her thoughtful guidance have left a lasting mark on all of us at Hoffmann. I wish her joy, health, and happiness in her well-deserved retirement.”
