The CEO of Boston-based Shawmut Design and Construction announced yesterday that he will retire next summer.

Tom Goemaat will retire effective July 1, 2015. He will be succeeded by current President Les Hiscoe. Over the next six months, Goemaat will work with Hiscoe to ensure a seamless transition. 

"It feels like the right time for me to step away," Goemaat said in a statement.  "After over 15 years of leading this company, it’s time to let the next generation of talent take Shawmut into the future.  I am excited to hand the baton to Les, who has been a wonderful partner to me and has the necessary vision and energy to continue driving Shawmut forward."

Goemaat has been with the national construction management firm for more than 20 years, serving as CEO for the past 15 years. Under his leadership, Shawmut has grown into a billion dollar, 100 percent employee-owned firm;  opened eight new offices around the country, including Providence, New York, and Los Angeles; and expanded into new market sectors including public work and healthcare in New England, academic and museum work in New York, and sports venues and hotels nationally. Overall, the firm has nearly doubled in size since 2010.

Hiscoe has more than 25 years of experience in the construction industry, with 17 years at Shawmut. Hiscoe has been instrumental in the growth of the company’s New York office, expanding its retail business nationwide and founding the academic group which has completed projects at Yale University and Columbia University. 

"We are extremely thankful to Tom for all the years he put in at Shawmut.  Tom has been a great CEO and friend for over 20 years," Shawmut Founder and Former Chairman Jim Ansara said in a statement.  "When Tom came to us with his intentions, it was an easy choice to name Les Hiscoe as his successor.  Les has been a valuable member of our executive team and will be a great leader as we enter a new era at Shawmut."
