William (Will) L. Mack has been an integral part of LeChase since 1993. In 2015, he was named president, assuming responsibilities for the firm’s organizational structure, strategic implementation, and customer and community engagement. In 2024, Will was appointed vice chairman, continuing his role in executive management and on the Board of Directors. He assists the Chairman and CEO on direction and growth of the organization, and the President on overall company performance.

A third-generation construction professional, Will entered the business at a very young age – journeying through the industry’s ranks during school breaks and later as a field engineer during college. Prior to joining the LeChase team, he worked at Edgewater Construction Co. and William J. McNeary Development Co. Will’s career of diverse expertise in project management, finance, real estate and business strategy now brings a wealth of knowledge and proven success to LeChase, and the skills he’s worked tirelessly to acquire are now used in planning the firm’s “get good work” strategy.

Will is actively involved with several affiliations, both regionally and nationally. He currently serves on the board for the Mary Cariola Center. He is a former board member for Builders Exchange of Rochester and the Rochester Area Foundation for Multiple Sclerosis, as well as a former member of the Village of Fairport Planning Board. In 2015, Will served alongside Bill Goodrich, LeChase CEO and managing partner, as co-executive leader of the American Heart Association’s 2015 Rochester Heart Walk, an annual community event that celebrates heart health and a commitment to take a stand against heart disease.

Will’s education includes a B.S. degree in finance from Siena College. Additionally, he has participated in various trade- and industry-specific programs and training.

As a leader, Will focuses on building strong partnerships with LeChase’s customers, employees and communities through safety, quality, innovation and values.
