Stone Environmental board sees change in leadership

MONTPELIER — John Hanzas has been named president and Michael Winchell vice president of Stone Environmental’s board of directors, effective July 1. While stepping down from their current executive positions, President and founder Christopher Stone and Vice President David Healy will both remain at Stone providing senior executive and technical consulting support, as well as serving on the board.

Hanzas and Winchell are both longtime Stone veterans and leaders in their respective fields. They serve on Stone’s senior management team, and are well positioned to take on these new executive roles, as well as continue to lead Stone’s Agrochemical Fate and Exposure and Environmental Modeling teams.

“John and Mike bring experience and complementary talents that will take Stone to the next level of quality, innovation, and responsiveness that our clients expect to see,” said Stone. “They are supported by an amazing team of professionals who are passionate about the work they perform and make Stone a great place to work. Personally, I am looking forward to contributing on a number of different levels as Stone Environmental moves onto this new chapter.”
