With nearly three decades of experience transforming school infrastructure, Dan Mack specializes in helping K-12 leaders unlock significant cost savings through smart energy initiatives.
As a proud graduate of Ferris State University in Big Rapids, Michigan, Dan understands the unique opportunities facing Michigan schools. With the state's aging school buildings averaging over 45 years old, combined with Michigan's commitment to renewable energy and available federal infrastructure funding, the timing has never been better for K-12 leaders to invest in energy-saving improvements.
Dan's journey began in the United States Air Force, where he developed a foundation in precision engineering and infrastructure management. After completing his formal education, he spent a decade as an energy engineer before transitioning to business development, where he's spent the last 20 years partnering with education and municipal leaders.Proven Results
