Okemos, Mich. – The Board of Directors of the Michigan Concrete Association (MCA) is pleased to announce an upcoming leadership change that will take effect at the beginning of 2024. The current Executive Director / CEO of the association, Dan DeGraaf, has stated his intention to retire from the post at the end of 2023, a position he has held since 2006 with the Michigan Concrete Paving Association (MCPA) and continued through the 2009 merger of MCPA with MCA. Dan has been in the construction industry for 50 years, serving the concrete association in Michigan for the last 23 years and has held many positions with concrete paving contractors throughout the U.S. in the 22 years prior to that. In retirement, Dan plans to spend more time with his wife, three children and their spouses, and four grandchildren and hopes to spend a little more time on the golf course.
