NSSGA Board Chair Jim Nickolas said: "Mike Johnson has been a valued leader of this association for the past 11 years. He will be leaving NSSGA, as of October 11 and on behalf of NSSGA's leadership and its members, we wish him much success in his next chapter.
"Under Mike's leadership, NSSGA is in the best position it's ever been in to represent and advocate for our members. During his tenure, the association successfully implemented four successive Rocks Build America strategic plans and our membership has grown to now exceed 500 member companies within the aggregates and industrial sand industry. The events, including the AGG1 show, continued to set new records for participation and exhibit sales, reflecting the large interest and growth of our industry.
"Furthermore, Mike has assembled a team of professionals that will carry on the great work to deliver value to our member companies. The reputation and influence that NSSGA enjoys today is a testament to the work Mike and his team have done.
"Continuity is important to maintaining our success. Therefore, Michele Stanley, current executive vice president and chief advocacy officer, will serve as the interim CEO while a search process takes place to name a permanent NSSGA President and CEO."
