Alan has served as the Executive Director of the Tennessee Concrete Association since 1998. In July of 2016, Alan was recognized by the Tennessee Society of Association Executives as their 2015 Association Executive of the Year. He regularly teaches concrete industry professional courses across the US and served as an Assistant Professor at Middle Tennessee State University for the Concrete Industry Management program for the 2010-2011 academic year. He developed and teaches a class on Concrete Construction Sustainability for the “Concrete” MBA program at MTSU.
He has been deeply involved with pervious concrete for over a decade and regularly places pervious concrete both for TCA demonstration projects and commercial projects where he is asked to assist and train contractors learning about the correct placement of pervious concrete. Alan holds the NRMCA Pervious Concrete Craftsman certification and is a co-author on several research publications relating to pervious concrete, as well as other concrete topics. He works closely with universities in Tennessee to design and direct research relating directly to current concrete issues, and TCA publishes this research in Tennessee Concrete magazine on an ongoing basis.
As a firm believer in lifelong learning, he completed his Masters of Business Administration degree in May of 2004 from Jones International University. In November of 2006, Alan became a LEED Accredited Professional through the U.S Green Building Council and in January of 2007 Alan earned his Certified Association Executive (CAE) designation, a certification earned by less than 5% of all association professionals. He currently holds 15 technical and professional certifications related to concrete, construction and association management.
Alan was honored to receive one of the prestigious Kodak American Greenways Awards in 2004 for his efforts in making the Count on Concrete bike ride across America a success. He was honored with the 2010 Tennessee Sustainability Award by the Tennessee Environmental Council, and has twice been honored with the TCA President’s Award (2008 & 2013).
In April of 2016, Alan received the Concrete Sustainability Award from the American Concrete Institute “for significant mentorship of the concrete community in the field of sustainability and exemplary outreach to those in the public, private and social sectors improving recognition, understanding and appreciation for the sustainable benefits of concrete as a building material.”TCA has been named by the National Ready Mixed Concrete Association as the State Association of the Year three times under Alan’s leadership, with the most recent award coming for 2015.
