Tennessee Concrete Association

Building Concrete Solutions for Tennessee Communities

TCA leads the concrete industry in creating sustainable value for members and customers through Advocacy, Education and Market Development.

What We Do

The Tennessee Concrete Association – TCA – was formed in 1986 (originally known as the Tennessee Ready Mixed Concrete Association) with the primary purpose of promoting the increased use of ready mixed concrete in Tennessee. Today, we have 38 ready mix producer member companies representing approximately 70% of the annual ready mix production in Tennessee. The TCA is organized as an IRS 501 C (6) non-profit trade association.


The association is governed by a Board of Directors elected annually by the membership. The board includes eight ready mix producer members, three associate members and one affiliate member representing each class of the TCA membership.

Our major activities include:

  • Promotion and marketing of concrete products to the construction industry and other stakeholders in Tennessee

  • Administration of several national certification programs, including:

    • American Concrete Institute’s (ACI) Concrete Field Testing Technician Grade One, Concrete Flatwork Finisher and several more

    • National Ready Mixed Concrete Association’s Pervious Concrete Technician and Installer, Certified Concrete Sales Professional, and Concrete Technician Level Two courses

  • Liaison with the state of Tennessee on behalf of member companies with regard to concrete specifications, environmental regulations and general business issues

  • Liaison with Tennessee colleges and universities to provide up-to-date information on concrete products, technologies, and processes

  • Research partnerships with Tennessee universities to improve concrete products and installation processes

  • Scholarship and program support for the Concrete Industry Management major degree program at Middle Tennessee State University

  • Publish Tennessee Concrete magazine three times annually

  • Host educational and networking events at the beautiful TCA Campus in Nashville

  • Hold our Annual Concrete Conference, Annual Concrete Design Awards competition, Annual High School Concrete Essay competition and more!

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.
