    Mr. Adewale is a leading voice in the engineering profession, regionally and nationally. He served on the board of directors for the Engineers Club of St. Louis from 2010 to 2011, is currently the Vice Chair of the Engineering Division of the State Board of Architects, Engineers, Land Surveyors and Landscape Architects (APELSLA), and is a member of the board of National Council of Examiners for Engineering and Surveying (NCEES).  In 2011 he served on the ABET accreditation committee responsible for University of Missouri – Columbia’s Engineering Program-accreditation.  Mr. Adewale is also an active member of the State Design Alliance, American Council of Engineering Companies (ACEC), where he serves on various committees, American Society of Civil Engineers (ASCE), Institute for Transportation Engineers (ITE), Missouri Society of Professional Engineers (MSPE), National Society of Professional Engineers (NSPE), National Society of Black Engineers (NSBE), Associated General Contractors (AGC), St. Louis Council of Construction Consumers (SLCCC), and the Engineers Club of St. Louis.  In 2013, the Missouri Society of Professional Engineers (MSPE) selected Abe Adewale PE as the Engineer of the Year.

    Mr. Adewale has been married to Nicole, a civil engineer, for twenty years. They have four daughters ranging in age from 8 to 19 years old.  The oldest daughter is a second-year architectural student at the University of Kansas (KU).  He often jokes that he would need to work until he’s 80 to put them through college and pay for four marriages. All jokes aside, he relishes being a father and holds his children in the highest regard.

    Under Mr. Adewale’s leadership, the company has grown from a staff of 2 to over 80 in 18 years. It has become a formidable engineering powerhouse in the Midwest, providing services on some of the region's most significant and highest-profile public projects.  In 2007, Abe was awarded the Central/Midwest Region’s Ernst & Young Entrepreneur of the Year for outstanding entrepreneurship with Professional Services.  He has led the transformation of ABNA into a full-service Civil engineering operation offering services in Aviation, Rail, Highways, Bridges, Water/Wastewater, GIS, Surveying, and Construction Management.

This transformation also includes ABNA’s addition of a Heavy Civil General Contractor Division servicing such clients as St. Louis Public Schools and Salvation Army. 

    Mr. Adewale’s community involvement includes the St. Louis Science Center, the Chair of the National Society of Black Engineers (NSBE) Scholarship Fund, and the Rotary Club of St. Louis. For the last ten years, he has served as a judge and sponsor of the St. Louis FIRST Robotics Competition. He also employs and mentors high school and college interns during the summer to expose them to surveying, engineering, CADD and general office operations.

    For years, he has leveraged his position throughout various organizations to develop strategies to promote the engineering profession, and the civil engineering profession in particular, to enhance the number of young people pursuing the profession.  To that end, Abe is tremendously honored to be recognized by MSPE and hopes that it will continue to inspire students of all backgrounds to pursue engineering and build a better community.
