Learn About SSi of Northwest Arkansas


SSI Incorporated was founded in 1969 by Leo Anhalt, an exemplary leader in our industry, and we're proud to say we have been in operation ever since. SSI provides design-build, pre- and post-construction, and construction management services for Arkansas and our surrounding states. Early on, the company spotted opportunities for growth in the northwest region of the state, so we expanded operations with an office in Springdale.


In 1984, the Springdale branch officially became a standalone entity to directly serve clients in the Northwest Arkansas region. In January of 2023, Trent Hanna, an experienced professional in the industry, stepped in as Managing Partner of SSI of NWA. He's on a mission to become the largest General Contractor in the region, with a team of passionate and skilled professionals on his side.

More About
Our Founder

SSI wouldn’t be in existence if it weren’t for the vision and leadership of Leo Anhalt. Leo has been co-owner, President, and General Manager of SSI Incorporated since its inception. Over the years, Leo has been an integral part of SSI and the construction industry. He helped establish an Arkansas Chapter of Associated Builders and Contractors (ABC). He served on the steering committee for the chapter's formation in 1974 and was an active member for many years. He served 14 years on the State Chapter Board of Directors and was President of the Chapter in 1976 and 1985. In 1980, he was honored as the Most Valued Member since the beginning of ABC in Arkansas. He was ABC Man of the Year in 1985. In 1992, he was honored by the Arkansas Chapter with the Distinguished Service Award. 

On the national level, Mr. Anhalt served on the following ABC Committees: the National Education Committee (12 years, four as chairman), the Construction Industry Cost Effectiveness Committee, the By-Laws Committee, and the Metal Building Council (chairman). He has achieved the Presidential Level in the Beam Club for membership recruitment. He has served on the National Board for seven years, was Region III Vice President for three years, was President-elect in 1993, and National President in 1994. He has been a member of the Board of Trustees and Secretary of the Construction Education Foundation and has served as Trustee of the Construction Legal Rights Foundation. Mr. Anhalt currently serves on the Board of Directors for Benefit Bank, the Gregory Kistler Treatment Center, the Subiaco Foundation, the Fort Smith Regional Council, and the Fort Smith Regional Chamber of Commerce. 


As you can imagine, we are honored to have the wisdom and legacy of Leo Anhalt influencing our company. As SSI of NWA continues to grow, we will always be proud of our strong history.
