In 1974, Gene Nolen and three other partners established the first plant CEW Enterprises located in North Vernon, IN. 

In 1979, GTR Enterprises was established in Edinburgh, IN. With Gene’s can-do, never-give-up attitude, GTR Enterprises experienced tremendous growth with many customers including Toshiba. The GTR company name was coined in honor of his son Greg, his daughter Tammy, and his wife Rose – hence the name GTR Enterprises, LLC. 

Along with his passion for learning, innate understanding of plastic injection molding tooling design, superior processing skills, and innovative spirit, Gene Nolen helped develop the first non-painted passenger service unit panels for the Boeing 777.

By 1991, GTR Enterprises and CEW Enterprises merged to form MANAR. Over the next several years MANAR would acquire Tennplasco located in Lafayette, TN; Key Manufacturing located in Madison, IN; ECA Enterprises located in Edinburgh, IN; and a global partner when MANAR-Reliance Joint Venture was established located in Shenzhen, China.

On March 31, 2016, Gene Nolen became the sole owner of MANAR. Less than a year later, MANAR became an Employee Stock Ownership Plan (ESOP) company and today is 100% Employee-Owned.  MANAR Chief Executive Officer (CEO) Gene Nolen was a passionate leader who was sincerely grateful for his employees and wanted to reward them for their hard work and loyalty.
