Dave Holls is a 2016 graduate of the Mike Ilitch School of Business at Wayne State University with a Bachelor of Science in Business Administration (BSBA) degree in a concentration of Global Supply Chain Management, with a minor in Public Relations.  He also received both an Associate in Business Administration (ABA) and an Associate in General Business (AB) degrees from Henry Ford College. Mr. Holls joined Trinity in 2009 as a driver.  He worked in each of our divisions, and became experienced with all aspects of our operations.  While still driving, he began assisting management with operational support initiatives, which led to him into a supervisory role.

In 2013, Dave took over management of our Roseville school bus terminal and six months later took on a second terminal in Hamtramck, simultaneously overseeing all facility, personnel, and maintenance operations at both locations.

In 2015, Dave was promoted to the position of Regional Operations Manager, overseeing the management and direction of all school bus operations for the company.  He is strongly focused on  technology, and uses these tools to increase operational efficiencies whenever possible.

Before joining Trinity Transportation, Dave had a 10 year real estate career and was actively involved with his local real estate board, chairing numerous committees and being nominated for the board of directors.
