DTyroltAs Dunn’s top executive, David’s focus is to maintain and strengthen Dunn’s core principles—to attract and retain good team members; build strong relationships; offer excellent quality service; develop niche business markets; invest in good equipment; and maintain a safe work environment.


David graduated from St. Teresa High School and earned a bachelor’s degree in management from Indiana University. His relationship with Dunn began with his father, Frank Tyrolt, retired chairman of Dunn Company, when he was a child, but officially started during the summers from 1986-1991 while he was in high school and college.


After college, David worked in the banking industry until 1994, when he returned to the family business. He worked closely with his father and Bernie Naber, who served as mentors. He led the Pavement Maintenance Unit until 1996 and worked in the Base Stabilization Unit until 1998, when he was named Vice President. He became President and CEO in 2002.


David is very active outside Dunn Company and serves on the boards of several industry associations. He also volunteers with many local community service organizations.


He enjoys spending time with his wife and three children.
