The Hensel Phelps’ board of directors promoted Tom Diersbock, a 28-year veteran of the company, to executive vice president. Diersbock most recently led Hensel Phelps’ Pacific region and now oversees operations in Southern California, Northern California and the Pacific regions.

Replacing Diersbock as regional vice president for the Pacific is Jon Tseu, whose diverse 26-year career with the organization spans multiple locations. Most recently, Tseu spent the past seven years as an executive in the Pacific region and is poised to continue leading Hensel Phelps’ Pacific team.
