Leadership

Mike has led Blach Construction since 1989, taking over the helm of the business at 26 upon the untimely passing of his father and founder, Michael S. Blach.  During Mike’s tenure, Blach has grown tremendously and is an established leader in the California construction industry.

As chairman, Mike provides strategic guidance to the firm. He enjoys mentoring younger team members and representing Blach in several industry, philanthropic and civic organizations, always promoting the Company’s positive values and culture.

Mike started at Blach as a teenager in 1979, first working five summers in the field, and then through college as a project engineer/manager and estimator.   After earning his MBA, he returned to Blach full-time as an estimator/project manager where he led numerous successful projects until he took over management of the Company.

Dan joined Blach in 2001 and by the time he became President in 2017, he had made tremendous strides in developing the firm’s operations infrastructure and service offerings. Under his leadership, Blach expanded into new markets and geographical areas and has been recognized consistently as a Top Contractor by Engineering News Record (ENR) of California and a Best Place to Work by Blach employees, as reported in the Silicon Valley Business Journal. These awards are on top of several notable project and safety awards from the likes of the Associated General Contractors, ENR and the Silicon Valley Business Journal, to name a few.

Combining his thorough command of construction with an unprecedented degree of foresight, Dan is committed ensuring Blach employees have the support they need to enjoy success and expand their expertise while finding new and innovative ways to provide greater value to clients.  He is a highly engaged, strategic and decisive leader who was aptly named one of Silicon Valley’s “40 under 40” in 2007 and subsequently “COO of the Year” in 2017.
