Michael Bertoncini

Michael Bertoncini was inspired to join Griesenbeck in 2017 after seeing the family atmosphere and open door of leadership. "I saw the way they conducted business and knew right away that this was the place I wanted to be."

After being promoted to Director of Estimating & Pre-Construction in 2025, it's clear that Mike has a vision for the team as well. What's one thing he hopes Griesenbeck achieves in the next 10 years? "Opening the Coastal Bend office."

When asked about a lesson he would say still guides him today, Mike responded, "Bad news is better than no news. I learned early on that if you are always honest and upfront about a situation, people will respect you more. We are also a deadline-driven industry, so organization is key in being successful."

Mike has several projects he is proud of after nearly a decade at Griesenbeck. A standout? The upcoming "MD Anderson Clinical Services Building" comes to mind. "This is our largest wall protection project to date as well as over 30 McKEON fire and smoke rated doors. We worked on the design of the fire doors for over a year, and to see all the hard work our team put into this project finally come to life" is very rewarding.

Q & A

What's your most memorable "oops" moment in your early career?

"At Bridgeland High School, we were installing wall protection in a four-story atrium. When installing this type of wall protection, the building must be fully dried in and temperature-controlled which means gas-powered equipment cannot be used. Due to the size of the space and difficulty to install, a special battery-operated piece of equipment was needed... and I did not account for that specialized piece of equipment."

"Success in construction begins long before the first shovel hits the ground."
