Gonzalo Bernal Diaz Leal
Sole Owner
I have 25 years of high end residential design build management experience. I met Gonzalo Diaz on the largest project of my career. The design and implementation of the work was at the highest level. Gonzalo was focused and met all challenges without complaint.
Now that I am retired, I've been fortunate to again benefit from his dedication to his craft on my own home's foundation and associated hardscaping. I am excited to hear Gonzalo Diaz and his team have formed GBD Concrete. My experience was on-time, on budget, dependable, professional and reasonably priced. I plan to use them again and I recommend GBD Concrete to anyone wanting concrete done right!
