"I had the pleasure of working with Nick for a period of two and a half years on the Mission Trails project. During this period, I worked with him on different levels, from construction conflicts to payment applications.

Nick is a hard-working self-motivator, who invariably understands what a project is all about from the onset, and how to get things done quickly and effectively. During this period, I cannot remember an instance where he missed a deadline.

I would welcome the opportunity of working with Nick in another City of San Antonio project, should the occasion ever preset itself." (Marta Luitin, Sr. Construction Inspector, City of San Antonio)
