John Castilla


The construction industry has always interested John. As a teenager, he worked summers alongside a neighbor, who served as a general superintendent for several large-scale commercial construction projects. The experience and mentorship motivated him to enroll in his high school’s building trade course, where eight students designed, estimated and constructed a single-family home – selling it for a profit later that year. Since that time he’s never looked back. He spent 28 years working in various capacities for a Fortune 100 national contractor in the healthcare, life sciences, higher education and corporate office markets. Most recently he worked in commercial real estate, overseeing the development and construction of projects in the Houston area. At Welty, John will help drive growth in the Texas market.

Words to live by:

Your character and integrity represent who you are. When you have a tough decision to make, think of how you would explain your choice to your children; you’ll make the right choice every time.
