Our Name
BTL Architects, Inc. is the new name for Gustitus Group, Inc., the company founded by Delph Gustitus in 1995. Throughout its history, the company has focused on extending the useful lives, and improving the performance of, buildings throughout Illinois - bringing them back to life.
“Since starting the company in 1995, one of my core principles has been to be in service. Not just being a service business; but to really serve others.
Working with that principle over these many years, I have discovered that in serving my clients, I am also serving their buildings and the communities in which those buildings are located. In a small way, my work touches many lives.
Consequently, I treat each building and project as if it were my own. I have a deep commitment to the clients I serve, and to the success of every project - and I know that my involvement is making a difference.”
