“Our goal as a company has been to provide services to assist our clients and employees toward achieving their respective goals. When all parties work together the reality is that all parties benefit.”
In 1980, Guy graduated with a Bachelor of Science degree from Texas A&M. Upon graduation, Guy started in the mechanical contracting business with The Emde Companies where he was exposed to working with high rise buildings, specialized industrial and medical facilities. At Emde, Guy learned the importance of good business values and building relationships. New opportunities arose when he joined Gowan Inc., a family owned sheet metal company that decided to expand into the mechanical contracting business. Here, a sense of tradition with employees was well founded as it was common for second and third generations to be employed. Upon the sell of Gowan Inc. in 1991, Guy founded Infinity Systems, Inc. Initially the goal for Infinity Systems was to establish a small but financially strong company for a group of families to work together, prosper, and expand developing friendships as business relationships. Today, Infinity is much larger than anyone anticipated. But more important than our size is we are attaining our original goals: our employee families are prospering and we are working on generations. We still maintain old friends but we have new friends and clients that are expanding and prospering as well.
Guy and his wife Kelly have two college age children and enjoy time away at their lake house in the Hill Country. Community near and far are their passion. Locally, they are active in their church and community. Abroad mission work with Grupo CEO in Fortaleza, Brazil has led to eye opening experiences and needs. Recently, Guy decided to form a new 501 © 3, Hands with Nails, Inc. with the hope to be even more successful at efficiently helping those in need both locally and abroad.

DENIS NOLAN
“I understand that in construction and in life, sometimes things don’t go as we would like them to. I believe that it is at those times, that how we respond to the situation determines whether we are successful or not.”
Denis was born and raised in Bayonne, New Jersey. As the son of a third generation plumber, Denis knew from an early start that a career path in the construction industry was ahead of him. After a couple of years of merchant marine office training school at Texas A&M Galveston, Denis returned to New Jersey and graduated from Kean University with a Bachelor of Science in Industrial Technologies. While attending Kean University at night, Denis gained priceless experience working for a general contractor and two mechanical contractors during the day to put himself through school. Upon graduation, Denis returned to Houston with his wife Laurin, whom he had met during his time at Texas A&M Galveston, and went to work for Letsos Company as an estimator and project manager. In 1999 Denis came to work for Infinity Systems and became a partner in 2003. Denis has completed numerous HVAC related courses including estimating from Estimation, Inc., Trane Air Conditioning Clinic, and Carrier Technical Development Program to name a few. When asked, Denis is quick to answer that his favorite part of the construction industry is the relationships he has made during his twenty years in the business. His philosophy on business: people like to do business with their friends; owners, general contractors, subcontractors and vendors should all be treated with the same respect that I like to be treated with. Denis enjoys hunting, fishing and exercising. After being inspired by his wife who completed her first marathon in 2008, Denis completed his first marathon in January 2009. Denis and Laurin have two junior high aged daughters.
