Almost every week, it seems that a new "low voltage" contractor opens their doors. From alarm companies to electrical contractors, everyone seems eager to enter this marketplace. What makes Dominion Design & Integration different from the rest? --Expertise-- Dominion Design & Integration was founded by Trey Hellums, an electrical engineer who holds a professional engineering license from the state of Texas. Before founding Dominion, Trey worked in the industrial engineering field for over 10 years automating chemical plants and other large industrial facilities. His experience in design, project management, and construction are unrivaled. Builders need experts like those at Dominion to ensure customer satisfaction and well-wired homes.--Professionalism-- Dominion Design & Integration strives to project a professional image that is uncommon among many subcontractors in the homebuilding industry. Employees of Dominion wear uniforms and arrive at jobsites in marked company vehicles. Customer satisfaction is the number one goal. We never forget that it is a privilege to work for some of the finest homebuilders in San Antonio.
