About Us


Jim Tubbesing founded TSC based in Dallas, Texas in 1983. Jim took a giant leap of faith as he embarked on starting his own manufacturer’s representative agency at that time. Over the years, he built a team of professionals experienced in mission critical infrastructure and information technologies, and the firm has been providing successful solutions since that time. Our senior staff consists of recognized industry leaders who sit on key technical standards committees, regularly contribute articles, and conference presentations.

After 35 years, our dedicated and hard-working founder retired on December 31, 2018. Jim’s guidance and encouragement have helped so many thrive in a very competitive environment on a day-to-day basis, and we’ve been so fortunate to have his expertise to rely on. He will be missed, but we know his retirement is the right thing at this time
