Our History

O.C. Unbehagen, Sr. founded Unbehagen Construction in 1947 but long before that he was working as a general contractor in the island city building residential and commercial structures – many of which are still standing today.


O.C., Jr. grew up in the industry working with his father. He attended Texas A&M University in College Station then returned to Galveston and again assisted his father in running the family business. O.C., Jr. became an owner in several commercial construction ventures  but in time he re-established Unbehagen Construction, making one of the most successful general contractors in Galveston County. During his career O.C., Jr. worked on such renown projects as the Bob Smith Yacht Basin Club House, the San Luis Hotel, Casa del Mar and Hospital Galveston (the Texas Department of Criminal Justice's health care facility on the UTMB campus).  


For nearly four decades, Mike Unbehagen, O.C., Jr.’s son and TUCON CEO, has worked to master the art of industrial and commercial construction. His portfolio includes industrial facilities, city, county, state and federal government facilities, as well as, religious, educational and medical construction, as well as high-end residential work. It’s a career that has taken him from field work to oversite and management of numerous multi-million dollar projects and now with the founding of TUCON, LLC he is passing along his knowledge and experience to the next generation of Unbehagens.  

Mike Unbehagen, CEO

Since 1947 the name Unbehagen has been synonymous with quality construction. And for the past 40 years, Mike Unbehagen has built upon  that legacy by mastering  the art of industrial, commercial and civil construction. His portfolio includes industrial, city and county municipalities, federal and state government, religious, educational and medical projects, as well as high-end residential work. It’s a career that has taken him from field work to oversite and management of numerous multi-million dollar projects.


Mike’s career has included work for major Houston-area general contractors and two member institutions of the Texas Medical Center. For nearly 15 years prior to incorporating TUCON Mike worked for a major area contractor overseeing the company’s commercial construction division.


Mike’s extensive knowledge of the construction industry and his passion for his work are integral to the TUCON organization. It’s his solid business ethics and desire to ensure successful outcomes for all parties that define TUCON’s business philosophy and have proven invaluable in today’s complex construction environment.
