Tim has been designing, engineering, selling, installing, and providing repair services for the ever-expanding cryogenic industry since 1988. In fact, one of the first companies he worked for was a pioneer in the cryogenic piping industry. He began as a Designer, gaining his technical foundation required before transferring into a Technical Sales role. In the following years, he continued to gain knowledge and experience by excelling in sales positions at multiple companies in the cryogenic industry. During those years in sales, Tim worked from a home office, where Donna was also home with their children. As a result, she and the family gained first-hand experience in the cryogenic piping industry. In 2009, Tim and Donna decided together that they would start their own cryogenic piping company. Their company has grown and moved, time and again. They take care of the company in the same way they take care of their own family, together, and with much love. Family comes first to Tim and Donna, which is one reason they started their own company, where they work together and with their children. When they aren’t at CryoWorks, Tim and Donna love spending time with their grandchildren, camping, and vacationing. Tim, Donna, and their entire family are always looking forward to that next family trip.
