Haygor Instrument and Company, Inc.
Haygor Instrument was founded in 1973 in Pasadena, TX and became a Texas Corporation in the late 1970s. Today, the company is proudly owned by Allen Bishop. In 1981, George Bishop moved Haygor to its current location near Hobby Airport in Houston, TX. After nearly five decades of unwavering dedication, George passed the torch to his son Allen in 2017. Allen, having grown up immersed in the business, continues his father’s legacy with pride and vision.
Once a small job shop, Allen Bishop has transformed Haygor into a full-service instrumentation facility supporting industries such as petrochemical, oil and gas, cryogenic, and medical, among others. Even with exponential growth over the past 50 years, Haygor remains committed to its small-business mindset, fueled by the same passion, integrity, and personal service that sparked its beginnings.
