"The Proper Diagnosis": Oklahoma contractor sets high standards for locating and leak detection services while building his business from the ground up. Hi-Tech Plumbing & Leak Detect, Inc. was established with a focus and emphasis on leak detection and locating. Founder Jamey Mullin grew up in the plumbing industry. His father, Jim Mullin, owned a plumbing company in Tulsa and Jamey eventually opened his own subsidiary, Mullin Plumbing, in Oklahoma City in 1994. He sold that company in 2000 and launched his new venture a year later after noticing the emergence of new leak detection technology and a decided lack of companies serving the growing market.

Benji Grimes joined Drain Surgeons in Arnold, Mo., with a business degree and experience in construction and real estate development, but he was a beginner in drain cleaning and sewer inspection. His immediate focus became learning all aspects of the industry so he could manage the company his parents, Herman and Connie Grimes, purchased in 2010.
