Patrick J. Sullivan founded Sullivan & Associates, Inc. in September, 1995. As a former Level III examiner, API-510 Pressure Vessel Inspector and an API-653 Storage Tank Inspector, he has experience in all facets of nondestructive testing. He worked as an NDT inspector for years before venturing out on his own. His business acumen, combined with his expertise and knowledge of all phases of NDT, lead him to the decision to start a business which catered to diverse companies, offering them the highest levels of NDT service, the latest and most comprehensive technology and meticulously completed reports. Pat accomplished this initial endeavor and has since brought his company to the forefront of the NDT community. Through hard work and long hours, he has made Sullivan & Associates a business that both his clients and employees can appreciate.

Today, we have some of the most highly trained inspectors and provide services for businesses and governments throughout the United States and around the globe! Our technicians have many years of experience in their specialized fields including ASME, API, AWS, AWWA, ANSI, ASTM, ABS, MIL-STD, NAVSEA, NBIC and various proprietary client certifications.
