Bob Grace's 42 year career in commercial industrial diving originated during his 6 year enlistment as a United States Navy Deep Sea Diver. Five months after his honerable discharge from the Navy, he completed his first commercial job at an electric utility plant in Cleveland, Ohio. He provided expert underwater welding and a thorough inspection of all the electric utilities underwater structures. Grace Diving's client base quickly grew to include ODOT, electric utility plants, national railroad companies, and refineries, all taking advantage of his ethics and expertise gained during his service and tenure as a US Navy Diver. In the early 80's Bob became a member of AREA which then changed to AREMA (American Railway Engineering and Maintenance-of-way Association). He works with Committee 10 (bridge and structures) and Committee 24 (Railroad Education) for AREMA. Bob co-authored the AREMA BRIDGE AND STRUCTURES MAINTENANCE HANDBOOK which is used industry wide by all major and shortline railroad companies. In the mid 80's, Bob was appointed to the Great Lakes Zebra Mussle Task Force representing Centerior Energy.

Bob was the founder of the Browns Backers, and to this day is still the Chairman. In 1995 after Art Modell moved the Browns to Baltimore, Bob Grace was asked by Cleveland Mayor Michael White to lead the crusade as Chairman of the "Save Our Browns" -  to save and bring the Cleveland Browns back to Cleveland. Bob led a back breaking campaign against the NFL that ultimately brought the team back to Cleveland, Ohio where it belonged. In 2000, Bob was sponsored by Federal Judge, Christopher Boyko, to attend the FBI Citizens Academy of Cleveland.

   Tony Grace early in his diving career working on Traveling Screen repairs


As a child, Anthony had a strong attachment to his father’s career in commercial diving and his service experiences as a US Navy Deep Sea Diver. At the age of 10, Anthony began working with his father, traveling with him to various work sites, and observing the use of equipment and diving practices and procedures that were used on a daily basis. At age 12, Bob let him dive on open water dives videotaping the diving operations. Tony was educated and trained by his father in the use and maintenance of diving helmets, diving equipment, and the basic principles of the US Navy Diving Manual. Tony observed commercial diving for several years until his first experience as an onsite tender/diver at the age of 15. His interest in his father’s Navy career as a Special Forces Deep Sea Diver intrigued him to the point of adopting that training and work ethic and techniques to his own experiences as a diver. Bob taught Tony all he could on the Navy way to work and conduct himself. Tony’s knowledge of diving was gained by hard hands on experience. His understanding and respect for onsite diving safety, diving equipment and of the industry are second to none. Tony has earned his way by working as a helper, as a tender and as a working diver and has earned the respect and admiration of his father and our Clients throughout the Rail, Utility, Dredging and Refining Industry. After high school, Tony took the journey to college, even though he would have liked to follow his fathers and grandfathers "military" footsteps. He takes great pride in the knowledge gained while attending Bowling Green State University. He accomplished a Bachelor’s degree in education with a focus in science, math and history while still maintaining a career in commercial diving, working with his father.  Tony has brought the company many new ideas and has helped GLUS stay current with technological and equipment updates and changes. Tony maintains and updates Great Lakes Underwater Services “Operations and Procedures Manual” to keep their company operating above all known standards. Tony is practiced with all of the standards put in place for commercial diving and maintains his father’s Zero injury loss run record. Anything that can make the job or the equipment safer has been tested and implemented by Tony. He has earned industry wide recognition for his onsite safety practices and procedures. Tony has been a professional commercial diver since 1997.
