Jim Rumford, Founder & President of Rumford Industrial Group
Founder & President
Jim Rumford

A Foundation in Industry. Jim's journey began in 1964 with the Eutectic Welding Corporation, while he studied Marketing at Wright State University. His technical expertise later led him to teach basic metallurgy and tool & die welding at Progress Tech Apprentice School in Dayton, Ohio.

The Birth of Rumford Industrial Group. In 1980, Jim founded Rumford Industrial Group from a garage, with a laundry room serving as the first office. That same year, he became the Great Lakes region distributor for Belzona polymeric repair compounds and industrial protective coatings.

Growth and Legacy. With support from Belzona founder JS Svendsen, Jim expanded the business across Ohio, Indiana, Southern Illinois, Kentucky, and Michigan. In 2013, he established a state-of-the-art facility in Miamisburg, Ohio, used for the education and training of technical consultants, contractors, and industry leaders.

Beyond the Industrial World. Jim is also the author of Tobacco, Trusts, and Trump: How America's Forgotten War Created Big Government, drawing from one of the largest private collections of primary documents on the historical "Tobacco Wars" and their lasting impact on American government and the economy.

A Century of Service. Celebrating 62 years in industrial sales in 2026, Jim continues to lead with the same energy that sparked the company's founding. His commitment to excellence and his "100-year plan" ensure that his impact on the industry will continue for decades to come.

Stephanie Rumford, Vice President at Rumford Industrial Group
Vice President
Stephanie Rumford
Stephanie started working for her father in 1980 at just 16 years old — a high school job that turned into a nearly 47-year career with Rumford Industrial Group. Along the way, she's worn nearly every hat in the business, from sales and marketing to human resources, shipping, and strategic planning, giving her a full view of how the company works from every angle. Through Rumford's work with Belzona, Stephanie has partnered with customers across virtually every industry, helping them solve difficult maintenance, repair, and corrosion challenges. What she's learned over the decades is that the real value isn't the products — it's the problems solved and the relationships built along the way. Today, Stephanie focuses on shaping Rumford's future: developing the team, strengthening customer relationships, and making sure the next generation can build on what her father started. Outside of work, she enjoys riding motorcycles, spending time with family, and life on the mini farm she shares with her husband.

He graduated from Kentucky Wesleyan College in 1983 with a BS in Chemistry, then joined and later managed Calchem Corp., a company manufacturing epoxy and acrylic coating systems for the packaging industry.

Mark joined Belzona and Rumford Industrial Group in 1995. While successful in sales, he thrives in applications. In 1999 he started IPR, Inc. for turn-key applications and continues to this day, focusing on chillers, cooling towers, tanks, and pits along with a broad range of other Belzona repairs. Mark has mixed and applied nearly every Belzona product and especially relishes the most innovative applications. Mark has three grown children living in Knoxville, Nashville, and Atlanta. He and his wife Paige recently celebrated 42 years of marriage. They are proud grandparents of a 2-year-old, with identical twin boys expected this fall.
