Bob
McCollum

The Long Game, Played Quietly

There's a specific kind of CEO who doesn't appear in Forbes lists or give keynotes at Davos. Bob McCollum is that CEO. For decades he ran R.S. Hughes Co., Inc. - an employee-owned industrial distributor in Sunnyvale, California - with the kind of steady, relationship-built authority that doesn't photograph well but compounds beautifully over time. R.S. Hughes went from a regional adhesives shop to a $527 million enterprise with over 45 warehouse locations spanning the United States, Mexico, and Costa Rica. McCollum was at the controls for most of that climb.

He started as a quarterback. Not metaphorically. Bob McCollum was literally throwing footballs for the University of Michigan in 1956 and 1957 - first on the freshman squad, then on varsity. He graduated in 1961 with a degree in Speech and Business. Both choices turned out to matter: the speech part explains how he ran meetings, and the business part explains everything else.

R.S. Hughes was founded in 1954 by Robert Saunders Hughes in Glendale, California. Hughes started with a simple conviction: industrial supplies should be stocked locally, close to the manufacturers and assemblers who need them. McCollum didn't found the company - he inherited its mission and scaled it. By the late 1980s, he was making acquisition calls, picking up Dayton Distributors and integrating it into the RS Hughes network in Tampa, Florida. That move required more than a wire transfer - it required someone willing to personally broker a culture fit between two very different regional teams. McCollum did it by being the kind of executive who actually shows up.

Long-time RS Hughes employee Larry Loomis, who spent 33 years with the company, remembers McCollum with the clarity of someone who hasn't forgotten a single detail: "Bob and I had a great lunch, and he took the time to get to know me, offering advice and showing genuine interest in my future." Loomis adds simply: "Bob was always personable with everyone in the office." For a CEO running a company across dozens of locations, that's not a given. For McCollum, it was non-negotiable.

The Company He Shaped

R.S. Hughes sells what manufacturers need to build, protect, and ship things: adhesives, sealants, tapes, abrasives, safety gear, metalworking supplies, cleanroom materials, aerospace-grade fasteners. The product catalog runs into the thousands of SKUs, serving aerospace, medical, manufacturing, transportation, and defense customers who cannot afford supply chain surprises. RS Hughes ranks in the Top 30 of Industrial Distributor's annual Big 50 list - a ranking that doesn't go to companies run on autopilot.

The key to that ranking is the employee-owned structure. RS Hughes is not publicly traded. There's no Wall Street pressure to cut the relationship-building, the multi-generational employment culture, or the field-level investment in people. McCollum understood this clearly: you can't build a multigenerational workforce if you treat the workforce as a line item. The Alker family logged 50 combined years at RS Hughes. Norman Thomas joined in 1974 and stayed until 1993. His son Scott joined at 17 and stayed until 2021. That kind of loyalty doesn't happen by accident - it's built, one lunch, one phone call, one Dayton Distributors integration at a time.

Michigan, Always

Bob McCollum never stopped being a Michigan man. He raised his family in Palo Alto, California - both sons went to Palo Alto High School, where they happened to cross paths with a certain future NFL head coach named Jim Harbaugh. But Palo Alto was never the alma mater that held his loyalty. Ann Arbor was.

In 2016, McCollum created the Robert McCollum Endowed Football Scholarship at the University of Michigan - a direct investment in the program he played for six decades earlier. Then in October 2022, he went further: a $2 million gift to endow the quarterbacks coaching position. The Robert McCollum Family Quarterbacks Coach is now a named, permanent institution within the Michigan Athletics structure. Kirk Campbell held the position first, followed by Chip Lindsey. McCollum funded the role that teaches the position he played.

That's not nostalgia. That's a specific kind of commitment - to the institution that shaped him, to the position that defined his playing days, and to a program that had given him something he still carried. He wasn't buying a name on a building. He was funding the exact job he once needed someone else to do well for him.

How Leadership Compounds

McCollum's tenure at R.S. Hughes coincided with the company's most dramatic growth. During the years when Pete Biocini - hired into the company in 1982 - served as President and then CEO, the company grew from $20 million in annual sales to over $430 million. McCollum as CEO provided the strategic context in which that growth could happen. Then in November 2020, Biocini passed away. Bill Matthews was elected CEO. McCollum transitioned to Chairman, completing a leadership succession that had been built over decades of internal promotion rather than outside hires.

By April 2025, Matthews retired after an 18-year run in executive leadership, and John Mathis - a 12-year company veteran who had served as Chief Revenue Officer - took the President role. The pattern is unmistakable: RS Hughes builds its leaders from within, promotes based on proven trust, and hands the company to people who already know where the bodies are buried and how the culture actually works. That's not an accident. It's what happens when the people at the top prioritize institutional integrity over short-term signals.

McCollum didn't build a company. He built an institution. One that keeps producing its own successors, keeps certifying operations in Costa Rica (AS9120B, February 2026), keeps opening manufacturing facilities in Houston, and keeps landing in the industrial distribution Top 30. The adhesives are just the product. The architecture is the thing.

The Profile in Full

Born in Struthers, Ohio. Played quarterback at Michigan. Graduated 1961. Moved to California. Joined R.S. Hughes. Acquired companies. Built a culture. Raised a family in Palo Alto. Gave Michigan $2 million. Stepped back when the time was right. Left an institution better than he found it.

That's the biography in compressed form. The actual work is harder to describe: it's in every lunch with an employee whose name most CEOs wouldn't remember, every acquisition integration where someone had to convince two sets of regional salespeople that their new colleagues weren't the enemy, every warehouse location that got opened because someone at the top believed the market was there before the market could prove it.

Bob McCollum played the long game at a company that rewards playing the long game. The result is a $527 million enterprise with a culture so stable it produces three-generation employee families. In an era of disruption theater and pivot announcements, that's the quieter achievement - and possibly the more durable one.

What He Built

R.S. Hughes at a Glance

R.S. Hughes distributes the materials that hold things together - literally. The product catalog includes thousands of SKUs across categories that sound mundane until you realize aerospace, medical, and defense manufacturers can't ship a single product without them.

RS Hughes serves aerospace, medical, manufacturing, transportation, defense, and government customers. The employee-owned structure means no public shareholders pressuring quarterly margins - an unusual luxury that allows the company to prioritize relationships and service over short-term optimization. That structure is foundational to the culture McCollum built and the succession he left behind.

In February 2026, RS Hughes Costa Rica received both ISO 9001:2015 and AS9120B certifications - the gold standard for quality management in aerospace supply chains. In May 2025, the company opened a state-of-the-art manufacturing facility in Houston. The company McCollum shaped keeps expanding, keeps certifying, keeps climbing.
