This year marks a meaningful milestone for MacLellan Integrated Services as we celebrate 30 years of supporting our customers, developing our people, and building a company rooted in trust and accountability. Founded in 1994, MacLellan began with a focused mission to deliver critical industrial services directly inside our customers’ facilities, helping them operate more safely, efficiently, and competitively. What began with a small number of dedicated teammates has grown into a trusted partner supporting manufacturing operations across North America.

Throughout our history, our growth has been guided by long-term relationships and a commitment to showing up every day with ownership and discipline. From our early work in automotive paint shop support to today’s broad portfolio of facility services, production support, maintenance, HVAC, and wastewater management, MacLellan has evolved alongside our customers by listening closely and delivering what they need most when it matters most.

Our success over the past three decades is driven by our people. From frontline teams embedded in customer operations to the corporate staff supporting them from our headquarters in Lexington, Kentucky, MacLellan has remained focused on developing talent from within and fostering a culture where accountability, safety, and respect are nonnegotiable. Leadership continuity, built on experience and trust, has allowed us to grow responsibly while staying true to who we are.

As we look ahead, we are energized by the opportunities before us and confident in the foundation we have built. The manufacturing landscape continues to evolve, and MacLellan is prepared to meet the future with the same focus and integrity that shaped our past—with great people, disciplined systems, and a shared commitment to excellence. We are grateful to our employees, customers, and partners for making the last 30 years possible, and we are excited for what we will build together next.
