🎉 Celebrating 43 Years of McNamara Custom Services, Inc. 🎉

Today marks a milestone that is incredibly meaningful to me and to our team. My parents, Glenn & Petra McNamara, started McNamara Custom Services in 1982 when I was just five years old — literally at our kitchen table with a dream, a work area, and a determination to build something that served others with excellence and integrity.

Over the decades, that dream has grown into what is now a second-generation Mechanical Contracting company, proudly serving communities throughout Central Texas. From those early days to where we stand today, one thing has never changed: our commitment to advancing value, protecting safety, respecting time and resources, and treating others the way we want to be treated.

Today, we employ an incredibly talented team of men and women who bring their best every day — in HVAC, Mechanical, Plumbing, Welding, and Industrial Construction services. We’ve had the privilege of partnering on projects with organizations across Texas, and we do not take that trust lightly.

As a second-generation leader, I believe my role is not just to build a company, but to build people — to mentor, to steward opportunity, and to create meaningful work that blesses families and strengthens communities. The legacy my parents began continues because of the dedication of our team and the loyalty of our customers and partners.

To everyone who has been part of this journey — thank you.

Here’s to the next chapter, filled with growth, excellence, and impact.

43 years and just getting started. 💙
