Celebrating 42 Years of MSD, Inc.: Built on Legacy, Driven by the Future

/ Uncategorized / By

This year marks an incredible milestone for MSD, Inc., 42 years of service, growth, and innovation.

What started in 1984 as a small, family-owned business in Ohio has grown into a trusted, full-service facility solutions provider. From day one, MSD was built on a simple but powerful foundation: quality work, strong relationships, and unwavering integrity.

From Humble Beginnings to Industry Leader

Founded by John and Beverly Stewart, MSD began with a commitment to doing things the right way. That commitment still defines us today. Over the decades, we have expanded our capabilities and evolved into a company that delivers comprehensive facility solutions, including HVAC, plumbing, electrical, building automation, and design-build services.

Today, MSD is known as a trusted partner for complete facility solutions, supporting everything from routine maintenance to complex system design and installation.

A Legacy That Lives Through Our People

While our services have grown, one thing has stayed the same. Our people are at the heart of everything we do.

For more than four decades, our team has carried forward the values that built this company. They work hard, solve problems, and show up for our clients every single day. That culture of dedication and pride has allowed MSD to grow from a small operation into a company with a strong regional presence.

Celebrating the Journey

To celebrate 42 years, we have been looking back at where it all began.

Across our social channels, we have been sharing throwback photos that capture early projects, original team members, and key moments in our history. These snapshots tell the story of how far we have come and the people who made it possible.

Looking Ahead

While we are proud of our history, we are even more excited about the future.

With continued growth, expanded services, and a focus on innovation, MSD is committed to helping our clients operate smarter, more efficient facilities while staying true to the values that got us here.

42 years is more than a milestone. It is a reflection of the trust of our clients, the dedication of our team, and the strength of our foundation.

Here’s to where we started and where we are going next.

WPAFB Sensors Lab

Wright-Patt Air Force Base sought contractors to renovate and add onto the Sensors Lab. The HVAC portion of the project was over $13 million.

  • MSD served as the Design Assist Contractor in conjunction with Heapy Engineering for this project. In collaborating with General Contractor, Butt Construction, MSD provided Design Assist solutions for the following:
    • A large, anechoic chamber
    • An outdoor range
    • Multiple, Class-100 clean rooms
    • A three-story office building addition with DCID 6-9 requirements on many of the rooms

WPAFB Chilled Water System

The chilled water system at a high-security building on the Air Force Base was undersized and unable to keep up with demand. The facility could not operate without chilled water due to the amount of information servers in the building, and the general nature of the building itself. The entire upgrade project would need to be completed with minimal shut down time at the building. HVAC portion of this project was over $3 million.

  • MSD worked in collaboration with Diaz Construction to complete the system upgrades on time and on budget with minimal shutdowns or disruption to the facility operations.

LJB, Inc.

LJB, Inc. was renovating their Miamisburg, OH office and wanted to incorporate energy-saving upgrades.

  • MSD provided Design Build services in tandem with Greensleeves Energy Solutions, a specialist in geothermal systems.
  • MSD and Greensleeves installed a new geothermal HVAC system with open and closed loops. In addition, MSD design and installed the plumbing portion of the renovation.
