At M-D Building Products, our people are the driving force behind everything we do.

Recently, we brought the excitement to our team with a special employee appreciation event featuring Rumble the Bison and members of the Oklahoma City Thunder Girls! Employees enjoyed a complimentary BBQ lunch, snapped photos with our special guests, and celebrated together as we recognized several of our MVP employees for their outstanding hard work and dedication.

Moments like these are a reminder that success is built by great people, strong teamwork, and taking time to celebrate the accomplishments that move us forward.
Thank you to every member of the M-D team for everything you do. Here's to continuing to build, grow, and win - together! 💙🏀

The 2026 M-D Building Products Golf Scramble was a huge success!

We were proud to welcome 100 participants representing 27 vendor partners for a day filled with great competition, networking, and giving back to a cause making a meaningful impact in our communities.

This year, we were honored to support the Center for Employment Opportunities (CEO), an organization dedicated to helping individuals recently released from incarceration build brighter futures through employment opportunities, skills training, and ongoing career support. CEO’s mission to create pathways toward long-term social and economic mobility is making a lasting impact in communities across the country, including right here in Oklahoma City.

Thanks to the incredible generosity of everyone involved, we were proud to present a donation of $20,000 at the conclusion of the event.

Each year, this tournament gives us the opportunity to support a different cause and continue building stronger communities, something that’s at the heart of who we are at M-D Building Products.

A special thank you KickingBird Golf for being an outstanding host, and to every participant, sponsor, and donor who helped make this event unforgettable.
