“Amazing things happen when you sit in a room full of people who are all employed in the same career field. Through our involvement with RMMI, we are exposed to new opportunities via networking and professional development with like-minded industry leaders who are immersed and vested in this business. The organization helps its members forge important relationships, and turns competitors into teammates. RMMI’s continuing education and apprenticeship programs further promote a commitment to developing masters in our trade. The benefits of membership are countless.” - Josh Cronholm, Ammex Masonry

"As an engineer, I look for masons who are RMMI Certified. I can have confidence that these masons have been through a rigorous training and education program. RMMI Certified masons represent the cream of the crop of the masonry industry, including companies that have done quality work in and around Colorado for many decades. I specify and recommend RMMI Certified Masons because I tend to have fewer problems on site and get higher-quality results than leaving mason selection to a low-bid process." - Donald Harvey, P.E., Atkinson-Noland and Associates
