MRG began in 2006 as a family business in Nashville, TN. David purchased Mechanical Resource Group from Greg Smith, who started the company as a small hydronics representative with five employees. Sons Matt and Jon joined thereafter and by 2011, the company had doubled in size, serving across Middle Tennessee. 

With roots in pumps and hydronics, MRG has expanded its expertise to include over 15 categories, specializing in HVAC and controls. Over the past 15 years, MRG has established its position as the market leader in Nashville through its mission to serve one customer at a time. 

Today, MRG is distinguished by three characteristics:
