Master Manufacturing Group will invest $3.9 million to relocate its headquarters and manufacturing operations from Rancho Cordova, California to Dayton, Tennessee. The company plans to create 72 jobs over the next three years.

MMG will renovate and upgrade an existing manufacturing facility located at 220 Masters Way. The building will also undergo extensive retrofitting in order to install holding tanks, electrical and hydraulic infrastructure, and create adequate ventilation for welding and painting operations.

“We are honored to be a valued community partner in Dayton and Rhea County. The state and local government and economic development leaders have an obvious passion for this community. The Rhea County High School technical program does great work in providing technical training to their students. Moreover, we have discovered they also prepare their students by challenging them to mature in life skills and work with a spirit of excellence. Although the current economic environment presents many unique and unforeseen challenges, we have high expectations for great results as we expand employment with the local workforce over the coming years,” expressed MMG President Eric Griesemer.

“TVA and City of Dayton Electric Department congratulate Master Manufacturing Group on its decision to locate and create new jobs in Dayton. Helping to support new job creation and investment is central to TVA’s mission of service and we are proud to partner with the Tennessee Department of Economic and Community Development and Rhea County Economic and Tourism Council to further that mission,” said John Bradley, TVA Senior Vice President of Economic Development.

Founded in 1956, Master Manufacturing Group, formerly known as Woodmack Products, Inc., provides custom tube and pipe manufacturing services, specializing in the gas appliance industry. The company offers aluminum, stainless steel and steel tubing components in various shapes, sizes and forms.

“What happens in rural Tennessee affects every Tennessean, and so we're excited by this investment from Master Manufacturing Group to bring more jobs and growth to Rhea County. I appreciate MMG for choosing to do business in our state, and I look forward to the many ways this new operation will spark economic activity in Southeast Tennessee,” Governor Bill Lee said.

“We are pleased to welcome another West Coast, California-based company to the Volunteer State. Tennessee offers companies around the world a favorable business climate and attractive competitive advantages. We thank Master Manufacturing Group for its $4 million investment and commitment to create over 70 new, family-wage jobs in Dayton. This project will have a sizable impact on Rhea County, one of Tennessee’s at-risk counties, in the years ahead,” noted Bob Rolfe, Commissioner of TNECD.

MMG utilizes multiple manufacturing processes including CNC machining, mandrel bending and forming. Processes such as robotic, semi-robotic, manual welding as well as high pressure and high purity welding will be performed in-house at the Dayton facility.
