INTREN Finalizes Transaction to Acquire Miller Construction Company


Unique Woman-Controlled Board Welcomes CEO Christina Ernst


INTREN, one of the nation’s largest certified Women Business Enterprise (WBE) specialty utility contractors, today announced they have closed the transaction to acquire Indiana-based Miller Construction Company, Inc., a third-generation full-service electrical contracting company, which is also a leading WBE.  INTREN’s focus now is a thoughtful integration of both companies.

“An acquisition evokes a myriad of emotions for employees and our focus now is on bringing our teams together in a way that minimizes any concerns,” said INTREN CEO Kelly Tomblin. Miller has an extraordinary team and we want to make sure they continue operations with as little interruption as possible. My intention is to assemble a creative integration team that will uncover and implement the best practices of both companies.” 

Miller Construction’s 175 employees join INTREN’s 1,700-strong team to provide more to complete service offering through a wider geographic reach. Company President Andy Carmean will continue to oversee Miller activities and will join INTREN as Regional Vice President serving the Indianapolis and St. Louis markets.  Christina Ernst, CEO of the Miller Construction Company, will join the woman-controlled INTREN Board of Directors, one of the few in America’s utility contractor space. 

“Today, Miller employees are officially a part of the INTREN family, said Tomblin. However, we will continue to honor the Miller legacy and the three generations that built this extraordinary company. Our companies share similar roots, along with the same culture and values that are centered upon a deep customer focus, an ongoing commitment to safety, and a true caring for our employees and the communities we serve.” 

INTREN Founder and Board Chair Loretta Rosenmayer stressed that INTREN’s acquisition furthers her vision of creating a national full-service company. “Our goal is not only to build the best women-owned business and woman-controlled board, but to be the best overall total-solutions provider for our customers. INTREN’s and Miller’s shared values of stewardship, integrity and customer focus will guide us, and firmly support our belief that companies do well in the marketplace by doing good,” Rosenmayer added. 

This acquisition is in response to requests from our customers and the marketplace. We are expanding our transmission capabilities and expertise, and adding other services such as equipment testing, vegetation management and innovative professional services while maintaining the same safety, quality, and customer focus that INTREN has provided for nearly thirty years. We are now well-positioned to grow further and be even better partners for our customers in the future,” added Tomblin.

“As a family-owned and operated WBE, Miller Construction Company is thrilled to join the INTREN family,” Christina Ernst said. “Not only does INTREN embody the principles and values of Miller Construction Company, but we provide complementary services that will help INTREN achieve continuous growth and become a total utility solutions provider. Together we are well-positioned for industry leadership that will provide creative solutions for our customers.  I look forward to serving on the Board and continuing to help advise the combined companies.”

INTREN’s acquisition of Miller Construction Company shows the industry that diverse companies can combine to create a different and innovative workplace offering.  INTREN’s latest growth to meet the infrastructure needs of the utility marketplace reflects their 30-year trajectory that was bolstered in 2017, when One Equity Partners became a minority investor, providing significant funding for future growth.
