In 1988, Loretta Rosenmayer’s husband was diagnosed with a chronic illness and forced to stop working. As a stay-at-home mom with four young boys, it was clear that she had to become the breadwinner in the family. With a minimum wage job out of the question, and no money or construction experience, she accepted donations of used equipment from a friend’s out-of-business landscaping company and started trenching work for farms in Crystal Lake, IL. With four employees and meetings conducted at a local diner, Trench-It was born.

Shortly after, Illinois experienced a housing boom and utility companies couldn’t keep up with installing new home services. With a $15,000 loan from a female friend, Loretta was able to afford insurance premiums and started bidding jobs for the local utility.

In 1993, Loretta had the foresight to become certified with WBENC (Women’s Business Enterprise National Council). That relationship gave her an early edge with utility companies who were looking to expand their minority diversity spend.

As the only female, she was met with opposition. However, all the utility companies were concerned with was delivery and Loretta delivered. Soon Trench-It moved into electric overhead and underground and then gas services. By 2009, she changed the name to INTREN; the “IN” standing for integrity.

During the late 2000 recession when the business slowdown forced cutbacks, Loretta started looking outside of Illinois and took small jobs that no one else wanted.  When the economy came back, INTREN’s footprint quadrupled and they were instantly in 10 markets across the country.

To Loretta, stewardship “caring for other’s priorities as if they were our own” is not just a way of doing business; it is a way of life. By weaving this into the very fabric of INTREN’s culture, Loretta and the company have succeeded in earning the respect and support of peers, customers and the communities INTREN serves. And that has always been Loretta’s purpose--to serve and to make a difference. You see it in her mentoring of dozens of MWBE companies and the hundreds of charitable organizations she supports and how she passionately takes care of her customers and employees.
In 2017, Loretta stepped up to Chairwoman of the Board, and hired utility industry-veteran Kelly Tomblin as CEO.  Together, their vision for the future is to acquire and mentor additional MWBE companies, while continuing to strategically expand into new regions and deepen INTREN’s breath of services.

Now with 13 regional offices, 2,000 employees from coast-to-coast, and additional services in transmission and vegetation management, their vision is becoming a reality.

Unique Woman-Controlled Board Welcomes Miller 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.

On Thursday, June 14, 2018, James Althoff from our Business Development department graduated from a nearly year-long leadership program in McHenry County: Leadership Greater McHenry County James Althoff stands with LGMC Plaque(LGMC). Unlike a more traditional skills based approach to leadership, James described LGMC as teaching its students to focus on understanding "what issues affect us, regionally, locally, and nationally".

Leadership can be viewed through a narrow lens as a tool to only be utilized in the workplace, but James learned how to utilize leadership skills to better serve the community. To that end, he studied Human Trafficking.

Human trafficking is an insidious problem in the Midwest, often times connected to drug routes flowing through Chicago. "Chicago, Rockford, McHenry are known as the trafficking triangle," James said. In addition to learning communication skills and other typical facets of leadership, James also learned to apply a leadership perspective to a broader angle. Part of why human trafficking continues to plague this region is that "we live in a bubble, so we don't see the periphery". People have to step up in their communities and assume leadership roles in order to combat issues pervading the local area.

Other teams in the program studied issues such as opioid addition or economic issues. James and the other graduates learned to "connect, educate, [and inspire engagement] in the community", andJames Althoff speaks at a podium doing so manifested itself through the variety of topics people dove into.

"It's really harder than it seems, it's trying to find out what your passion is and giving back to the community in some way," James said.

James is the 4th INTREN employee to complete the program, joining Sue Clarke, Mary Lucarelli, and Christina Mazhary as a fellow graduate of LGMC.
