From our president

Building a healthy place in our world

Donna LaJeunesse

At Custom Contracting, we believe that our success stands firmly on the commitment of each of our team members to live up to our formally stated mission in everything we do for our clients, industry collaborators, and society

at large.

That mission—to build a healthy place in our world—in all its multilayered meaning embodies our legacy, our culture, and our very reason for being. It’s why we do what we do.

 

From the company’s earliest days, we’ve understood how the work we do impacts the success of our clients and the quality of life for those who work and live within the environments we create. As the construction industry continues to evolve, Custom Contracting stands poised to lead across the dimensions that matter most to our clients and our company.

 

The quality of our work, our clients’ satisfaction, and the longevity of relationships with them offer proof of our dedication to the industry’s highest ethical standards and the application of state-of-the-art materials, methods, and technologies.

 

Just as critical is our commitment to equity within and outside our organization. We bring that to life by recognizing that every individual comes with a unique set of talents, capabilities, and circumstances and by enabling each with the tools and resources required to succeed and thrive.

 

Examples of that are the certifications of Custom Contracting as a Women’s Business Enterprise (WBE) by the Women’s Business Enterprise National Council, State of Illinois BEP, and the City of Chicago. These certifications broaden our business prospects with others who value equality and diversity, underscoring our company’s unwavering commitment to equity.

 

I have witnessed personally how well this works within our company and the impact it has for those who engage and interact with us outside our walls. It is essential to leadership and a prerequisite for fulfilling our mission.

 

In it together. Plans may change, our commitment doesn’t.

Our history

Bringing a vision to life

Custom Contracting came to life as a carpentry-focused business in 1987 in Lake Zurich, Illinois, The vision for the company arose from Leon and Carol LaJeunesse’s desire to build the best possible life for their young family, which had expanded to four—soon to be five—at the time of the company’s founding.

Through referrals from industry representatives and satisfied customers, Custom Contracting quickly gained a solid reputation for high-quality work and the conscientiousness of its management. An early opportunity—working with design-build teams to construct cleanrooms for a global manufacturer—led to engagements to reduce energy costs on Illinois School District projects and major upgrades in several Chicagoland school districts.

That mix of cutting-edge expertise and deep experience proved ideal qualifications for the highly specialized work that occupied healthcare construction projects require, which led to a major contract with one of Chicagoland’s largest healthcare systems. Today, Custom Contracting has master agreements with several of the area’s premier healthcare providers and continues to expand its business into other industries that require its brand of expertise, quality, and reliability.

In 2023, Custom Contracting again demonstrated its forward-thinking corporate leadership when it achieved formal certifications as a Women’s Business Enterprise (WBE) by the Women’s Business Enterprise National Council, State of Illinois

BEP, and the City of Chicago, which confirm that the company is at least 51

percent owned, operated, and controlled by women. A rarity in the construction industry, WBE certification sets Custom Contracting apart and enhances its value to current and future clients.
