About Danboise Mechanical Inc.
Established in 1925, Danboise Mechanical Inc. (DMI) has evolved from a humble plumbing and hardware store into one of the Midwest’s premier commercial mechanical contractors. With nearly a century of experience, we are proud to continue the legacy of founder Alex Joseph Danboise, who built his business on a simple yet powerful principle: deliver top-quality service with integrity, every time.
Four Generations of Leadership
Today, Danboise Mechanical is proudly woman-owned and operated by Alex’s granddaughter Carol Danboise Gatewood and great-granddaughter Amy Gatewood Gendjar. Certified by the Women’s Business Enterprise National Council (WBENC) and the Supplier Clearinghouse, our leadership continues to drive innovation, growth, and customer satisfaction across all our service areas.
