KLB Construction, Inc. was founded in 1984 by Kelly Lynn Bosa — a 25-year-old mother of three. Thanks to her father, Kelly had grown up immersed in the construction industry, beginning her career as a traffic control flagger.
But Kelly had higher ambitions, and soon decided to risk it all by going into business for herself. With hard work and the support of her family, she grew her once-small business into a successful company with over 250 employees. Still family-owned and operated, KLB Construction runs on the principle that by working together as a community, even the biggest challenges can be overcome.
