Master Builders of Iowa strives to be the essential resource for Iowa’s construction industry and a valuable component of that effort are the companies who support MBI’s programs and events. Through the exclusive Essential Partners recognition program, MBI strives to recognize our industry supporters, while adding value to those companies’ sponsorship dollars who take leadership roles in sponsoring MBI events and educational opportunities. Companies that are considered MBI’s Essential Partners have contributed over $3,000 in sponsorships to the Master Builders of Iowa in the past year. These companies are an important part of MBI’s success and we couldn’t do it without them!

MBI’s Essential Partners are profiled on the MBI website, with direct access to their listings from the homepage. They also receive a full-page company profile in an edition of InsideMBI, the association’s quarterly news magazine. These profiles are very exclusive offerings since MBI does not offer advertising on the website, nor in the magazine.
