About the Top Pipe Rehabilitation Company in Phoenix, AZ

Our commitment to quality is second-to-none at Irontree Construction. As a well-respected and highly recommended in Phoenix, AZ, with 200-plus years of collective experience, we take pride in our portfolio of commercial plumbing and piping services.

A Look at Our History

In 1978, Gary Williams a manager with Fluor Corp, resigned his position and made the move from Southern California to Gilbert, Arizona with a plan to form a general contracting and development firm. His vision was to develop and build commercial projects and shopping centers. Due to the inflationary economy at that time, Gary was unable to obtain financing to complete his first project – in central Mesa. At the same time, Gary’s wife Helen a Mesa School teacher, met the wife of a local contractor. His company had just had a plumbing subcontractor default on a project and Gary was asked to complete the work. The successful completion of this project led to more work from this general contractor and from others.

Seeing the opportunity, Gary made the decision to continue Irontree Construction and Development, Inc. as a Plumbing Subcontractor. By hiring his first employee, Jerry Wood (recently retired) in October 1979, it cemented the path. By early 1981, Irontree had eight employees and was close to $1M in annual revenues, all while still working out of the Williams home office. In late 1981 Irontree’s first office was opened with the addition of Marj Weber as Office Manager (Marj continues advising as CFO today).

During all of those years, Gary and Helen included their children, Greg and Lori as integral participants in the business. Greg worked with Gary in the field from the beginning and eventually moved up the ranks to project foreman then project manager, VP of Operations, and finally President. Today Greg is 100% Owner of Irontree carrying on the legacy his father left. Lori began working for Irontree as an office assistant at 17 and was Accounting Manager before retiring. Although Gary suffered a stroke in 2011 and passed away in November 2013, the company he founded continues to live on in his children, grandchildren, and hopefully great-grandchildren.
