Joseph got his start in the family business in 1998, learning the work firsthand out in the field. Over the years, he worked with architects and owners on design, pricing, and scheduling, building an understanding of what it takes to get a project from plans to construction. He later became an owner of AJM, carrying on the company Joe MacKinnon started. His approach comes from knowing the work and understanding how decisions on paper play out on the jobsite.
Jay graduated from Texas A&M in 2002 and went to work developing estimating procedures around the needs of each multifamily project. His experience includes pricing jobs, coordinating project needs, and keeping track of work across several projects at a time. He later became an owner of AJM, helping carry the family business forward. Jay knows that a good estimate takes more than running numbers. It takes understanding the job and what it will take to build it.
