Mark Zweig started this company over 30 years ago in Natick, MA. It has gone through a series of transitions in that time and seen plenty of ups and downs. Chad and Jamie Claire started a new generation of leadership here and I very much look forward to working alongside them to continue building the best management consulting and research firm in this industry.” Swearingen also commented on the parallelity of his own path to ownership with the services he offers his clients, “This brand, the products and the services that we deliver are all things I am passionate about. Being an owner here means a lot to me because my day job is to make this (ownership) opportunity a reality for architects and engineers [clients] across the US.” 

    Coldiron emphasized, “Being provided this opportunity to help lead Zweig Group into the future is one of the greatest recognitions anyone in our industry can have. The amount of pride this moment gives me is immeasurable. I’m looking forward to meeting the challenges with both clients and employees with the common goal of Elevating the Industry far into the future.” 

    Echoing the other two new owners’ sentiments, Keil added, “Partnership represents the next evolution of my ability to elevate our people. It furthers my personal drive for Zweig Group staff, the industry, and the larger communities we are involved in to be happy, fulfilled, and have the ability to realize their individual aspirations. This provides a larger platform to drive our purpose, performance, and to leave a lasting legacy.
