This issue of Az Business features the Most Admired Companies in Arizona. To become one of Arizona’s Most Admired Companies, a business needs to excel in leadership, social responsibility, workplace culture, customer opinion, and innovation. And as the Most Admired Companies (MAC) program celebrates its 10th anniversary this year, only five companies have earned MAC status all 10 years, showing the sustained excellence and discipline it takes to be a winner on the marathon course — and in business. Those companies are American Express, CBRE, Sonora Quest Laboratories, Sundt, and UnitedHealthcare. Leaders from those five amazing companies are featured on the cover of this issue of Az Business magazine.
