Our Legacy

Perkins Eastman claims a proud legacy, with roots reaching back more than a century when Co-Founder and Chairman Brad Perkins’ grandfather, Dwight Heald Perkins, started an architecture firm in 1897. Dwight later received commissions for the design of two universities in China. Brad’s father, Lawrence Bradford Perkins, would go on to form the global firm Perkins+Will. The third generation would look different, however, when Brad partnered with Mary-Jean Eastman to establish a new firm in 1981. Brad brought experience as a managing partner, and Mary-Jean possessed key skills in managing large projects with programmatically complex buildings. Mary-Jean’s ability to connect with public-sector and healthcare clients, many of whom were women, plus Brad’s acumen for building an international business, added up to a winning partnership that has enabled Perkins Eastman to grow into one of the largest and most respected design firms in the world. Mary-Jean and Brad’s singular focus across all practice areas was—and remains—to have a direct, positive impact on people’s lives and the planet. By offering architecture, interior design, planning, and strategic-consulting services, the firm has grown to more than 1,100 employees and 24 studios around the world. And because so many of our projects are now executed on grand scales, each of them requires many of our core areas of expertise to converge, producing an outcome that’s thoroughly Human by Design. Our design recognition, expertise, and geographic diversity have thus enabled us to work on fascinating assignments in more than 60 countries across five continents earning more than 800 awards along the way and still counting.  All the while, like their own partnership that seemed so novel 40 years ago, Mary-Jean and Brad have fostered a firm culture with a premium on diversity that starts at the top.

Brad Perkins + Mary-Jean Eastman

Brad Perkins and Mary-Jean Eastman originally met at Llewelyn-Davies International in the 1970s. Brad moved to Perkins + Will in 1977, and Mary-Jean followed a year later. While there, Brad served as the Managing Partner of the Eastern offices while Mary-Jean ran the major design studios. They partnered with Eli Attia to form Attia & Perkins in 1981, which is where the Perkins Eastman story begins.

    As part of the merger with Basler Mosa Design Group, this was our first studio established in the Middle-East/North Africa (MENA) region as Perkins Eastman embarked on the large Park Hyatt resort on Saadiyat Island in Abu Dhabi.  The firm has since been recognized among the Top Ten in the Middle East. It provides crucial local management support for MENA-region projects across many practice areas, including Master Planning, Mixed Use, Residential, and Hospitality. That support means that even if a project is being designed in a U.S. studio, the firm can hold client meetings in the local time zone on that project, such as Kuwait University in Kuwait City, and in Saudi Arabia, Aramco’s New Community in South Dhahran and Dallah Hospital in Riyadh.
