At our September celebration of Group 4’s 50th anniversary, we reflected on our journey through five decades of collaboration with communities, clients, and colleagues to plan and design innovative public architecture. As we look to the next 50 years, we are excited to share the next evolution of firm leadership.
Group 4 is proud to announce the promotion of Carolyn Carlberg, Daniel LaRossa, and Teresa Rom to Associate Principal and Jill Eyres to Principal. Each of these individuals brings unique experience, a passion for public architecture, and a deep commitment to Group 4’s mission: creating spaces where communities can gather, imagine, and grow. Their creativity and dedication have shaped diverse aspects of the firm’s practice during their 15+ year tenures with Group 4, and their vision and leadership will continue to guide our future direction.
