Dean DuPlantier AIA


Over his thirty years as a practicing architect, Dean Duplantier has amassed an impressive record of success. Yet for Dean, success isn’t about having his name attached to high-profile buildings or chasing design awards. It’s about executing quality projects and forging client relationships that become lasting friendships. In the end, he believes, successful architects design for their clients, not for themselves, and this focus on the practice of architecture continues to inspire his work and fuel his career.

Dean earned his architecture degree from the University of Louisiana at Lafayette in 1979. In 1982 he formed Broadmoor Design Group as an in-house firm providing design-build services to Broadmoor LLC, a Boh Brothers family company. In 2005, the firm evolved into an independent professional architectural corporation, retaining the Broadmoor Design Group name, its professional staff and Dean’s leadership. During its history, Broadmoor Design Group has completed a diverse array of projects including more than $500 million of military- and Department of Defense-related work. The firm’s achievements in multi-family and military housing design have been widely recognized, and in 2010 Broadmoor Design Group’s work on the new Holy Cross School in New Orleans was selected by Engineering News-Record Magazine as the best K-12 education project of the year.

Over the years, the firm has demonstrated the unique ability to lead reconstruction efforts after disasters. From hurricanes to industrial accidents, Broadmoor Design Group has been on the scene to help communities and companies recover quickly and come back better than before. Further, Dean’s diverse professional experience means he’s often sought after to provide forensic analysis and expert consulting services for complex design- and construction-related claims and litigation.

One of Dean’s most important accomplishments is his track record convening and leading the cohesive team of devoted professionals at Broadmoor Design Group, a team that together represents more than 150 years of architectural experience under one roof. This is the unique collaborative advantage and team chemistry the firm brings to every project.
