Diane Thepkhounphithack
Senior Project Manager | Director
Diane Thepkhounphithack’s career has been built in the work itself—where leadership is measured by clarity, follow-through, and the ability to move complex projects forward. Her experience across design and project management roles at BROOKS + SCARPA Architects, Hawkins\Brown, and OFFICEUNTITLED has shaped a grounded, pragmatic approach to practice.
At OU, Diane has led projects including 1527 Lincoln, 2919 Wilshire, and 2800 28th Street, navigating adaptive reuse, mixed-use development, and technically demanding scopes with precision and care. A daughter of Lao refugees and a longtime Angeleno, she brings a deep commitment to Los Angeles and to the people who shape its built environment.
Diane initiated and leads OFFICEUNTITLED’s mentorship program, ensuring all staff, especially junior team members, have access to guidance and advocacy. She has also served in leadership roles with AIA Los Angeles and the Laotian American National Alliance. For Diane, leadership is rooted in support, listening, and shared responsibility—values she sees as inseparable from good design.
