Navin Pathangay, AIA Principal

While Navin was formally trained at the University of Florida and the University of Michigan, he knew he wanted to be an architect when he was just seven years old. Awestruck after walking through a new house in the Mauritius Island neighborhood where he grew up, Navin expressed his admiration for the work. The architect, a family friend who also owned the house, took Navin under his wing and the rest is history.

A world traveler, Navin is continually inspired by the colors, textures and materials of different cultures and localities. Throughout his career, Navin has worked on projects in Africa, Europe and the United States. Prior to starting his own company, Navin worked as a project designer for Kadhusin Associates in Ann Arbor, Michigan, and as a project architect/manager for DWL Architects and Planners in Phoenix, Arizona.

For six years, Navin taught design fundamentals at Arizona State University. He loves to share his knowledge and continues to inspire the next generation of architects by training recent graduates and judging student design competitions.

In his free time, Navin likes to experience the outdoors, travel and explore the world.
