Phoenix Design One Promotes Sophia Humphrey to Principal

Joins executive leadership team, responsible for vision and growth of Scottsdale-based firm


Award-winning interior architecture firm Phoenix Design One Inc. (PDO) has promoted long-time team member Sophia Humphrey to the position of Principal. In her new role, Humphrey will continue to manage the PDO studio and directly oversee more than 40 buildings, of which PDO is the architect of record. She also joins the PDO executive leadership team, responsible for the vision and growth of the Scottsdale-based firm.

“Sophia is a tremendous mentor and is committed to continuously building PDO’s culture with an emphasis on fun, creativity and client care,” said PDO Principal Jennie Mayer. “She has exceptional talent and vision, both of which we know will help guide PDO into the future and build its next generation of leaders.”


Humphrey joined PDO in 2007, holding positions as Senior Project Manager and Associate. As Principal, Humphrey will continue to serve as a strong mentor in the PDO studio and support the continued education and creativity of her team. She will also continue to direct and expand the marketing presence for PDO within the industry.


PDO operates primarily in metro Phoenix, focused on office interiors but with a diverse portfolio that also includes medical, retail, education, financial and light industrial spaces. The firm has completed market-leading projects for companies such as Red Bull, Source, OH Partners and The Herb Box, as well as significant design and build-out activity within the high-demand, Class A speculative office sector.


Humphrey holds a bachelor’s degree in Interior Design from the Art Institute of Phoenix and a National Council for Interior Design Qualification (NCIDQ), the industry’s recognized indicator of excellence in interior design principles and commitment to the profession.
