�Mike has been instrumental in establishing SGPA�s presence in Northern California,� says Dave Reinker, president. �He�s provided leadership in many areas including establishing the branding of our retail, mixed-use, senior living and wellness studios. While we�ll miss him, he�s left a strong framework for all of us to build on.�

As part of implementing an overall firm perpetuation plan, Collier�s departure brings the opportunity for new promotions and role transitions through a process that began in early 2010.

San Francisco Principal and Operations Director Stuart Lyle has been promoted to director of the San Francisco office and will also take over the role of director of business development for Northern California. Lyle�s long history with SGPA started as a student intern in 1988. He later re-joined the staff in early 1993, becoming a principal in 2004. Lyle is a graduate of Montana State University, a member of the Montana State University School of Architecture Alumni Advisory Council and chairman of the Advocacy Committee. He is also a CSI-Certified Construction Contract Administrator and an active member of the International Council of Shopping Centers (ICSC).
