Landscape Architect Michael O’Brien has been promoted to Associate. With more than 30 years of professional experience, Michael brings finely honed design and management expertise and is valued for his mentorship of emerging landscape architects. His sensitivity to site context, ecological function and human experience informs all of his work. Michael’s recent projects include OHSU’s Doernbecher Children’s Hospital expansion and Errol Heights Park in Southeast Portland.  

Senior Visual Communications Designer Margaret Drew has been promoted to Associate. Margaret is recognized for her approach to planning and designing inclusive wayfinding systems that inform, guide and connect people across differences in language and ability. Her recent work includes leading signage standards for Multnomah County Library’s 15-branch system.  

Content Coordinator/Editor Stefanie Warmouth has been named Associate in recognition of her vital role in quality control and promoting Mayer/Reed’s story and culture.
