He is a past chair of the SFMOMA Architecture + Design Forum, and currently serves on the Headlands Center for the Arts Audience Engagement Committee.

An architect and researcher, Sarah Hirschman's broad expertise covers the resolution of complex technical designs and lecturing on the role of patterning and illusion in architecture, the subject of her research as LeFevre Emerging Practitioner Fellow at The Ohio State University. At Envelope she applies her talents to advance a range of work, including North’s technology-rich showroom system, compact mixed-use development in San Francisco, and the upcoming season at 2214, the firm's curatorial initiative.

Architect Lex Phelan studied and practiced abroad before joining Envelope. Here she has focused on projects involving sensitive cultural contexts and natural habitats, such as Radhaus, a restaurant within the historic Fort Mason Center, and a vision plan for the Headlands Center for the Arts. Her global perspective informs her interest in a sensory approach to architecture, recognizing the potential of the built environment to enhance physiological and emotional well-being among occupants.

The child of a metal sculptor, Ben took an early interest in the techniques of artistic form and material expression, but his path to architecture took a few turns. After completing an interdisciplinary degree in Environmental Studies from Oberlin College, Ben returned to his native Philadelphia and built skills in construction, initially through a year of service with Habitat for Humanity. Equally concerned with the social and technical aspects of architecture, he earned a Master of Architecture from California College of the Arts after moving to San Francisco.

Cassiopea is a designer focused on the way the built environment can play a role in social justice and reform, inspired by the seemingly invisible spaces that can bring people together. She earned her Bachelors of Architecture at California College of the Arts, focusing her education on urban and community design while working in conjunction with various nonprofit agencies, both at home and abroad. She continues to work within her local community, volunteering with organizations fighting to end homelessness and food scarcity. At Envelope, she has deepened her investment into community placemaking with the West Oakland Gateway project.

Obie builds Envelope’s public space and community engagement programs through thoughtful, connective experiences that tie people to place. Before Envelope, Obie produced events both nationally recognized and barely acknowledged as a Concert Producer at UC Berkeley. With a keen eye for logistics and a deep appreciation of shared spreadsheets, Obie designs and produces engagements, installations, and events that respond to the particular social and physical environments they take place within. His work on the NOW Hunters Point and PROXY projects stretches from community strategy to program design to site stewardship and everything in between - all of it of equal importance for creating and maintaining meaningful public space.

Tali grew up on an artists’ commune in rural Sonoma County, but escaped to attend UC Berkeley, earning a degree in economics followed by a Masters in Education from Mills College. There she became a passionate teacher and teacher educator. She went on to run the business end of a metal fabrication shop where she learned about design and construction. She joined Envelope in 2015, where she helps to manage the firm’s complex finances.
