Natthakanya Intharasena

Natthakanya (Namtan or Tan) was born and raised in Thailand. She received her Bachelor of Architecture from King Mongkut's Institute of Technology, Ladkrabang, working as a licensed architect in Thailand after her graduation. Through her travels and living abroad, Namtan has built an interest in the relationship between people’s activities, local culture and the built environment. She earned her Master of Advanced Architectural Design: Urban Works degree at California College of the Arts, with the goal of expanding her understanding in urban design. Outside of work, she likes to explore the Bay Area, sketch San Francisco’s housing, and figure out how to cook Thai food like her grandma and her mom.


Nathan John
Associate Partner

Nathan is a designer, writer and visual artist based in Oakland, California. Nathan’s work leverages the ethos and techniques of the hacker/maker movement and the material palette of the architectural avant-garde in testing the potential of small, temporary interventions to reorient our perceptions of urban environments. Nathan continues to build on this body of work as well as draw on his experience in community outreach through his leadership of envelopeA+D’s PG&E Hunters Point project. Nathan holds a Master of Architecture degree from University of California, Berkeley, where he received the Eisner Prize in Architecture, the department’s highest honor. He has also been the recipient of several fellowships supporting his research on public space, including the John K. Branner Traveling Fellowship, the UC Berkeley Arts Research Center Fellowship, and the Thomas J. Watson Fellowship. A child of the suburbs, he fell in love with cities while working as a bicycle messenger in Dublin, Ireland, and has been fascinated with them ever since.


Ben Leavitt

As the child of a metal sculptor, Ben took an early interest in the techniques of artistic form and material expression. Later during his undergraduate studies at Oberlin College, he took a generalist approach, completing an interdisciplinary degree in Environmental Studies along with minors in Politics and Studio Art. Upon graduation, Ben returned to his native Philadelphia and built skills in construction, initially through a year of service with Habitat for Humanity and subsequently through independent contract work in construction and carpentry. Soon after making a move to San Francisco, Ben decided architectural design would be a perfect confluence of these skills and interests. Equally concerned with the social and technical aspects of architecture, Ben achieved a Master of Architecture from California College of the Arts. When he’s not working in the studio, Ben enjoys exploring the urban and bucolic parts of the Bay Area by bicycle, improvising fresh cooked meals, and delving into his diverse record collection.


Cassie McDonald

Cassiopea gained 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. While there she was the recipient of several awards, including the Jury Honorable Mention and AIA Emerging Leader Scholarship. Since, she has continued to be inspired by the interaction of the built environment in social justice and reform. When not traveling the globe or backpacking some remote location, she can be found constantly creating, be it jewelry, furniture or a healthy dinner.


Lex Phelan
Project Designer

Lexie was born and raised in southwestern Pennsylvania. Through her explorations while studying at Virginia Tech in Blacksburg, VA, her time living in Shanghai, China and her experience working as a licensed architect in Germany, Lexie came to recognize the profound but often dismissed effects of our surrounding built environment on us and developed a strong interest in a sensory approach to the design of spaces and their materiality. When not designing, Lexie can be found riding her bike or skating around the Bay, playing roller derby or petting a dog in the corner.


Tali Reicher
Finance Manager

Tali grew up on an artists’ commune in rural Sonoma County where the free-spirit Kool Aid flowed. She escaped, spirit intact, to attend UC Berkeley with a major in Economics (surprising her parents for sure). Putting that degree to good use, Tali decided to pursue a Masters in Education and become a passionate teacher and teacher educator at Mills College in Oakland. After a stint as a stay-at-home parent (to three gorgeous children), she ran the business end of a metal fabrication shop where she learned a few things about design and a lot of things about the construction business. Tali joined envelopeA+D in the Spring of 2015 where she spends her days building and analyzing beautiful spreadsheets and telling people to stop spending money.


Clarke Selman

For the last decade, Clarke has been designing, fabricating and producing art installations around the globe. Educated at St. John's College, UC Berkeley and Harvard, Clarke took to handicraft shortly after completing school. Contemporaneously with his work in the art world, Clarke was introduced to envelopeA+D through his work crafting bespoke woodworking for their clients as part of his high-end luxury cabinet and furniture making practice in Oakland. Drawing upon his experience within the trades, Clarke joined the firm as expeditor in 2010 to liaise between contractors, clients, designers, architects, city inspectors and planners. After taking some time off to do a tour through corporate America, Clarke returned to envelopeA+D to streamline and facilitate special projects. If he isn't busy expediting, he can probably be found hiking across some rugged wilderness or canoeing around the bay.


Laura van den Bosch
Project Manager

Laura was raised in a quiet town on the shores of Lake Michigan. As a designer, she believes that sensitivity to the landscape and an enhanced relationship to the surrounding environment are fundamental to intelligent design. She strives to discover a sense of place through natural light rhythms, wind movement, and carefully composed views, and she savors the moments when structures are able to harmonize through materials and textures. Additionally, Laura appreciates the freedom and process of making with her hands, and she considers sketching and painting to be her primary tools for communication. Laura can be found hiking in the woods, snapping photographs on the coast, enjoying a vinyl record at home while perfecting a baking recipe, or riding her bike through the neighborhood. Laura is a Registered Architect in California. She holds a Bachelor of Science in Architecture and History of Art from the University of Michigan in Ann Arbor.


Veronica Volok
Studio Manager

Veronica grew up in the foggy, coastal city of Pacifica, known for its Taco Bell on the beach and annual dog surfing competition. She was pursuing a degree in psychology and got her AS in Social and Behavioral Sciences at CCSF. After learning about the world of advertising and marketing, she decided to change her major and transferred to SJSU to study advertising while minoring in Creative Arts. She worked as a Marketing Coordinator at Chrome Industries and Social Media Coordinator at ShenDesignWorks. As an avid cyclist and bike racer, she decided to take a break from her social media gigs and worked as a bike messenger in SF. When she's not racing or riding bikes, you'll find her at the office with her deaf mini Aussie, Bernie.
