Sean trained as an architect at UC Berkeley and MIT, and worked in Tokyo and San Francisco. He founded Otto in 2019 to bring design, permitting, and construction under one roof, and now leads strategy and client relationships across Otto's rebuild, custom, and ADU work.

Alex leads design and architecture at Otto, working directly with homeowners to translate vision into permit-ready drawings. He oversees the architectural team and the design review process on every project, ensuring the vision developed with clients is the home that actually gets built.

Chris leads the construction phase at Otto. With 7+ years experience managing high profile multi-family projects across LA, Chris has a wealth of knowledge to draw on as he ensures design integrity and construction quality.
