The Portal House

33 Reed Blvd, Mill Valley, CA 94941, Mill Valley, CA

The Portal House is a coworking and wellness club in Mill Valley that blends a productive workspace with a full thermal recovery suite. Inspired by the ethos of Burning Man, it brings a community-first sensibility to the idea of a members club, pairing desks and gathering spaces with dedicated rooms for heat, cold, and light therapy. Members enjoy unlimited access to a communal sauna, a cold plunge, and a red light therapy room, making it easy to fold recovery into a normal work day. The model is built around membership rather than drop-in visits, so the crowd tends to be regulars who treat the space as a second home for both work and well-being. This is a separate company from the similarly named PORTAL studios elsewhere; The Portal House is its own Marin-based club centered on the intersection of focused work and restorative wellness.
