About Proof Lab

Our favorite pastimes are surfing, skateboarding, music, art & the outdoors, so that’s what our shop is all about. We opened our doors in 2004, in a 600 sq.ft.  side-alley, and over the years have grown into the largest surf & skate shop in the Bay Area.
Our mission is to build an alternative retail model to the typical mall, one that is more interactive, sustainable, and focused on community building. Some of the ways Proof Lab has pursued this mission include:
  • Helped incubate a number of independent local businesses within our walls by providing space and marketing support, including:
  • Magic West Music School (on site music lessons)
  • Big Dog Surf Camp
  • I Heart Skateboarding (Skate lessons/camps)
  • Pat Judah Ding Repair (Custom surfboards and repair)
  • CNL Native Plant Nursery (& Native Landscaping)
  • Mill Valley Potter’s Studio (Ceramics Studio)
  • The Little Art Studio (Toddlers Art classes)
  • Equator Coffee Shop at Proof Lab
  • Long history of supporting top surfers/skaters, artists, local schools and non-profit organizations
  • Putting on unique community events such as surf & skate contests, film premiers, art & music shows, and sustainability workshops
  • Have always had a public skate ramp of some sort on site
  • Certified Green Business since 2007
  • Built the shop with mostly re-used/reclaimed materials
  • Membership-based Biodiesel fuel station on site (made from locally recycled veggie oil)
  • Stock as many local/sustainable brands as possible. Patagonia is our #1 brand overall and we always give the local kids making tees a shot.
  • Co-founded GROW Art & Garden Education Center by revitalizing an adjacent vacant lot with our neighbor businesses Alpha Dog. 
  • 100% Product Take-Back Policy – any item purchased from Proof Lab can be returned in any condition at any time for a partial store credit, and Proof Lab will recycle it.
