Whole Foods Market Noe Valley
~175 active Team Members
~4700 labor hours per week to operate the store
~ 720 shifts per week
~ 30,000 SKUs within the store, with 17k square feet of retail space
~ 70% of our Team Members commute through public transit or bicycle (rough estimate)
NOE is open for business 5076 hours of the possible 8760 in each calendar year!
Smallest retail square footage WFM in SF, consistently in top-ten for sales per-square-foot in the entire company
