After opening his first shop in San Rafael in 2005 and another in Napa two years later, organic ice cream purveyor Neal Gottlieb finally has a presence in the city. On Friday, the lucky third outlet of Three Twins ice cream opened on Fillmore in the Lower Haight.

A former Peace Corps volunteer who once worked in Morocco, Gottlieb named his company for the nickname given to an apartment he once shared with his twin brother and wife, also a twin. Gottlieb is passionate about more than just ice cream: He offsets Three Twins' carbon emissions, composts, and uses only organic ingredients.
