A Slice of New York (ASONY) is a co-op (worker owned) pizza shop headquartered in Santa Clara, California. ASONY was co-founded by Kirk Vartan and Marguerite Lee. As a native of Manhattan, Kirk never found a pizza shop that honored what he grew up with when he moved to San Jose, CA for his job. ASONY was created to bring New York comfort food to the Bay Area. Today, ASONY is also focused on implementing structural and social change around worker co-operatives and employee ownership.

In 2017, ASONY became the first brick and mortar worker cooperative in the South Bay. As of 2022, the company boasts 15 equal owners in the co-op including Marguerite and Kirk. Since transitioning to a co-op, ASONY employee-owners can work towards their goal of being a progressive Bay Area business that supports its employees, community, and provides great food and customer service. Membership is open to all employees and is completely optional. 

Because ASONY is a co-op, the business is both owned and governed by the employees. Decisions are made democratically, where one member equals one vote. For ASONY, this means employees make decisions about workplace governance, annual budget, company direction and overall strategy. Because everyone is an equal owner, employees also share in the profits and risks of the company. While not all of their employees are members of the co-op, ASONY aims to foster an ownership culture.
