Mary’s Pizza Shack, a Sonoma, California-based Italian eatery with 18 franchises across Northern California, is celebrating its 50-year anniversary by opening a new fast-casual restaurant concept.

Later this year, Mary’s Pizza Shack will launch a new company under the leadership of Cully Williamson, the grandson-in-law of founder Mary Fazio. Williamson will lead the development of the new fast-casual concept, which will offer a fresh menu of contemporary Italian cuisine, with many of the items prepared in a central brick oven, including roasted chicken and other meats, and a new take on the company’s signature pizzas. Inspired by recipes from Mary’s Pizza Shack, the new restaurant will continue the tradition of dishes made fresh to order, with sauces, pizza dough, salad dressings, and focaccia made from scratch.

“This project has been in development over the past year or so, and I’m excited to be able to focus on it full-time,” Williamson said. “It’s really a concept that the family has worked together on, and I’m looking forward to transforming our vision into reality.” Williamson previously served as CEO of Mary’s Pizza Shack, and has been part of the company for 28 years. He will continue to serve on the board of directors for Mary’s Pizza Shack, and will have significant ownership in the new corporation. Similarly, Mary’s Pizza Shack will retain majority ownership of the new corporation, allowing the new concept to grow independently while maintaining strong ties to the family.

Fazio’s grandson, Vince Albano, has been selected by the board of directors to replace Williamson as CEO of Mary’s Pizza Shack. “I’m truly honored to take on this role in the company,” Albano said. “Mary’s is a family company in every sense, and we have a great team in place.”
