Our Team


Jeffrey Pandolfino

Jeff began his career working alongside James Beard Award-winning Chef Norman VanAken, and later found his calling developing and operating growing high-end quick service brands Dean & Deluca, Cosi, & Pret a Manger. With his wife Cai, he opened his first business, Plum Pure Foods in 2003, selling the business before starting G&T in 2012. His love for developing simple, smart, operations serving sophisticated flavors in convenient format has driven his passion for the quick service business.  A creative and analytical thinker, Jeffrey is the savvy, hands-on entrepreneurial heart of the business.

Cai Pandolfino

Cai graduated from Dartmouth College in 1997 and began a career in management consulting with MCA. A lifelong passion for food brought her to Cosi, a fledgling QSR concept in 1999, growing as marketing director through rapid national expansion, merger, and IPO. With the sale of Plum Pure Foods in 2008, Cai joined Le Pain Quotidien, developing national catering programs and directing marketing & brand efforts in 65+ US stores, and franchisees in 17 countries. Her passion for creating authentic, mission-driven brands with uniquely differentiated value propositions brought Cai into the G&T fold  in 2011, where she works as the cerebral culture builder and storyteller.

Jeff & Cai live in Cos Cob CT, with their two green juice loving sons, Bennett & Coleman, and share a passion for baseball, yoga, Boy Scouts and church activities.
