About Us

Adam Greenberg

Founder and President, Restaurant Zone, Inc.

Adam Greenberg, a lifelong Marylander, is the owner Principal behind Potomac Pizza, Potomac Village Deli Catering and Bagels ‘n Grinds. He has locations in Potomac, Chevy Chase, Gaithersburg, Rockville & Arundel Mills.

In addition to ensuring that his neighbors are well fed, Adam has been ‘giving back’ to his community in many ways. He is known to hundreds of Montgomery County school children as “The Pizza Man,” due to the numerous Pizza Demonstrations he has given at elementary schools. Adam teaches kids about cleanliness in the kitchen while helping them to make their own pizzas to bring home for dinner. Since the inception of Bagels ‘n Grinds, he has donated tens of thousands of bagels to Ft. Meade, Autism Speaks and countless others just to name a few.

He was recognized as the Potomac Chamber of Commerce Business Person of the Year 1998/9 as well as 2002/3. Adam was also recognized as the Service Guild Business Person/ Partner of the Year in 2000, as well as awarded the Cabin John Volunteer Fire Department Community Partnership Award in 2003.

He has been a member of the Board of Directors for the Potomac Chamber of Commerce since 1997, was the Treasurer of Chamber 1998-2002, and for the past several years served as President. Adam had been on the Board of Directors of JSSA (Jewish Social Service Agency) and on the Board of Directors of Shady Grove Hospital Foundation and currently the vice Chair of Bullis School board of Directors.

Adam’s history in the restaurant business began in 1992 when he opened his first establishment, the Cone Zone of Bethesda in February 1992. In March 1994, he opened the Cone Zone in Potomac. It wasn’t long before Adam made the connection between pizza and ice cream, and he purchased the original Potomac Pizza in June 1995. Adam sold Cone Zone of Bethesda in 1996, sold Cone Zone Potomac in 1997, and opened Potomac Pizza/Cone Zone Kentland’s in 1999. He bought Potomac Village Deli in February 2002, opened Potomac Pizza Traville in January 2003. He went onto open his Chevy Chase location in June 2006, and then opened his first Bagels ‘n Grinds in April 2012. Adam is planning on opening Potomac Pizza & Bagels ‘n Grinds in the Fall of 2016.

Adam lives with his wife Courtney and their three children in Potomac, Maryland. They eat either pizza or bagels basically every day. Adam enjoys travel, boating, cars, sporting events and spending time with his family.

Sam Lerner

Managing Partner

Sam Lerner was born and raised in Baltimore where he worked for some of Baltimore’s finest delicatessens and caterers during his high school and college years. In 1975, Sam opened Olney’s The Village Deli, a kosher-style delicatessen and restaurant inside the Village Pharmacy. Brisk business led to a larger storefront and a new name: Potomac Village Deli. In 1997, after years of imagining himself on the big screen, Sam sold Potomac Village Deli to pursue a career in acting. Unfortunately, after taking one look at Sam, Hollywood sent him right back to Maryland. Adam Greenberg, who bought the deli in 2002, convinced Sam to come back as managing partner. Sam lives in Rockville with his wife, Robin, of 40 years and two cats. He enjoys playing softball (as long as he can still see the ball), watching his favorite television stars Larry, Moe and Curly and his favorite movie star, Wile E. Coyote.
