Scott Plath – Owner

Scott Plath along with his wife Kathy own Moonstones their second regionally successful restaurant venture, the first being Cobblestones of Lowell (  In addition, Scott also looks to extol his passion for fine food, and hospitality, he writes a humorous "restaurant insider" weekly blog, ( and a regular column for Merrimack Valley Magazine ( entitled "A view from the kitchen".

Early Years
Beginning at age 13 as a dishwasher in NY, Scott fell quickly in love with the restaurant business.  He worked his way from the kitchen to the front of the house, first as a busboy, then as server, and personal favorite, bartender.

Education and Partnership
His continued interest led him to UMass Amherst, where he majored in restaurant management and met his future wife Kathy.  His senior final project, in both high school and college, was to create a restaurant concept and it was no coincidence that he ended up at UMASS with "The International", a globally themed restaurant featuring the best cuisine from a variety of cultures.

The inspiration then, as now, was preceded by years of exposure to a diverse and ethnically-rich culinary foundation while growing up in New York.  In 1993, Scott decided he was all done working for others and committed to take the leap into ownership.  His 1st restaurant, COBBLESTONES, (opened on June 6, 1994 and immediately began its rise to the top of the Merrimack Valley restaurant scene, where it has since solidified its status as a consistent, and respected culinary and community leader for nearly 18 years and counting.

Entrepreneurial Expansion
While COBBLESTONES maintained its reputation of excellence, Scott and Kathy never stopped looking for the right opportunity to open a second restaurant.  Through continued "research and development" in Boston, NYC, Washington, Baltimore, Chicago, Miami, Paris, and Prague the concept of moonstones was born.  Many hours of heated debate and sampling with a team of chefs at COBBLESTONES finally forged a collaborative menu, while Scott's father-in-law supervised the demolition of the "Old" Ground Round in Chelmsford.

Scott, Kathy, and daughters Aislyn, Tara, and Kelli are thrilled at moonstones success as they approach a 4th anniversary, providing the local community a progressive, quality and dynamic "urban dining experience" while contemplating the next venture!


Robert Jean – Executive Chef 

Executive Chef-Partner Robert Jean has long envisioned returning to create culinary excellence in his childhood “backyard” of Tyngsboro, MA

After the last 12 years of conceiving and directing award winning food, exceptional service, and culinary innovation in numerous Boston restaurants, Chef Jean has selected Moonstones in Chelmsford as his new home, thrilled to raise the gastronomic bar in the Merrimack Valley.
In 2000, Chef Jamie Mammano of the Columbus Hospitality Group, handpicked Robert to join the team at Mistral—a soon-to-be Boston landmark.

Chef Jean flourished as Executive Sous Chef and it was passion and enthusiasm for the business that, in just three years, led next to his overseeing a restaurant from the ground up.  Jean went on to lead all aspects—including décor and the selection of flatware to overseeing all staff selection and training—of Columbus’ newest venture, Teatro, a rustic Italian neighborhood bistro.  As the restaurant’s Executive Chef, Jean created great success before he would be called upon to open another restaurant, Mistral’s “kid sister”, Sorellina—since called the “finest of the Boston dining scene”.  As Executive Chef and partner of Sorellina, Chef Jean likewise directed the opening of the next Columbus Group success-Burlington’s L’Andana, only two years later.

Through the years, from California’s Wine Country to Tyngsboro’s 5 Diamond rated Stonehenge, Biba, Aigo Bistro and beyond, Chef Jean has had the opportunity to work for, or alongside, some of the most talented chefs in the country while receiving widespread accolades.  Beyond Mammamo, Robert has worked and/or collaborated with iconic Lydia Shire, Rob Evans, Marc Orfaly, and Tony Souzi.  In 2009, Chef Jean took home 1st prize with his “Best Buddy”, during this annual charitable event for challenged youths, “defeating” other notable chefs Michael Schlow, Lydia Shire, Barbara Lynch and Daniel Bruce.

In 2007, Jean was invited to cook at New York City’s James Beard House.  Jean’s Sorellina was voted “Top 50” Boston Restaurants for 4 years in a row and “Best Italian Restuarant”, by Boston Magazine while receiving 3 ½ stars from Boston Globe and The highest Zagat Rating in the city for 6 consecutive years!
Yet, Chef Jean’s proudest achievement?  The ongoing education afforded aspiring culinary professionals, while sending them on to successful careers in the restaurant industry.
