Our Team

Mathayom Vacharat is the owner and head chef at Mathayom Private Chefs and St. John mat-2Catering at Windy Level and has been a resident of St. John since 1995, moving from Philadelphia after graduating Drexel University with a Business degree. Mat then attended the Graduate Program at the School of Hard Knocks, studying Improvisation.  Opening the business in 2004, his experience as executive chef at premier fine dining restaurants on St. John lends his cuisine a breadth of influences ranging from Asian Fusion to Progressive American to Caribbean Flair.

Mat is committed to sourcing fresh local product as he and his team of talented chefs create custom menus based on seasonal availability. He and his chefs support the Gifft Hill School’s EARTH Program, sourcing much of their local product from the student-run gardens. This approach breeds an innate flexibility when approaching vegetarian, raw food, and other restricted diet menus, as well as creating custom menus for clients interested in an “island to table”approach.

In 2016, Chef Mat and his team began executing Full Moon Dinners at their modest catering venue, changing the theme every month and collaborating with local distributors to create the perfect drink pairings for the multi-course affairs.  Continuing with the theme of fresh and local, they have cultivated and maintained a small garden, drawing product from it whenever possible, and are the first business on St. John to become Reef Responsible certified.
