Jeffrey Osowski, General Manager

Jeffrey Osowski is the General Manager of Harvest Restaurant in Cambridge, Massachusetts.

Since starting in the hospitality industry at age 15, Osowski, a native of Connecticut, has worked in almost every position in both front and back of house. Early in his career, he pursued his passion for art and music as a recording musician, performing throughout New England.  While studying theatre and arts in college, however, he decided to pursue his love of hospitality full time and has since spent his entire career in hotels, casinos, catering and restaurants.

In 1992 he joined Foxwoods Resort & Casino where he worked as a server, opening three restaurants over the course of eight years. In 2000 he transitioned to Morton’s Steakhouse where his management experience began. He served as Assistant General Manager for one year and General Manager for two years, during which he managed three different cities including Washington D.C., Boston, and Hartford. In 2004 he received the “Team Excellence” Award out of more than 60 candidates due to his positive work environment and low percentage of employee turn-over throughout the entire company.

The following year Osowski returned to Boston where he joined Smith & Wollensky as a lead server. In 2008 he took a position at Grill 23 & Bar – sister restaurant to Harvest and part of the Himmel Hospitality restaurant group – where he worked as a server for more than seven years, developing a large and loyal following of guests.  In 2016, with a desire to return to management, he joined the team at Harvest.  In his current role Osowski leads the service staff training and development effort and particularly enjoys the challenge of building a strong service-oriented team.

Livsey gained national recognition for his exquisite talents and creativity on Food Network’s Holiday Baking Championship in 2017, where he finished as a finalist in the nation-wide competition.

A Rhode Island native, Livsey began his pastry career in his home state at Johnson & Wales University,where he spent four years discovering his passion and honing his craft in all things pastry. Prior to joining the team at Harvest, Livsey worked his way up to Head Pastry Chef at Shelter Harbor Golf Club’s fine dining restaurant and held the position of kitchen manager at Sweet Indulgence bakery in Cranston Rhode Island. In 2011, he launched his own custom-made cake business, where he further developed his skills in the art of specialty and wedding cakes. After a stint at Four Seasons Atlanta, Livsey returned to New England to helm the dessert and bread program at Harvard Square’s acclaimed Harvest restaurant where he has held the title of Executive Pastry Chef since 2016.

When he’s not in the kitchen or experimenting with new flavors at home, Livsey enjoys taking his dog for a run and spending the afternoon on the beach with friends and family.
