A few words

About Us

Janssen's Market has been a Greenville landmark since 1952 thanks to the dedication of three generations of Janssen family members. Janssen's provides a relaxing, friendly environment where customers pick-up the necessities, talk to the butcher about the best cut of meat for an upcoming dinner party, or work with the florist to develop the perfect bouquet. At Janssen's, you're part of the family!

Founded by Joseph Janssen Sr. in the fall of 1952, Janssen's has become an institution in our community. We offer the finest foods and superb customer service, with the highest attention to detail in everything we do.

When you step inside our doors, you'll find a complete range of gourmet products as well as everyday items. There's no need to shop anywhere else! And, if we don't have it, just ask and we'll get it for you!

Stop in for lunch or dinner at J's Cafe. Visit our butcher to peruse a mélange of fresh meats and seafood. You'll be more than satisfied with our selection of produce, including greens and herbs straight from organic farms.

Our catering service will impress you with superior hors d'oeuvres, entrées, salads and trays created with produce, meats, and cheeses found exclusively in our store.

We have dedicated ourselves to serving our community. Come visit us!
