About East Center Market

East Center Market, also known as “Eastside Market”, has been a fixture in Wallingford for many years. We are a family owned and operated grocery store committed to providing excellent customer service, along with the freshest cuts of meat, tasty deli options and beautiful produce to our valued customers.

East Center Market’s owner, Bill Kowaleski, Sr. has worked in the food service industry ever since he was a teenager. He worked for his father’s catering business, as he began his four-decade long career as a butcher working in a local grocery store. In 1989, he went to work for East Center Market as the Store Manager and Head Butcher. He left in 1996 to explore other opportunities and in 2006, Bill’s dream of owning his own grocery store became a reality when he and his wife Vicki purchased East Center Market. Family comes first and foremost with Bill and Vicki. Not only has Bill’s mother Jayne worked for East Center Market over the years, but each of their four children, Bill Jr., Sarah, Kris, and Kylie have also worked at the “Eastside” icon.

Bill’s daughter, Sarah Kowaleski Lorusso began her ECM journey alongside her father in 2006. In 2009, she graduated from Southern Connecticut State University with a Master’s Degree in Marriage & Family Counseling, stepping away to pursue her career as a therapist. Much like her father, Sarah realized her heart belonged to East Center Market. She took on the position of Store Manager in 2014. Shortly thereafter, in 2018, Sarah’s husband Donald joined the family to work at ECM after several years working for the State of Connecticut.

The Kowaleski family strives to provide services in a friendly, helpful manner. We would not be where we are today without our wonderful customers and dedicated employees!
