I have been with Costello's since 2011 when I was hired as a sales associate in Northport. When I am not working I enjoy spending time with my family, kayaking and playing baseball.

I want to compliment the very nice, helpful sales associates at your Nesconset store. This Mother’s Day I was met with very respectful young men who were knowledgeable and polite.
Sincerely, Kim H.
