I've been with Costello’s four and a half years. My strengths are in our paint department. In my past before Costello’s I ran several Benjamin Moore paint stores about 25 years. I like to help people problem solve and get them what's needed for their given projects. I spend my weekends with my wife and daughter who plays travel softball. When I'm not on the softball field you will find me surf casting. I'm an avid stripe bass fisherman.

Kathleen was extremely helpful in assisting me in selecting paint for my room. She was very professional, courteous and sincerely interested in making sure that I would be happy with my decision. Thanks to Kathleen, I will now utilize Ace as my source for paint, in addition to the traditional items that I usually buy from Ace.

I am writing to commend one of your sales personnel, Kathleen Stephens. We were out of our home for sixteen months after Super Storm Sandy and were in Costello’s Ace Massapequa store at least once a week if not more during the duration of that time. I failed to note the paint color which I loved and was in the store several times a week to try to figure that out. I know in the large picture of things this was a minor problem, but I think was the culmination of many months of trying to weather the storm and I was exhausted. Kathleen noticed that I was wearing a heart monitor on one of those occasions, never mentioned it as she is a true professional, but took my plight to the Benjamin Moore Rep, trying to get some assistance in finding the right color. The Rep told Kathleen to tell me not to spend any more time (or money) or angst buying samples because they would gift me two free gallons of the color of my choice. It was so refreshing that someone would take time to notice and think of being kind and compassionate to their fellow man. Kathleen is extremely professional, knowledgeable, and courteous while always having a smile on her face.

George had tremendous customer service and he went out of his way to fix and clean our garden light fixture. The whole store is phenomenal and I will only shop at Costello’s!
