Proud to be a member of the Costello’s Ace Hardware team.

Colleen is always helpful, and went out of her way to get me a specific Valspar paint color that I found in a Lowe’s advertisement. I was so impressed by what she did for me.

Bill from the store is great as well, during the past busy weekend he took the time to discuss lawn products with me and then I came back this week to finish the conversation and Bill was not there, but Colleen was and she knew all about the situation and was able to pick up where he left off.
