I have been with Costello's ACE Hardware since 2008 and have over 45 years experience in the hardware business. I love spending spare time with my 4 grandchildren. I also enjoy playing and listening to classical music and am involved with 3 community bands.

After shopping at your store I will likely never go to Home Depot again. My shopping experience was wonderful. Everything I needed was at the store which was designed and organized very well.

Mr. Smilowitz not only executed my purchase transactions, but took the time to walk me through what I needed, explained the necessary mechanisms, and ensured that I was fully comfortable with my purchases. Due to the nature of my remodeling, it was necessary to visit the store on more than one occasion, and generally I am an individual who asks a lot of questions, and challenge most things also, a trait that most vendors may find a bit daunting, if not annoying, but Mr. Smilowitz never dipped in his Customer Care, and met me head on, step by step, consistently gracious, accommodating and exceeding my expectations.

Garden City Park is the very best hardware store I have ever been to. They are extremely helpful. They don’t just point when you ask for a product; they take you to the product and go above and beyond. I have been in there before while they were with irate customers and they handle things very professionally.
