David J. Costello

So sorry to hear of David's passing. I am a fellow Buff State alum and a member of his old student political party at school, Positive Outlook. I was a USG senator with him and interacted with him mainly that way. Always kind and positive and a great leader. Too soon, rest in peace my friend!

Joanne, I am very sorry for your loss. I did not know David. However, I had prolonged contact with your family for many years through my daughter, Laurel. The Costello home was infused with laughter, smiles, and love. May David´s spirit bask in the light with which he lived. Constance Belsi

David was a thoughtful, intelligent, beautiful person and will be missed by many. My condolences to his family. RIP.

I will so miss our talks in the middle of the night when neither of us could sleep. We would check Facebook and see that the other was on and so it began.

David was one of my classmates at Mott Road Elementary. He was one of the smartest kids I knew.
