Matt was always present for his family and friends and did everything with great love and compassion.

Matt was a proud Milton Redhawk Band parent and made a great waterboy for all of the parades. He enjoyed taking his son to LA Lakers and Bucks games and was blessed to witness his son's wedding in May. For ten years he and his daughter would dance the night away at the Daddy Daughter Dance and he was so proud of her as she earned her Pointe Shoes in Ballet. She will always be a daddy's girl. He never once forgot about his very own angel Shea-Tate. Matt and his family would volunteer and donate in his memory as Team Shea-Tate.
