    I am so very sorry for the loss of my 2nd cousin, I never met Matthew, but I know his Mom & Dad, and aunts, and they can’t enough about the wonderful qualities he had.
    One of his treasures was animals, so I went on the Shultz’s Guesthouse website.,provided for donations and got a glimpse at what Matt cared about & loved.
    I love dogs and all animals, so it tugged at my heart. His father Dan ( Danny to me) lol. told me the other day Matt was alot like him, when he was young. Well, that did it for me! I loved Matthew instantly…My love goes out to his brothers, sister and girlfriend. I pray you have the comfort of a calm mind and peaceful heart, with all the prayers from your family and friends.
