Marcus enjoyed making everyone laugh and smile. He had a huge heart of gold and would go out of his way to help anyone. He was an old soul who loved antiquing and garage sales. If there was a sale, he was there. He loved to collect old fans, radios, and military memorabilia. He was an avid collector of anything Xbox, especially 360 games and consoles, where HALO and Fallout were some of his favorites. Marcus was an avid tinkerer, often working on the antiques he would find and restoring them to their original glory.

Marcus was a simple man. We ask that those in attendance dress casually, as this is what Marcus would have wanted.
