Mark was a very devoted and loving husband, father, grandfather and brother. He loved golf, photography, astronomy, and his second home in Florence, AZ where the weather was warm and the sky was clear. He was a generous man and will leave a legacy of love, humor, generosity, kindness and helpfulness. Mark would help anyone and would have given his last dollar if someone needed it.
