Stephen was born in Pasadena, California on September 4, 1963. He graduated from McCullough High School in The Woodlands, Texas, and continued his studies at Stephen F. Austin State University in Nacogdoches, Texas where he earned his associate degree.
Stephen married Brenda Kay Nesmith on April 17, 1998. Stephen and Brenda celebrated 28 years of marriage earlier this year, a testimony to the love and devotion they shared. They raised their son and daughter together in a home filled with warmth and laughter, and in his later years, he found great joy spending time with his grandchildren.
Stephen enjoyed a long and successful career in the mortgage industry working for Savings of America.
Stephen was a proud member of TKE (Tau Kappa Epsilon) where lifelong friendships were formed. He also enjoyed music, Disney, sports, racing, and cooking. Nothing made him happier, however, than spending time with friends and family.
Stephen was preceded in death by his father Carl John Cos, his grandparents Wayne and Ethel Christy, and grandmother Cheena Cos.
He is survived by his mother Judy Cos-Murray; his wife Brenda Cos; daughter Chelsea Cox; son Chase Cos; grandchildren John Hyde III, River Cox and Jackson Cox; brother David Cos and his wife Kathleen Cos; and his nieces Christina Rogers and Ashley Cos.
