John Gregory Glenn, 68, left this life on May 16th at St. Francis Hospital, Tulsa Oklahoma as a result of Diabetic Ketoacidocis. He was the son of John Edward Glenn and Patricia LaVange Siegle, formerly of this city. He headed the Glenn Mortgage Group in Austin, Texas, served Alethes LLC Mortgage Lender and Amerinet Mortgage as EVP from June 1999 to April 2009 and was a member of the Williamson County Association of Realtors. He was a cancer survivor and said that he loved people, never encountered a stranger. He was known as Johnny Rocket, and a favorite line was "You know more than you think you know, believe it, use it.?? Do it!" Among the things he loved to do was play golf and fish. He is survived by his brother, Russel Linn Glenn of Jenks, OK, one daughter Stephanie (Glenn) Beringer, and several cousins. He was preceded in death by his mother. As was his wish, his remains were cremated.
