Gregory Brian Diehl was born January 22, 1957 to Colleen and Leonard Diehl in Oklahoma City, OK. After a brave battle with illness, he left us to join his Creator on July 2, 2011. Greg was an exceptionally devoted father and is survived by a beautiful daughter, Chelsea Elizabeth Diehl, of Edmond, OK. He is also survived by Mark and Judy Diehl; and Steve Diehl of Oklahoma City, OK. Gregs second love was his guitar and he enjoyed playing, whether alone or in the midst of fellow musicians. He loved all animals and will be missed by Riley and Emmitt. Sailing also played a significant role in his life and Greg enjoyed participating in numerous Regattas over the years. In more recent years, he proudly supported his daughter in her volleyball athletic programs and events. Gregs life will be celebrated at All Souls Episcopal Church on Wednesday, July 6, 2011 at 1:00 pm. In lieu of flowers, contributions to Skyline Church in Oklahoma City are requested.
