Cleon Dunham

President Emeritus For Life

I founded ALRDC in 2000 when I retired from Shell. We have been active ever since, except for the time of the virus, with various Workshops, and other services to the Artificial Lift Community. I live two miles from my youngest son and his family in Wimberley, Texas, but right now we don’t get to see them as often as we’d like. My other two sons and their families live in Massachusetts and Colorado. We visit often but see them only now and then. But my daughter-in-law was recently in Belton, Texas to help my granddaughter move into her new home there and we got together to celebrate our Anniversary and my wife’s Birthday, with appropriate use of masks and social distancing. I am active in the Presbyterian Church in Austin, although these days we have all of our services via Zoom.
