Ron Lingenfelter
General Manager
We usually feature one of our great employees here, but some of you have asked about me. I would rather brag about the other guys but here goes. I have been married for 40 years to Bette. We have 3 great kids. My son Ryan is married to Lisa. They live in Omaha where Ryan works in sales and marketing dental equipment. My daughter Amber is married to Brian King. They have 3 children. My daughter Ashley is married to Preston Frasch and they have a son and daughter. My daughters own Uprooted Boutique.
I have worked here since 1978. I worked my way through college at Northeast Community College, and graduated from there in 1981. In 1986, I took over management here when my brother had his accident. I serve on the ATRA (Automatic Transmission Rebuilders Association) International Board of Directors. Currently, I serve on the Midwest Chapter Board of ATRA. My hobbies in my spare time have changed from auto racing, which I did for many years, to woodworking. I enjoy racing now as a spectator. Our family enjoys camping. I also belong to two Bible study groups and enjoy that. My real passion has always been my kids. Now that they have grown up, I am looking forward to furthering my passion with grandchildren. I have 4 granddaughters and 3 grandsons, and I have to say that being a grandpa is one of my greatest thrills.
