Jim Hutmacher, CWD/PI, sales engineer with Wyo-Ben Inc., was born and raised in the Chamberlain, South Dakota area and began his career in the water well industry at an early age. When he was growing up, he would spend all his spare time either at the rig or at the shop helping his father and uncle. He has always said that he could run a drilling rig before he could legally drive.

Hutmacher graduated from Chamberlain High School and attended the University of South Dakota. Eventually he was at home helping with the well drilling business. He became interested in learning more about water wells and began to attend the state association meetings, and then NGWA conventions.

A South Dakota-licensed well driller since the mid ’70s, Hutmacher took the NGWA voluntary certification test in 1986 for mud rotary, and the pump installer test in 1993, and is an NGWA Certified Well Driller/Pump Installer (CWD/PI). He has served on the South Dakota Water Management Board, which licenses well drillers and pump installers and issues water use permits, from 2003 to the present.

Hutmacher has been employed with Wyo-Ben Inc. since 2016 and is currently a sales engineer. His responsibilities include training for customers and distributors, in both classroom and on-site settings. He specializes in the fields of water well drilling, environmental, and HDD. His territory covers eight states in the upper Midwest. Hutmacher has instructed classes on drilling fluids in the eight states in the Midwest region and at NGWA’a Groundwater Week 2018.

Prior to entering the civilian workforce, he had a prestigious military career in the 3rd Marine Division where he earned a meritorious promotion to the rank of Sergeant and the Navy and Marines Corps Achievement medal for outstanding performance while serving abroad. After completion of his tour in Afghanistan, Lyle continued his military service in the Georgia Army National Guard while simultaneously earning a B.S. degree in physiology and a B.A. degree in criminal justice from the University of Georgia in 2006.

Terry Christine, partner in Jackson Geothermal, has been in the drilling industry for several decades. In 1978, Jackson and Sons Drilling and Pump Co. was founded by Dan and Nora Jackson as a family-owned and -operated water well business. In 1998, their oldest son Jim purchased the company and started Jackson Geothermal. He grew Jackson Geothermal to being the largest family-owned and -operated geothermal and drilling company in the country having 15 drill rigs running all the time and 60-pllus employees. In the early 2000s, Jackson Geothermal covered the entire United States, drilling both commercial and residential geothermal. Having started in the drilling industry in 1992, Christine became an employee at Jackson Geothermal in 2000. In 2015, Christine and Jackson became partners and are still running Jackson Geothermal together to this day.
