Born in Broken Bow, Oklahoma, Bill was always fascinated with the instrumentation used to accurately measure land through valleys and over mountain tops.  After graduating from high school, he enlisted in the U.S. Army and specialized in land navigation.  After his 6th year of active duty, Bill entered the Delta Force program and excelled to the top of his class in land navigation. After his honorable discharge, Bill began seeking career opportunities where he started at Pinnell Survey, Inc. as an entry level employee, and soon worked his way up to Senior Crew Chief.  Now at The Pinnell Group, LLC, Bill is a key asset to our field crews.

Currently a student at Tarleton State University of Stephenville, Texas, Hayli also serves as part time receptionist and office clerk assisting her Dad at the Pinnell Group, LLC as time permits from her busy schedule.

Connor has always been eager to work in the field with his Dad to help locate boundary corners with the Shonsteadt and expose them with the shovel.  Holding the rod steady was a challenge, but experience makes perfection. After recently graduating high school in June 2019, Connor now works full time in the field and attends college courses in the evenings.
