He received his DO from Oklahoma State University and became a Family Practice Physician, practicing for 10 years in Oklahoma. During this time, he met and married the love of his life, Martha Henson. To their union, two more children were added, Sarah and Elizabeth. He then joined the Navy as a flight surgeon, honorably serving for five years. He was transferred to Pensacola and then finally Mississippi with the Navy, earning the rank of Commander before being Honorably discharged. After his military service, he worked as a Family Practice Physician for 30 more years. He loved his job and cared for all of his patients dearly. Throughout his life, he lived as though there was nothing he could not do. He did everything big and over the top. He thought he could be a professional at everything. Dr. Kiehn received his private pilot’s license and owned two different private planes. He would fly his family to various locations just for fun. He loved boating - house boating, ski boating, and bass boating. He also enjoyed golfing, fishing and hunting. Dr. Kiehn had horses and tried his hand at cutting horses for a few years. He also did trail riding with his family. He was licensed in scuba diving and was on a scuba diving team that would travel for spear fishing. He was a snow skier and a water skier. He loved motorcycles, and he would spend his off time in his barn and shop, working on motorcycles and cars. He also took painting lessons and violin lessons. Later in life, his body started to fail him and he had to slow down quite a bit. He and Martha relocated to Purvis, Mississippi, to be closer to their daughters. He spent his time on his back porch with his dogs (whom he adored), riding in his mule, working on his tractor, and watching movies. He adored his grandchildren and would constantly say “look at what we’ve created, look at what I’ve done” when watching them.
