Jeffrey John Giesman was born on June 21, 1971, in Knoxville, the son of John and Sharon (Eisenhauer) Giesman. He graduated from Buffalo Center Rake High School with the class of 1989. During high school, he was a member of 4-H, FFA, Boys State, band, chorus, and golf.

Jeff then went on to graduate from Iowa State University in 1993 with a BS in Ag Business. It was during college that he met his wife, Vanessa Macklin. He started his career in seed production at AgriPro Seeds in Ames. He then took a sales position with AgVenture Seeds in Hampton. With this move, he proposed and married Vanessa on July 27, 1996. Jeff earned his Certified Crop Adviser Certification and became an Agronomist.

Over the years with his other loves of his life, hunting and fishing, Jeff and Vanessa added their daughter Kylie to their family, adopting her at two days old. Kylie was the light of his eye, and she had him wrapped around her little finger!

Jeff was an active member of the Clear Lake Fishing Club and served as vice-president for many years. He always loved the Kids’ Fishing Derby and the Walleye Classic. He was also a member of the Titonka Gun Club, enjoying trap-shooting for team Brandt Stump Removal.
