Erin O’Neal Fiehler, age 44, of Kirkwood, Missouri, died peacefully in her home on February 29, 2024, after struggling with a debilitating illness for many years. She was born in Chesterfield, MO, on July 3, 1979, to Dennis and Judith (Hightower) Fiehler and was a dearly cherished daughter, granddaughter, sister, sister-in-law and aunt, and had many dear friendships.

Erin was a 1997 graduate of Lindbergh High School, and a graduate of Webster University with a major in math. A highlight of her early life was living in Athens, Greece, with her family for three years and attending elementary school at the American Community School. After college she worked as a research assistant in her brother’s company, Infuz, for several years. Erin was a Christian of the Methodist faith.

She is survived by her parents of St. Louis, MO, her brother Jason Fiehler and sister-in-law Katie O’Dell of Kirkwood, MO, and her beloved nephew Connor Fiehler of Nashville, Tennessee. Erin had a special relationship with Connor who always played his guitar whenever he visited her.

She was preceded in death by her grandparents Edwin and Wanda Fiehler, David and Lucie Hightower, Sr., and her uncle David Hightower, Jr.

The love of Erin’s life was her faithful Chihuahua companion for 18 years, Miss Trina.
