About Kim

Kim was born in Vermillion, South Dakota, and is a 4th generation attorney. Her father grew up in Bonesteel, South Dakota, and her mother in Boston, Massachusetts. Her father went into nationwide commercial real estate while her mother raised Arabian horses. Kim has two children who are attending University of Colorado at Boulder. Kim’s husband Jon owns a distillery in Golden, Colorado, which enables him to be by far the more interesting of the two. Kim and her family enjoy developing the homesteaded family ranch in Bonesteel, South Dakota, which sits on the Missouri River along the route of the Lewis and Clark Expedition, and snorkeling at her “beach shack” on Grand Cayman, where she serves as Treasurer to the Cayman Kai Property Owners Association. In her “free time,” Kim enjoys creating graphic drawings, usually of her children, listening to every audiobook ever recorded, hiking while collecting wildflowers (to keep busy while hiking), and reading 365 Tao every day to keep sane.
