While in high school he participated and lettered in football, basketball, and baseball.  He also sang in the high school choir and was crowned Homecoming King.  He graduated from Lake Benton public school in 1955 and continued his education at South Dakota State University in Brookings, South Dakota (go Jacks!).  On June 6, 1960, Dave graduated with a Bachelor of Science degree in Pharmacology and became employed as a pharmacist at Vadheim Drug in Tyler, Minnesota.  On October 6, 1962, Dave married the love of his life, Elizabeth Schardin at St. John’s Lutheran Church in Lake Benton.  The couple made their home in Tyler, where they raised their four children.  In 1982, Dave and Liz purchased Vadheim Drug and renamed it Koster Pharmacy.  In 2010, after more than 50 years serving the community of Tyler, the couple sold Koster Pharmacy to Thrifty White.  Dave continued to work as a relief pharmacist from 2010 to 2018 for Thrifty White, Olivia Drug, Siverson’s Pharmacy, and Shopko.  He officially retired in 2018 at the age of 81.  Dave was an active member of both First English Lutheran Church in Tyler and First Lutheran Church in Marshall.  He served the community of Tyler in several capacities.  He was a Church Council President at First English as well as a member of the church choir.  He also served on the Tyler School Board, the Tyler Hospital Board, the Tyler Golf Club Board, and the Aebleskiver Committee. He was a member of the Tyler Lions Club and the Chamber of Commerce.  Dave also performed in many of the Lion Club plays.  He absolutely loved to golf and was instrumental in the development of building the new club house in the 1970’s.
