About Us

Alice Kastelic began operation as Sooner Tax Service in 1970. Over a span of 20 years, she grew her business from about 200 clients in 1970 to a little over 1,500 clients by 2009. In 2009, founder Alice Kastelic passed away from stroke-related illness. Many of her long-time clients speak of how she saved them money in taxes year after year, stating that she was a great lady and will surely be missed. Since Alice’s death in 2009, daily operations are under the guidance of her son, Bruce Kastelic.
