Membership is on a company basis. Accordingly, we encourage active participation by ALL company employees who may benefit from membership, including tax (property and unclaimed property), finance, legal and government affairs professionals. Be sure to check your company’s listing to make sure all interested people are included. If you have additions, please have them sign-up on the COST website. We want to ensure that you are getting the most out of your COST membership and are taking advantage of everything COST offers. If you have questions, please contact Judy Slotnik.
