When you become a sustainer, you are making a monthly commitment of financial support. Each month, we will charge your credit or debit card or withdrawal from your checking account the amount you specify. Your Sustaining Membership will automatically renew each year unless you choose to cancel or change it. You can change or stop your donation at any time by calling us at 713.313.1909. Sustainers are valuable to providing a continual base of community support that we can rely on, so you can continue to rely on KTSU.
