All CASTO Events have been canceled through September 2020 due to the COVID19 Pandemic.
Please choose your membership level you wish to sign up for. This is available for Individual, Agency or Sustaining membership. During the sign up process, you will have the opportunity to opt-in to be listed in the directory online. You may also include a photo of yourself. Once you complete the application process, you will receive an email upon approval.
If you want to pay for your membership with CASH or CHECK, choose the "Invoice Me" option. Mail a copy of the Invoice along with your payment to the CASTO Treasurer. If you would like ten or twelve equal payments deducted from your paycheck, choose "Invoice Me". Once the CASTO Treasurer has received your first check from your Payroll Department, your membership will be activated. You will be informed via email once this has occurred.
