Please Note: The online registration process has changed. Advance CTE no longer accepts credit card payments at the time of registration. You will receive an invoice via email within one business day after submitting your registration. The invoice will provide a link to pay securely online using a credit card or bank draft. We also accept payments by check. Please mail check payments to 8484 Georgia Avenue, Suite 320, Silver Spring, MD 20910. If you have any questions regarding payment, please call Krissy Haynes, Event Planner, at 301-445-2780.
