• fax-in
• drop-off
• online registration (you will need to get a user name and password by calling the registration office at 720-977-5901).

Due to the popularity of the swim lesson program, this registration is conducted separately. For a list of our current registration dates and times please visit our online Thornton Activities Guide.
