welcome to st. thomas the apostle parish in
crystal lake, Illinois!
Welcome to our parish! The best way to get involved in parish life is to register for our parish. You can do that one of two ways:
If you would like to register online, please click the Register Now button below.
Please note:
- Register online
- Register in person
If you would like to register online, please click the Register Now button below.
Please note:
- You can only be registered at one parish, so if you have moved from another parish and were registered there, please contact your previous parish and let them know you've moved!
- We use Planning Center Online for registration for Religious Education, Youth Ministry (including Confirmation), Adult Education and various events & activities, including Sunday Masses during the Covid-19 Pandemic. When logging on to register, please click "Add someone else" at the bottom of the page and repeat for all members of your family. It will seem like a lot to do, but once you do it this first time, it will be very easy to go back in and register for other programs and events because everyone in the household is already in the system!
- When you go into PCO it will ask to send you a code. You can have the code sent to your cellphone, but you do not have to register on your cellphone. Just type in the code that was sent to your phone. If you don't have a cell phone, under the space where you are to put your phone number it says "send email instead". Then they will send you an email with a code. This might take a little longer.
- If you have any questions, please contact one of our receptionists during business hours by calling 815-455-5400
