You can sign up in advance online or by using the Mindbody Connect App.

Please be aware of the following policies when reserving a
place in class:
-Reservations cannot be taken via telephone, email or messaging.
Online reservation closes 30 minutes before class.
Unless a class is marked as ‘preregistration only’,
advance registration is not required.
However, it is recommended for the busier classes.
-You must still check in at the front desk when you arrive.
-Please be signed in 10 minutes before class or your space might be given to another client on standby. Doors lock 5 minutes after the start of class.
If you need to cancel your reservation, please do so at least 60 minutes before class start time or your client account will be charged for that class – cancel online or through Mindbody Connect only. We do not offer refunds, but when canceled at least 60 minutes in advance the class will not be deducted from your pass. Drop in class purchases will still be available for use at a future date. No shows will be charged.  If you have an unlimited membership, on the third no show or late cancel you will be charged for a drop in.
Your mindfulness in this matter is greatly appreciated.
