All payments are made by credit card or Apple Pay through our website and iPhone app - you never need to have cash on hand (though you are welcome to tip the therapist in cash or leave it with the Maitre'D!). You can even charge any gratuity you would like to leave to your payment method on file. After you finish your appointment, you will receive an email and text message asking you to rate and review your Therapist. At that time, you will be able to add a tip as well.
