Serenity One accepts payment in the form of cash, check, Venmo or Pay Pal after each therapy session. The price will remain the same for the session time agreed upon. If the therapy runs beyond the specified time and both the client and therapist are fine with this then the price will not change. However if the client first requested a specific amount of time for the session and then once the massage has begun they request an additional amount of time, the client and therapist will have to agree on a new price since the therapist will have to modify their schedule. More often then not most sessions will run a few minutes longer then scheduled for. If this was not requested then there is no extra charge for this and you benefit of a few extra minutes of therapy if you do not mind. Gratuity is not mandatory or expected but is always welcomed, thank you.
