All purchases are banked and scheduled at your convenience. Specific appointment times may be subject to availability. Purchases do not expire, and remain as a credit on your account, until redeemed upon service. All services are subject to initial consultation by the physician, which includes a medical history and examination. In the event it is determined by the physician that you are not an appropriate candidate for treatment, all unredeemable monies will be happily refunded. In the event of unforeseen circumstances, monies for unused services will also be fully refunded.
