Always a great experience with Staff at the front desk and they are always helpful with explaining and giving a breakdown of what you're getting done and how much. I've been going for more than 5 years and now even my son is a patient and he loves it. Thank you Jorge Carlos DA and RDH Shaun Reilly for taking care of me and leaving me with a beautiful smile. Highly recommend.
