It was a pleasant experience from start to finish. The desk person was very professional and friendly as well as all the ones after her. Bri was very competent during the admittance and helpful in getting me ready for the procedure. Hailey was a friendly face to see afterwards and her professionalism made me feel positive about the procedure. Dr. Lacey was a calming presence before and after the procedure. I would gladly refer others to your center.
