    David Niumatalolo was very professional. Sounds silly but it was like he could feel what you felt at the moment and he would reach. I was nervous, so Mr. Niumatalolo took his time to explain the procedure. He listened, and gave the best detailed response a doctor could to their patient. I became more confident and I truly felt comfortable for the first time in a long time at a doctor's appointment. MR. NIUMATALOLO, is awesome! Thank you, for the experience. It was a pleasure meeting you
