I saw Dr. Reguiero because my previous physician suspended her clinic time. Dr. Reguiero was very prepared and knew my care plan and health needs as if he was my normal physician. Although I waited a significant amount of time to see him, he was very apologetic and spent enough time with me to answer my questions and discuss my concerns.
