This review pertains to the performance of Harold, nurse for Tracy Castaldo, P.A.. Recently my insurance company required a pre-authorization (on something of a personal nature). I dreaded hearing that word, “pre-authorization”, because in the past getting something pre-authorized almost ALWAYS took a lot longer than it should have and was often very frustrating. But, thanks to Harold my latest pre-authorization was taken care of quickly and painlessly! Within 30 minutes of first notifying Harold that one was required, he called me back and said everything was taken care of. What a pleasant surprise!! In addition, Harold has always been courteous, respectful, caring AND he returns your phone calls!! I am glad Tracy Castaldo has a nurse who shares the same impressive traits she has; traits that set her apart!
