14 years and counting. The best MD I've had in many respects, I trust his clinical judgment fully.

I just LOVE Dr. Regueiro !! I have been seeing him for many years and I travel from Ohio to see him. He is very thorough and very nice and very easy to talk to. All these things are very important to me as a patient..

Dr. Riguerio should be a model for all care givers. He is a leader in the field of research, he provides excellent bedside manner and makes decisions based on the best outcome as opposed to reacting just to a patient's reactionary wants. Can't speak highly enough about him.

always a great experience and assuring

Dr Reguerrio is very patient and thorough. The care and compassion that his nurses, Beth and Joann is a reflection of this. Numerous phone conversations, emails over the past few months have always been returned promptly. Joann went out of her way to meet me personally. That meant so much to me.

It was a good experience. Only there for a check up at the time so no care was really needed concerning pain or sickness.

As always, an excellent visit and excellent care
