Dr. Sergio Sierra-Dupont FRCSC, O.R.L.

Un docteur qui a du coeur un grand merci.

I have seen couple of ENT's in Montreal. He is very exceptional, he explains in details what my problem is and the two option for the treatment. He cares a lot about his patient. Live long Dr. Sergio

He knows exactly what he's doing. Just remember to ask about potential side effects, and maybe a follow-up.

Excellent chirurgien !

Super Dr 100% lo recomiendo soy paciente DEL Dr Sierra -Dupont desde 1995 el me opero Y estoy feliz Dios me lo Bendiga siempre

A friend suggested dr. Sierra Dupont because he has been his patient for over 20 years, so I gave him a shot after reading positive reviews. I have to say, he I wasn't in the least disappointed! Dr. Sierra is very calm natured and very patient. He is one of those rare doctors who takes the time to explain everything, answer questions and actually listens to the patient. It showed he has years of expertise. He prescribed me an oil for my nasal passage to keep it lubricated and explained how to use it as well. Excellent dr who i highly recommend and will continue to see. His secretary was also very sweet. The only thing that is a bit difficult, is the parking but i promise you, its worth it nonetheless! I ended up finding indoor parking on a parallel street (on mackay).

ho yey super good!
