Nick Petrels is a doctor in Montreal. He works 60 hours a week. He takes care of 159 patients a week in the hospital and at his office. He’s been a doctor for ten years.

Dr. Petrels gives his patients good medical advice. But he doesn’t just tell his patients what to do. He also sings to them on television! Dr. Petrels has his own TV show. The show is in Italian, English and French. The doctor starts the show with a song and then gives medical advice. He explains a medical problem or disease in simple language. After that, he sings another song.

Dr. Petrels produces and performs in his own show every week. The program is very popular with his patients and with people who enjoy his singing. His dream is to perform in Las Vegas.

All my problems are gone when I sing.” But when Dr. Petrels was young, his father didn’t want him to be a singer, so he went to medical school.
