Dear Salomão,
My name is Armando and I was your son Sergio’s therapist during his last year in São Paulo, before he moved to New York. I am doing research related to Sergio’s case and I would be very grateful if you would consent to a brief talk. I will make myself available on the date and time that is most convenient for you. My email address is armandoa@xls.org and my telephone number, 999-9734.
Cordially,
Armando
