Hola spanglishgirl, if you have Osde Health Insurance I can recommend Dra. Adriana Vilariño, she is good english speaker (I know a foreign woman in BA who say she is a good Gynec)
Av. Santa Fe 3069 2° "B" - Recoleta
Dra. Liliana Rossi has been my only gynecologist in BA for nine years. Until I learned the langugage, we conversed in English. Speak slowly. She attends OSDE patients and may still be charging only 50 pesos for a consultation. I referred TangoCherie to her, one of those who recommended her. Call for an appointment (turno) with her secretary. Office hours are Mon 13,30-20, Wed 10-13, 14-20, Fri 13-18 Tel 4901 2475 She is a doctor who listens to her patients. She's better than the gynecologist I had in Chicago.
May I ask what her office and examining room was like? I've been to a few, even through Swiss Medical and thought the rooms were terrible with this little "gown" hanging up to wear that did not even look clean. Horrors! I've also found them not to be very thorough. Thanks!
