Hi Italki friends.

My name is Oscar, I am Radiologist an live in Bogotá (Colombia). My main interest is learn English and need a lot of friends with whom I can chat and practice the language. [Alternatively, you could write "...friends I can chat and practice the language with".]
In my daily activity work in the Hospital I realize [this is not incorrect, but is awkward in English.  Consider "I perform procedures..."]  diagnositic and interventional procedures image guided.
I am married and with my wife we ​​expect a baby.

I hope to get corrections.

Thanks
