Guten Tag Jonathan! Ich heiße Alex. Ich bin aus Pennsylvania. Schön dir zu treffen!

When you're saying that you live somewhere, use the word "wohnen" instead of "leben." Good conjugation though! While the word wohnen means that you live or reside somewhere, the word leben means 'to be alive'. 

My German teacher in high school would call this Ganglish, haha. It's when we translate from English to German word for word. 

Also, aus means 'out of' or 'from', von also means 'from', but isn't used with a geographic location.

Take care!
