I used to work in the office engineering comercial doors for Anozira Door Systems (that's Arizona spelled backward), before I moved down here... also did comercial and airplane hanger doors with my friend who owned Evans Dock and Door... we did the Collier Center across from the park where the D'backs play baseball... we made the second story of that high rise open up using airplane hanger doors instead of a wall... I know a little bit about garage doors...
I used a guy named Andres, who is a friend of a friend. His # is 638 113 0328, once for a door that slipped off the track, once to get the opening motor replaced.
Both times he did fast, inexpensive work, and speaks English
