Exactly how we used to 'tweak' a door to fit when I ran an automotive body shop. That is if 'tweaking' was the way to fix, otherwise it was pull the door and shim the hinges. Tweaking was much faster and cost less too.

If you left it at a shop, they would have you leave the area and then they would insert a one foot long 4" x 4" near the middle or upper portion of the door, close it and push on the bottom of the door, tweaking the frame back into compliance.
Obviously, this is done gently, making sire not to damage the door.
