Make text box text start at top of box, not centered vertically

It seems all my text boxes i have start the text in the center of the box vertically, then spaces it out as you type more.  is there a way to make it start at the top of the box and work down, just as if you were typing in Word or Notepad.  if someone only types a few lines, it looks kinda odd having the text in the middle of the box with all that white space above and below it.
