His position likely prevents him from asking you out. He has a professional position to protect and anything he does might lead to him being accused of ‘s***** harassment’.
You can always have lunch with him at the hospital cafeteria and talk with him to find out more. Is he married? Engaged?
Go slowly, act like a friend and not a lover and see how it goes.
