It sounds like Charlie doesn't regard you as the giver of all good things in his life. You need to get him to realize there is no question about giving you something when you ask for it. You don't need a behaviorist at this point if you are willing to enroll him in a obedience class and teach him you are the decision maker.

Obedience classes are essential to establish a bond between the two of you, with you being the one to make all decisions. Training with his kibble would be valuable since it seems to be goodies he regards as his favorite possessions. Make him work for each bite of food he gets. Sit = kibble. Down = kibble. Give = Kibble. Start out teaching "give" or "release" by using something he is not real possessive of. Perhaps a toy. If he refuses to do what you ask, kibble disappears until next meal time when you try again. Eventually, he will understand he needs to listen to you to get his kibble. To spark the training faster, you can try something really irresistable to him. Chicken, hot dogs, cheese, whatever it takes. Ultimately though you want to use his regular kibble.
