With me he seems to have started trusting, as long as I remain relaxed and calm.

Started with touching his head with one hand speaking easily, giving a treat. Progressed to 2 hands. Then with something in one hand giving a treat everytime I pulled my hand back.

When I got him to where I could have something in my hand, and pet him without stress behavior I moved to a hair brush and brushing him as a reward. 

While brushing I will pet his head and scratch his ears with the other.  So far so good with me,

Have slowly progressed to where I can wrap my arms around him, and was actually able to pick him up last night twice with no stress behavior on his part.

Now I need to have my wife start working with him,
