recommendation for seattle area base diagnostic?

I've owned my truck since March or April and haven't driven it much until lately when moving from boat back up on land. I have space to do some repairs and catch up on deferred maintenance but I'd really like to have someone who knows these trucks forwards and backwards who can spend an hour or two and giving me a list of things to get to work on.

Anyone know of a good powerstroke expert in the Seattle area?

Thanks.
