Well, I don't really know of any clinics per-say, unless you are fortunate enough to watch Ty fish a hole
I would suggest either head toward local waters and learn "the hard way" or hire a guide capable of taking all 3 of you. You will all learn some very valuable lessons. You may even discover that they will enjoy different ways of fishing (ie drift gear, spinners, or floats) then you can get them gear (rods & reels) to fit what they like. I dunno, just a couple of suggestions!
When my dad & I "discovered" steelheading we both spent a lot of time learning...I didn't pick up things like he did, but I was only 12. He caught a few steelhead that first year while I only watched. I still really enjoyed spending those cold, damp, fishless days doing something cool with my dad.
Good Luck! This kind of behavior needs to be encouraged!
