Both my siblings went to Lewis & Clark for their MATs, and both are now teaching in Oregon. I would suggest that since your goal is so specific, contact the programs you are looking at to find out a) what is the geographic representation of where their alumni are now, b ) how strong is the alumni network in the PNW, and c) how many of their alumni go on for higher degrees later on. As you point out, L&C has a great relationship with school districts in the area and are well regarded in the PNW, so really it's finding out what that means if you were coming from another school...
Good luck!
