I have tried an exhauting search to find out information about Knapp College of Business in Tacoma, Washington. I was trying to get my transcript. Please help.

I easily found this address, but I don't think it's any good:
Knapp College of Business
1001 North J Street
Tacoma, WA 98403

According to this post, they went bankrupt:
Ripoff Report: Sallie Mae And Knapp Business College ripoff Tacoma Washington

But I also did find this:
ClosedSchoolsList

I have no idea what exactly that place is, but since Knapp is on that list, you may contact the wtb and ask them about how to go about getting the transcript.

Good luck!
