Cudahy KC has them periodically.
There are classes to prepare your dog for a TDI test, it's the CGC class, but they only test for CGC at the end of the class. You should be able to Google "TDI test near me" and find a test to complete somewhere after you take the class, but I highly recommend taking a class first so you know what to expect. TDI tests usually aren't easy to find so you want to make sure you are fully prepared :)
