We worked with an ST who also contracted with Lab and it was not worth the money. I assumed Lab meant it would be top notch. That has a few years ago though so no idea if she still is affiliated with Lab.

To the person who said not to get hung up on certification and training, you couldn't be more wrong. We chose a tutor from the Lab list who was "trained" in OG methods. My kid made no progress until we switched to a certified OG tutor. It was a world of difference. We worked with Dr. Walter Dunson. He was wonderful.
