Webcam singing lessons with KTVA coaches

Has anyone taken lessons with the KTVA coaches? How did it go? Did your training with them help your progress? I'm looking into starting lessons with a KTVA coach on the website and was curious if anyone else has worked with them.
Thanks!
Thanks!

I've taken 3 lessons with Ken and 3 lessons with Sara Loera. All in person, I may add.
I'm glad I took every lesson. I spaced them out 6mo apart (sometimes longer).
I saw the lessons as checkpoints to assess my current skill level, make adjustments on technique and accelerate me to the next stage.
After doing Voume 1 for maybe 6 mo I went to Ken and he immediately corrected several techniques I was doing wrong the whole time.
After doing Volume 2 I went back to Ken and he mentioned significant improvement and helped me to start singing songs better.
After doing Volume 3 I went to Sara since she's within driving distance and she's been great for helping fine tune things!
Let me know if you have any specific questions.
