Mark Murphy Music. I had a music teacher (not from MMM) once say that kids dont pay attention as well if the lesson is in the home and I think there is some truth to that. I really enjoyed my time at MMM and my kid did too. Good luck!
There's a couple listed here:

Douglas at Mark Murphy music my daughter has been with him for years now very serious and a jazz musician himself
Courtney Sappington has been teaching guitar in Maplewood for over 10 years. He has tremendous experience with children and adults and is the after school guitar instructor at Newark Academy. See his website: courtneysappingtonmusic.com. He is also an outstanding guitar player and performer. Full disclosure -- he is also my husband! And father of an MMS son. You can reach him at 646 483-3413. He gives lessons in our home in Maplewood and will also travel to students' homes (for an extra charge).
My 12 year old daughter wants to take guitar lessons. She took a little piano a couple years ago but other than that no musical background. Suggestions? Instructors that will come to the house would be preferred but otherwise anywhere in MSO is fine. Thanks.
