Deffenbaugh is totally professional. Mark is an excellent teacher with many years of experience. I have been taking lessons since childhood and have never had a better teacher.

Reviews ​"I interviewed pretty much every music teacher in Alexandria before deciding to go with Mark. There are two types of music teachers I've found - amateur musicians who play guitar in their own band and think they can teach any musical instrument, and professional music teachers who don't have a lot of musical authority. "Mark is a musical authority - a professional musician, with solid credentials, and he's an excellent teacher. I really feel like I'm training from a master and not just from an old-fashioned teacher who's stepping me through an instruction routine." " He's been able to bring me up to speed on piano very quickly with no pressure. He explains musical techniques and concepts so that they're clearly understood and easy to learn."
