What ages do you teach? 

From 6 to infinity!

Do I need a piano? 

I suggest you start with a good quality digital piano with sustain pedal.  The day will come when you realize that there is nothing like a high quality acoustic piano.

How much should my child practice?  

Everyday, between 30 minutes to 2 hours.  It really depends on the age and what goals have been set.

Do you teach students to play with chords or by ear? 

Not directly.  Eventually chords are learned and playing by ear is discovered.  A curriculum based on chords does not fully develop the student’s ability.  Playing by ear is a wonderful by- product of a strong technical and music theory core.  I enjoy both paths and gladly share my knowledge with students.
