I have taken piano lessons on and off for over 25 years from 10 different teachers.  Until meeting Steve, I could not play a thing from memory, but could read music reasonably well.  Having finished only my second year of lessons with Steve, I can now play over 15 different, very difficult jazz, pop, and improvisational songs from memory alone, and have recorded them on a CD.  I know from experience that the difference is Steve.  Steve is a master in his field, and you would be hard pressed to find anyone even close to his caliber.  My name is Judy.
