I have taught students from elementary school to college majors as well as retired CEO beginners and board-certified vascular surgeon amateurs.  As each individual presents different requirements, I don't follow a formula ever.  But some of the issues that recur often with many of my students are:

Sound Production
Physics and Feeling
Physical Comfort
Mental Game
Theoretical Grounding
Historical Relevance
What Does Cello Do for My Life
How Can Cello Get Me Money For School?
Practicing Sucks: Do It Better

Having just moved to Silicon Valley, I have multiple openings for the right students.  Contact me to set up a preliminary meeting.
