I have been teaching on and off in between and during engagements for the past 30 + years. Those students were satisfying, in that we would do a whirlwind of lessons in a few days, or they would come stay with me where I was singing, and we’d hash through as much technique as they could muster in the time we had.  I’d throw a lot of ideas at them to work on when they got home, give them tools to know HOW to do that work, and then see what stuck.  I am happy I have been able to help countless singers to reach their goals who are now…
