I use to teach trumpet lessons (Buddy Rodgers Music, North College Hills) when I was a starving college student trying to make extra cash as a musician. That and my band paid my way through college. And I still perform today, 50 years later as a musician (and a card carrying AFM member to boot) but no longer teach trumpet. I now teach however, in my other chosen profession, health care. Wish I had the wisdom way back then, 50 years ago, that I have now as I would have been much more accomplished as a trumpet teacher.
Fast forward to today. I address my patients by putting them into the prospective that you (the patient) are my boss, and I am only your spiritual advisor. I then let them know it is my role in our relationship to provide them with the relevant clinical expertise centering around their needs, and then provide them several options. They choose the option they want (or sometimes even create an option I did not even bring forward to them). I will go with whatever direction they provide (as long as it does not harm them - "first do no harm"), but then follow them up shortly to take inventory as to where they are and if their goals are being achieved. If so, continue in the same direction, if not, try one of the other methods that I provided based on well documented evidence.
Key is, you got to get their trust to move forward and if you hear and work with each other, a successful outcome will be achieved.
