My mother taught me it's important to be true to who you are. I think there are some exceptions.
I want to thank you for diagnosing my daughter and commencing with treatment which helped her finally begin to regain her health. For that I am genuinely and deeply grateful. I tolerated your arrogance because it was backed up by knowledge. However, your extreme disrespect for the patient and her parents, unwillingness to discuss pros and cons of alternatives in care, manipulation, threats, and generally bullying behavior are unlike anything I have ever encountered from any medical professional and as you well know we have seen more than our fair share of doctors.
It is without the slightest trace of sadness that I bid you adieu. First, allow me to dedicate a song to you.
