Dr. Rivera:

My father is Tom L. and I understand you have been treating him for a few months. My sister informed me that you are willing to continue his treatment at no charge. Words cannot begin to express how grateful we are. Your act of kindness and generosity has touched our whole family. It is very comforting to know that there are people in this world that have a kind and giving heart and you are definitely one of them. Thank you for your kindness and please know we are so very grateful. I hope to meet you next time in an in town.
