Patient Care Philosophy

I believe in the importance of amplifying the voice the patient and practicing shared decision-making in determining the next best appropriate plan of action. I believe it is important to maintain the patient's health throughout treatment, keep their energy level as high as possible, and maintain a positive outlook on life.
