About me

Philosophy of Care 

The following two quotes by Sir William Osler, 19th century Canadian physician, sum up my Philosophy of Care: “Listen to your patient, he is telling you the diagnosis.”

“Care more for the individual patient than for the special features of the disease. Put yourself in his place. The kindly word, the cheerful greeting, the sympathetic look – these the patient understands.”

    Very approachable and warm

  • Jun 23, 2021

    Dr Hellerstein is extremely patient with my very anxious daughter. She was respectful of my daughter. She was able to modify the exam some to make my daughter more comfortable. I am so appreciative of doctors etc who understand that this was difficult for my child and didn't become frustrated with us.
