Dr Berstein is a very devoted and caring man. Even though he is a children's oncologist, he is one of the only hemotologists in the area that has a full understanding of factor 5 lieden deficiency and factor 2 proficiency. It is a rare bleeding disorder and often when I appear at the ER and find a doctor that needs to be quickly educated on it so I don't die from blood lose or from receiving the wrong type of blood products, well, they get offended and ask me when I went to medical school. I can call Dr. B any time day or night and get his help. He is always ready to be there for his patients. I am by far not a child but he still takes good care of me and I even get a sucker if I'm a good girl at my visit! :}
