"Dr Hendler is a rare find! Not only is he an outstanding physician, he has an incredible caring bedside manner. Dr. Hendler prides himself on going the extra mile and always listens to his patients. My first experience with Dr. Hendler was when my life partner had head & neck cancer. We needed Hendler‘s expertise on board. He was always available, caring and made a very difficult situation bearable. Now I am going to Dr. Hendler for my own concerns. Looking for a second opinion on my CLL. All I can say is I would recommend Dr. Hendler to anyone!!!"
