  • "I could NEVER find a kinder hematologist! Dr. Hendler is incredible!! I happened to ask him about a stomach issue I had. Completely out of the realm of his specialty. He ordered a sonogram of my abdomen. As if that wasn’t enough. In addition. He’ll ask me. “Have you had a mammogram or colonoscopy done?” ☑️ I’m thinking to myself. 🤔. He a hematologist. Why is he asking me? Doctor Hendler is AMAZING!! You should feel blessed if he has room in his schedule to take you on as a new patient. I sound partial. I am. I’ve had serious problems with my kidneys. Hence, I see him often. It affects my body from producing the appropriate amount of hemoglobin. Dr. Hendler is on TOP of everything!!!!"
