  • "Dr. Asmar is not only a one of kind doctor, but he's truly a one of a kind human being. When my grandma became sick, it was Dr. Asmar who *quite literally* saved her life. It's because of him that she is still with us. He's extremely thorough, communicative, thoughtful, empathetic, and gracious. When I personally had an issue, I went to a local hematologist who gave me terrible advice. My mom suggested I talk to Dr. Asmar (since he saved my grandma) and he did not hesitate to help me, despite being in a different state. He guided me through the treatment plan and made sure I was well taken care of, even following up proactively on my status. My mom, who is his primary contact with all-things related to my grandma, is truly in awe of the type of doctor Dr. Asmar is. If there were only more like him ... Dr. Asmar if you read this: THANK YOU."
