Dr. Osman has been my 84 year old mom’s hematologist for over 4 months. He is one of the most caring, kind and intelligent, thorough doctors I ever worked with. My mom was a tough case and as a daughter I asked many tough questions. Dr Osman was always there to give his professional opinions and a sound treatment plan. He even personally spoke to mom’s nursing home staff to ensure proper care for my mom. My mom is getting better, thanks to Dr Osman for getting her off hospice. I was skeptical initially because he was new to Texas Oncology. Now, I want him to see my son as well!
