Most thorough doctor I have ever been to. He goes over everything and has a exceptional bedside manner. He checks all things associated with my condition and is very knowledgeable about disease. I would refer all my family and friends, acquaintances to him. I believe he is one of the best in his practice and keeps himself updated with all new treatments. His nurse is very nice, polite and friendly and helps with any and all questions. Front office staff is also friendly and help full. Lonestar Oncology and Dr. Sabbagh are both wonderful I am so happy I changed doctors to have them in my corner! I’m not going to mention the other Oncology facility I used previously which didn’t catch my mothers cancer in time while she was under there full time care but I wish she would have had Dr. Sabbagh she could still be here with me! Thanks for all Lonestar Oncology does and the people it employees!

Dr Sabbagh, Dr Shimkis and the entire nursing and lab staff have been so incredibly thorough, helpful, positive and compassionate in the care for my Mother. While a Cancer journey is unexplainably difficult on the patient and family, having a care provider you can trust with your life is priceless. Dr Sabbagh has been so involved, prompt, and efficient in her care. The office is also exceptionally clean and beautifully appointed. On behalf of our entire family, he will forever be in our hearts and prayers with the utmost gratitude and respect. If you need care for yourself or your loved one during cancer treatment and/or diagnosis- don’t hesitate to reach out to this Dr. to help!
