June 23, 2025
Dr. Cilley is great. His patient care is not about ego, degrees, etc.. Dr. Cilley's patient care is about his patients. He asks questions, LISTENS. Seems to put himself in our position, then somehow treats patients the way he would want to be treated as a patient. It's amazing. The only way to truly understand how great Dr. Cilley is, is if actually one of Dr. Cilley's patients. Patients who score Dr. Cilley as a doctor, win the doctor lottery.

June 14, 2025
I arrived early and was seen early to my surprise. Dr. Cilley understood the importance of the issues that I came in with and was able to immediately get an infusion set up within the hour. Within 2 hours I had not only seen him but also had 2 infusions. I've been seeing him for years and would not see another hematologist.
June 7, 2025
Dr. Cilley is one of the best medical professional I have ever encountered I am a technical person so I always have a lot of questions and he very patient and always breaks things down to make sure I have a clear answer and understanding of what I need to do. I do regular follow up visits with him because I value his opinion as a medical professional
June 7, 2025
Our experience with Dr. Cilley and his staff was excellent. We were taken to the consultation room in a timely manner. The nurse (whose name I unfortunately fail to remember) was very pleasant and efficient. Dr. Cilley was also very pleasant and on this, our first visit, he had already reviewed the test results and was fully prepared to discuss my situation. He laid out succinctly the alternatives available and helped guide us to what I hope will be a satisfactory resolution of my situation.

My care provider was professional and compassionate during our first meeting. He showed genuine concern for my health, took a detailed family history, and ordered several tests to identify the cause of my concerns. His thoroughness and empathy are commendable.
