I want to thank (two names removed) for having such an excellent oncologist. He has been very helpful, dedicated the necessary time to me, and explained the results very well.

May 23, 2025
The only reason I didn't rate higher on the survey was because it was my first time with this oncologist. I think the more I see him and get more comfortable with him, I think all of my responses will be 4s and 10s. But for now, it's my first time meeting him. I'm still getting comfortable with him and just wanted to note that. Thank you.
May 19, 2025
I was real happy with the new doctor. I had a different doctor, the other doctor quit. And I was real happy that he listened to all my information and that he gave me good information. So I was quite pleased with him. Thank you.

I am so sad Dr (name removed) left. This guy is pretty good, though. He took ownership of my abnormal lab results and scheduled assessments right away.

Yes, good evening. Dr. Cheng is my favorite doctor now at PIH. I want to thank him for when I first went in there, my prostate cancer score was very high. With his treatment and his knowledge, my PHS score now is down to 0.21. I want to praise him. He's the best doctor I've had at PIH in the five years I've been with you. Thank you very much, Mr. Brian Cheng. Have a good evening. I'll see you soon. Bye for now.

Dr. Cheng is a very, very knowledgeable oncologist. He provided very, very good detail on my treatment and also the plan moving forward. very professional and again, very detailed to every step moving forward.

I saw Dr Brian Cheng for him to give me my blood test results and recommendation for treatment if needed. Dr Cheng was very courteous and was happy that I did not have anemia. I will have blood tests and a followup visit in 4 months to see if my anemia has not returned. My 4 months appointments were made. He was happy with my results. I was very happy with them. All questions were answered. I had a very good office visit. Thank you Dr. Cheng.

Dr Cheng was very nice. He was informed of my history even though it was the first time I had seen him. He listened to my updates and filled out the request for the next CT Scan and Colonoscopy. He wants me to be able to get well enough to not have so many appointments, which I appreciate. The nurses and office staff are all so nice and care about how I am feeling. It is so nice to be treated so well.
