Dr. Mack Roach III is a radiation oncologist and an internationally renowned expert on treating and managing prostate cancer.

Roach's research investigates new techniques for treating prostate cancer, such as 3-D conformal radiation therapy, in which the beam is matched to the tumor's shape, sparing healthy tissue, and intensity modulated radiotherapy (IMRT), in which radioactive particles are inserted into the prostate gland, beside the cancer. He also studies such established treatments as brachytherapy. He chaired an important clinical trial comparing strategies for locally advanced prostate cancer.

Roach earned his medical degree at Stanford University School of Medicine.

A global authority on treatment planning for prostate cancer, Roach served as senior author for the American College of Radiology's guidelines on the subject. He is a member of several professional organizations, including the American Society of Clinical Oncology, American Society for Therapeutic Radiology and Oncology, Radiation Therapy Oncology Group, National Cancer Institute's IMRT Working Group and American Joint Commission for Cancer Staging.

About our process
Mar 27, 2025
Met with new resident who asked appropriate questions. Then attending stepped in in his usual No-nonsense way to get to the point that follow up can be done as needed without regularly scheduled visits. He offered direct email contact if my preference. The visit was quick and efficient.

Very poor follow up.Didn't seem engaged with my treatment and care.Seemed preoccupied with other issues.Didn't seem to care too much about my condition and treatment.

I am fortunate to have Dr Roach as my oncologist and feel he has a genuine concern for my well being. My complaint has more to do with they system that is tasked with analyzing data, processing it and getting it back to the patient in a timely manner.

I came to Dr Roach to get a 2nd opinion and was so impressed with the positive approach taken by both him and Anthony that going forward I would prefer being treated by him for my health care concerning my prostate cancer.

Dr. Roach showed us the latest images of the tumor and the heart distance apart confirming that Radiation is indeed the best option for the tumor

Dr Roach is quite concise and doesn't say much. So not disappointed. As this was my second visit with him in 3 years, he didn't review risks or safety measures or time of radiation except to say less than 5 days.

Dr roach and dr real we're excellent!
Oct 24, 2023
It wasn't a bad experience, but I kept getting the feeling that he felt annoyed by my questions, and he seemed a little arrogant in his responses. I did not get a warm and fuzzy feeling from him.

Had no issues. Very easy to talk to.

Care provider knew nothing about me. It was clear he never looked at my chart even though the appointment was made over a month ago. Showed little to no emphathy or concern.

I'm in very good hands.

The doctor obviously wanted to get the meeting over with as soon as possible.
Aug 22, 2023
Overall, extremely happy with Dr. Roach. He was well informed about my records, and he talked with me, and not at me, taking the time to respond to my questions and also displaying other medical information and articles relevant to my case.

Overall a good experience about a bad subject.

Informative and professional; made it easy to understand.

Dr. Roach is very knowledgeable and is held in high regard by people in the industry. But, I found him somewhat arrogant and was rushed for time and cut my meeting short, when I had more questions. He suggested I contact him through MyChart, if I had more questions. As I mentioned earlier, I find that method of communication inadequate.

Dr Roche is a superb Doctor on all counts!!!
Jul 12, 2023
Very good
Jul 07, 2023
They did not allow very much for me to get my words in edgewise - the whole discussion last about 4-5 minutes
Jul 06, 2023
Appointment seemed rushed. Primarily Dr. Roach explained his proposed treatment with scant time for indepth questions. This may be due to the second opinion aspect of the appointment.
