One of the best doctor visits I've ever had
★★★★★ · TH · June 2025
“I rarely if ever write something like this, yet I have to express how incredibly impressed I was with Dr. Hess. I felt under no pressure to hurry and he was extremely clear, kind, thorough, professional, and probably one of the best in-person doctor visits I've ever had in my 76 year. Please give him my great kudos. I wish there were more wonderful humans who are doctors – he was that amazing.”
Exceptional care
★★★★★ · Healthgrades · Terry Lowell, Sep 2023
“We found Dr. Hess to be very helpful in explaining my diagnosis, the possible treatments and possible side effects. Dr. Hess was professional yet very caring, helpful and warm. His expertise was evident in the amount of time he spent with me and my wife. He did not rush through his explanations — he even encouraged us to get a second opinion. That's not necessary as I feel very comfortable in his care.”
Dr. Hess and staff saved the day
★★★★★ · Healthgrades · Steven Nicholson, Aug 2023
“Dr. Hess and staff turned a perceived horrible situation into a life of hope. I feel very lucky to have him and his staff lead me into unknown territory. All dialog received was respected and detailed with extreme accuracy. Dr. Hess is a master of details. Science and medicine meet at this clinic.”
Overdue review
★★★★★ · Healthgrades · Sandy Lapp, Aug 2023
“I am so thankful that Dr. Hess is my radiation oncologist. He is incredibly thorough. He explains everything with care and knowledge. If you want a doctor that will dig in to your diagnosis, medical records and prognosis and come up with the best plan possible, he is your guy. His staff is fabulous. Thank you Dr. Hess!”
Wonderful doctor and staff
★★★★★ · Healthgrades · April 2023
“Dr. Hess created a comfortable environment from the beginning. He explained test results and upcoming procedures very clearly. He really has the heart of a teacher and explained things more than once when needed. He also has an amazing and caring staff who made me feel so comfortable during radiation.”
A colleague's perspective
★★★★★ · Healthgrades · Bruce Lattyak, MD, Mar 2023
“Our community is very fortunate to have a radiation oncologist of his caliber. His breadth of knowledge and attention to detail are rivaled only by his passion and the personalized care he brings to each and every patient. The patients I refer to him uniformly sing his praises.”
Treated without scarring
★★★★★ · Skin cancer patient
“After being diagnosed with skin cancer on my nose, I was worried about scarring from surgery. The SRT treatment at CureRays was painless and effective, with no visible scarring. Dr. Hess and the entire radiation oncology team made the process so comfortable.”
