Testimonials

What our patients say about us

“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.”

— Skin cancer patient

“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 years. Please give him my great kudos. I wish there were more wonderful humans who are doctors — he was that amazing.”

— Patient, age 76
