More Testimonials From Our Patients

My whole experience with you, and the very professional staff at Orange County CyberKnife and Radiation Oncology Center, has been exemplary. Not only did I feel the complete medical competence and commitment of each staff member, which gave me total confidence in the process, I also received the added benefit of humanity, given in the form of smiling greetings, warm inquiries as to my state of self, and personal interest in my progress. Truly, after seven weeks of five-day per week treatments, I was sad to say goodbye.

I never witnessed anything other than sunny attitudes by everyone in the office, and the obvious aim of getting me in, treated, and out seamlessly and efficiently, was a real blessing. I literally waited a few minutes only three or four times in thirty-five treatments, even when I arrived early for my appointment. It was amazing. Your personal care of my entire radiation process was also unparalleled. Your instructions were absolutely clear, you allowed me to ask questions as long as I needed each time we met, you respectfully used language I could understand, you thoroughly prepared me for the process, and handled each step with such deep consideration for my health – both physical and emotional.

I can’t thank you and your staff at Orange County CyberKnife and Radiation Oncology Center enough for your great work. Truly, gratefully yours,
