Cleveland Clinic Reply

Thank you for this feedback. It is how we all learn and patients teach me all the time. I have thought a lot about my approach with patients. On one hand, I want to make sure they feel informed about whats going on and the options available to them, so we can make the best decisions for next steps together. On the other hand, I want to meet people where they are and not overwhelm them. In my line of work, things can be scary for patients despite my best efforts. What I want every patient and potential patient to know is that I will be honest about what's going on and am on this journey with you. If its helpful for you to re-connect to address any concerns, please reach out to my office at 954-659-5840 and we can schedule some time together.

Oh my gosh where do I start! I cannot find enough words to describe Dr. Nagarajan, he is so caring and concerned about me as a person/patient first, he is an exceptional Doctor. I love that he goes above and beyond the scope of relaying info making sure I understand what my care/healing process looks like. He also allows me to make what I feel is the best choice of action and then if it's not the right decision "according" to the CDC he shows it to me, explains it and therefore I have the option to continue with my choice or, go the medical route. I love that about him. And, he is also very patient with me and he's never in a rush and that you don't find in Dr's now day's, they're all in a rush to get to the next patient. Thank you guy's for choosing quality staff.

I find all my interactions with Dr Nagarajan too be very inspiring. His bedside manner when I first saw him for the first time I had cancer had a tremendous effect on my life. At that point, I did not want any treatment for cancer as I just thought I had had enough trouble in my life that I didn't care if I died from this cancer. He told me a story about something that had happened in his life and that had an effect on me and gave me a hope that maybe it would be better to live than die! we agreed that 3-5 radiation treatments might not be so hard and stressful to go through. He gave me the desire to live again and since then, my life, my whole self and inner strength has been so charged with love and hope, that I will never forget his physical and emotional healing miracle he did in my life!!
