Patient Reviews

“Doctor Gajanayaka and the Staff at DNA provide personalized care which is top class!”

“Funny, compassionate, professional in giving all info needed to me in regards to test results & all I need to know, especially how we work together from diagnosis & going forward. He makes visit very comfortable with his patients. I recommend Dr G for anyone.”

“Dr. G is the absolute best and I don’t say that about any of my doctors. He has a genuine care and concern for his patients that you will be hard pressed to find anywhere else. What i love about him and which is also the reason I have decided to stay with him is because he doesn’t put you on medicine unless you need it. He doesn’t have the pharmaceutical companies in his pockets. Your appointments will never feel rushed with Dr.G. You won’t regret having Dr.G as your nephrologist.”

“Dr. Gajanayaka, and his entire support staff, are totally professional, respectful, efficient and friendly, and make each patient feel special by providing outstanding patient care!!”

“Dr. G really talks to his patient as a true friend would. He clearly explains with a profound interest & kindness. He answers your questions & makes sure you completely understand all He tells you as His patient. I put my Faith & Trust completely with Dr. G & all His medical findings within His treatments for my Chronic Kidney Disease.”

“”Dr. G” was thorough, explained in detail my health status and set me on a plan to preventively manage and ensure my quality of life for the rest of my life. He wasn’t rushed, asked questions of me, answered my questions and I have the confidence that I have an outstanding member on my health team. The office staff were kind, friendly and demonstrated that they cared I was Dr. G’s patient. I have never been the patient, but always the doctor. I had (and will have going forward) an outstanding patient experience!”

Dr G from my very first visit & all visits that followed were very comfortable & professional. He answered all my questions so I would understand & there wasn‚Äôt a question he couldn‚Äôt, nor wouldn‚Äôt answer for me. A Great Nephrologist in my opinion. Thank You Dr G

“Dr G made me feel very comfortable and relaxed. He was very caring and took his time explaining everything to me. I feel I am in good hands with Dr G.”

Dr. G made sure I had all the time I needed to understand what my tests showed and made sure all my questions were answered. He is a very caring and considerate doctor and I feel blessed to have found him.

Very friendly, listened and I left with a positive feeling.

Dr. Gajanayaka is a knowledgeable and caring physician. I would highly recommend him to anyone needing a nephrologist.
