Just wanted to say what an excellent experience I had at Kaiser North Capitol, in D.C. on yesterday for a colonoscopy. It was the best experience I ever had for such a procedure and the staff was kind, considerate and helpful and more importantly, I felt no discomfort. So, hats off and a bow of appreciate to Dr. Defonseka and her Colonoscopy staff and Capitol Hill.

Tackled a difficult, chronic problem and followed up diligently. Went above and beyond investigating any possibly related health problems, such as anemia, and kept me completely informed.

Dr De Fonseka is without a doubt over the top the best doctor ever. I have met several gastroenterologists and she surpasses them all. She is THE ONE doctor who actually listens to me, and the best part is her personality. I wish her the best of luck in her career.

Dr deFonseka is a real patient advocate and an excellent doctor. When other doctors were pressuring me to get a colonoscopy, Dr deFonseka walked me through the pluses and minuses and helped me to make the right decision for me. I'll be happy to see her again.
