in Newport Beach, CA |
very nice procedure with Dr chaurasia and staff. everyone was super friendly and I was made comfortable before and after the procedure.
in Trabuco Canyon, CA |
Dr. Chaurasia was kind & explained things to me when I was in the hospital. Then i visited him for a follow-up appointment. I was able to schedule my colonoscopy before the end of the year. I had some abdominal pain after the procedure, & I was able to talk directly to the nurse & she in turn to the Dr. I was reassured about what was happening & what to do. When the biopsy report came back, Dr. Chaurasia called me himself with the results. I really appreciate that.
in Mission Viejo |
I had an excellent experience. Dr. Chaurasia's staff was very comforting and put me at ease. I recommend Dr. Chaurasia with complete confidence.
Professional staff that explains details of your specific procedure. Dr Chaurasia takes time to explain procedure results and answer any questions you might have. Always a follow up on any lab results that are usually available within a week.
in Laguna Niguel, CA |
Dr. Chaurasia provided a thorough explanation of my colonoscopy procedure during the initial consult. He allowed ample time to answer any questions/concerns in advance of the scheduled procedure. On the day of the procedure, he again offered me an opportunity to answer any questions I may have had since our original consult. His staff was both professional and sensitive to my every need and Dr. Chaurasia was the consummate professional both before, during and after the procedure.

DR. Chaurasia and his staff are professional yet friendly and warm. They make you feel important, cared for, and safe. All of the steps for my colonoscopy were met with surety, instilling confidence for me in their work. Hiccups along the way (my insurance didn't have my coverage updated at the first appointment) were handled easily and rescheduling was not a problem. The procedure was frightening to me, but they made it simple, easy and not a bit scary. Even though I did it on Halloween!

in Dana Point, CA |
I appreciated that in January 2012, after performing a colonoscopy and before I went home, Dr. Chaurasia called my wife and I into his office and stated that I had colon cancer. Even though this was before the biopsy results he wanted to let us know so we could take immediate action. His statement was based on years of experience. He did not want us to wait because time was of the essence. (I was diagnosed level IIIC.) He also offered advice on what to do next. Doing this was helpful.

I believe this was my third colonoscopy with Dr. Chaurasia and as before I was made to feel very comfortable.

The doctor & office staff were exceptionally kind & personable. The procedure was painless and the care they offered before, during and after was incredible. Grateful!
in Huntington Beach, CA |
Excellent pre-op visit, but on date of actual procedure they were running very late on seeing patients. Had to wait almost two anxious hours before it was my turn, although I was originally told it would be approximately 45 minutes. First ever colonoscopy and was a bit nervous to say the least. When I expressed to the doctor my uneasiness he replied, Well, there's a first time for everything. Not the calming answer I was hoping for. Procedure was also a bit more painful than I hoped for
in Coto de Caza, CA |
Excellent professionalism and expertise.
in Aliso Viejo, CA |
Thorough explanations of all details and a caring staff made an unpleasant procedure as pleasant as possible!
