Dr. Chaurasia and his staff are very professional. I had a very good experience and would offer the highest rating to him and his staff. Matt Baer
in Laguna Hills, CA |
Dr. Chaurasia and his staff were friendly, very efficient and I received a call within two days with results. I would highly recommend to family and friends.
San Clemente, CA |
Dr. Chaurasia barely spent anytime at all with me, and actually cut me off multiple times during my first (and final) visit. It definitely felt like he wanted to get me in and out quickly, as they were behind schedule. He even asked if I think I have cancer when I already have a diagnosis and just need help with it. Not a pleasant experience when someone just clearly doesn't want to work with you.
I hope that we may be able to win your favor again, as your experience is not at all indicative of our patient care standards. Thank you for your comments.

Could have not asked for a better outcome to this rather uncomfortable 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 wonderful! They were awesome on the initial visit when I needed to get in and out quickly due to scheduling issues with my son.

I highly recommend Dr. Chaurasia!!

in Corona, CA |
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!

I have seen Dr. Chaurasia three times over the years, including very recently for a colonoscopy. He is terrific as are all the members of his staff. They all made me feel as comfortable as possible. I would not hesitate to recommend him and his office.
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.
