She was great. Figured out what was wrong after we had spent 1.5 years with another practice who couldn't figure it out!

Dr. Riera was wonderful. She spent the majority of the time we were at the office with us, and she explained everything well.

Again we were very please with our doctor. She explained everything to me and my son. And that made him more at ease. I would highly recommend her to anyone that was in need of a GI doctor
