The attention from the moment we arrived was excellent; they were very attentive and kind. The doctor explained the entire procedure to me. The nurse was equally helpful and explained exactly how I should take all the medication on the day of my procedure. I was very happy and satisfied with my appointment. Thank you.

The service was very good, and I liked the doctor's attention; the only thing is that they don't have earlier appointments available, and that's the only thing I didn't like because I urgently need my mom to have the endoscopy.

The care was excellent, truly outstanding. From beginning to end, the nurse treated me with excellence, guiding me completely through everything as I had planned. Dr. Pimienta explained everything I needed to know, answered all my questions, and explained everything I had to do for the upcoming procedure. I am very grateful. Excellent work at that office. I would gladly recommend Dr. Pimienta in the future. Thank you.

I think communication could be improved with getting, making plans for colonoscopy. I was not given the full information on my prep. I was supposed to have a two-day prep, but I did not have any knowledge about that until two days before my colonoscopy. I wouldn't have been able to accomplish that. So I think communication should be a little bit better and taken a little bit more time to make sure that the communication is clear. That's it. Thank you.
