Everyone made me feel Welcome. Each person kept me informed of what was going. This is very important for each patients needs. We come in being so nervous, we need a smile and reinsurance of what going on. As well, answering any questions. Thank so much! Thank you!.....Dr. Marco Paez

Mi experiencia en la unidad de gastroenterología de Dr. Marco Páez fue muy agradable, ya que mis temores fueron muy diferentes a lo que esperaba, solo recibí atenciones por todo el personal con el que tuve contacto desde mi llegada en recepción, enfermeras, y doctores, así como la explicación del lo encontrado en el procedimiento que me realizaron, con este tipo atenciones quitaron muchos de los temores que tenía en mi cabeza, le estoy muy agradecido al Dr Páez y todo su equipo de colaboradores. Gracias

As my 1st time patient to undergo colonoscopy, I feel calm that day bcoz my Anesthesiologist she is very nice, the tall nurse who assisted me she's nice too and make you comfortable but sad to say the one younger assistant there a little bit rude, not smiling and make u in a hurry like you have a party girl?!😅😁🤭🧐Dr Marco did a great job, I passed out when I woke up it's done!!! YOU feel u have a good nap😅🙏👌 Good job and thanks God even though I have 2 polyps it's benign no need to worry! Keep up the good job🙏💯👌
