1 /5 Ruben Guillen: My respects to all those who work for the health sector, I have been very patient with the Tristan clinic, but there are many occasions that I do not receive a no by phone, this last occasion they answered me that I have to call until Monday because today Friday 3.30 pm they already closed. But if you already picked up the phone, why is it hard for you to book me and set an appointment for my son? very poor service to their patients, they take advantage of the fact that there are few pediatricians in the area
