Hi; looking for an ENT...

[jesm]

If you are comfortable in “telephone” Spanish you best call in advance for “una cita con Doctora Hernández Hernández, por favor”.
The clinic phone number is 473- 102-3100. Receptionists likely will have limited English. I think she starts seeing patients at 10am. Like many physicians she may split her working hours between their private practice at the Clinic and duties elsewhere in the public sector, IMSS, SP.
An office visit should run between 400-700 pesos.
Hope all goes well.
