I have been seeing Dr Echavez for over 2.5 years ever since I saw him back in April 2014 when he (perfectly) fixed a Belotero job that a SF dermatologist had placed incorrectly. He is very talented with his work and also very kind. His office assistant Karla is also great. They never fail to call after any visit and they genuinely care about your results, pocketbook, appearance and feelings. I highly recommend.
