Dear Dr. Valdez, Betty, Ana, Marlen and all the other administrative, either at the office or the hospital I want to say a big thank you for looking after me before, during and after my surgery. I am pleasantly surprised by your professionalism. The quality of service you offered is exceptional, the coordination, kindness and expertise are of a high level. I felt safe and have peace of mind. Thank you very much and à la prochaine! 🙂
