The MAS Staff


Karin Ruiz, Patient Coordinator

Karin Ruiz is the Patient Coordinator at MAS. She specializes in patient relations, scheduling, and financial planning for surgeries and procedures. Karin also manages our Fly in for Surgery program to assist our national and international clientele with their trips to New York City for all our top cosmetic procedures.

Karin was born in Madrid, Spain, but grew up in the New York City area, and has lived in the city for many years. Karin attended Quinnipiac University where she studied Respiratory Therapy, and has worked as a senior certified respiratory therapist at some of the most renowned institutions in Manhattan, including New York University Hospital, Columbia Presbyterian Hospital, and the Memorial Sloan Kettering Cancer Center.

Karin’s medical background affords her a unique understanding of the issues that influence a patient’s decision to have cosmetic surgery, and allows her to provide advice and counseling that is much more helpful than the average patient coordinator. Karin is devoted to assisting patients in making educated decisions about surgery, guiding them through the process of scheduling and payment, and answering a variety of questions along the way. Karin is just as much of a perfectionist as Dr. Vendemia, and together they will see to it that every “i” is dotted and every “t” is crossed so that you have the most professional and enjoyable experience possible.

From the moment you speak with her on the phone, to the time she greets you when you enter the office, you’ll feel safe, secure, and very welcome.
