"Dr. Ylonka Garcia Marotta is my primary care physician now for 6 years... She would take time to search other inexpensive medications that were affordable to my budget. She is a highly trained Bilingual Medical Doctor that cares about my health."

"I have to tell never have I ever dealt with a receptionist who thought they were a physician, telling a patient what they should be doing with their medical decisions... TERRIBLE!!!!!!!!"
