Our Patient Testimonials

  • 1000% patient-focused care! My mother relocated to Fort Lauderdale and it was Dr. Sizemore who diagnosed her life-threatening heart condition. No other Cardiologists detected it. Dr T. worked with us for over a year to develop a strategy and plan-of-action to get this critical procedure addressed. There's not enough words to describe the treatment, top-level service, and willingness to serve as a resource throughout the process. The Whole Team at Choice Physicians will go above & beyond for their patients. If you are looking for a medical practice that will be attentive to your individual needs, I highly recommend this one! They are LITERALLY life-savers.
    Joey Crawford
  • Both doctors are amazing and easy to deal with. I've tried 3 different doctors in the Fort Lauderdale area looking for someone who actually pays attention to their patients and cares. I found them with Choice Physicians. Easy to communicate with, beautiful/relaxed office...all around wonderful place to go! Highly recommended!
    Roger Posey
  • Both Dr. Ruiz and Dr. Sizemore are superlative Physicians and impeccable human beings. Their fund of knowledge is quite impressive but most important is the fact that they care! The patient comes first. You feel confident that your problems are being fully addressed. They are never rushed, you have their full attention, and you know that you are their priority. Physicians like these are few and far between.
    Joseph Perez
  • Dr. Sizemore-Riuz is always very helpful and will go out of her way to make sure I get the care needed. She is always accessible by phone should I have any questions, and she will follow up with me personally to make sure I am recovering well. Their office is very comfortable and has a home like feel. Much better than the normal doctor's office atmosphere. By far, the best doctor I have ever had!
    Katie Bausher
