I just had my first visit as a new patient with Dr. Fernando at Innovare Health Advocates. I was not only blown away by him but by the entire office staff. He spent 45 minutes with me attentively listening, was extremely thorough and very progressive in his thinking, VERY easy to talk to. He gives out his cell and he and his office staff (that ALSO were over the top friendly and caring) made it very clear that if you are a patient in their practice you are their top priority and will be well taken care of. He even visits his own patients in the hospital instead of being seen by a hospitalist. I feel truly blessed to have found Dr. Fernando and his practice.
