    Dr Prionas is compassionate and treats each patient as an individual, not a statistic. He is well educated and has shown proven willingness to help his patients even when the path is unclear. He took the initiative to reach out to his colleagues and seek advice on my case then provided me sound options to best treat my case.

    I would not hesitate to recommend Dr Prionas to anyone. Now that I am one year out from my whole breast radiation treatment w/him I can say went extremely well because of his meticulous attention & care. He listens carefully, explains dense medical Information in a way that is easy for a patient to understand and most importantly, does not dismiss concerns as trivial.
