    At this appointment Dr. Buckle summarized what we've learned from the diagnostics and the Tumor Board. His explanation and recommendation for treatment was clear and well-supported by data. He answered all my questions and helped me feel confident that this is the best treatment option for me. I'm very thankful for all of the work he did to develop his recommendation.

    Very good as a choice doesn't capture the empathy, expertise and patient-centeredness of Geoffrey Buckle - the choice should be "excellent".

    Dr Buckles is an ideal consulting doctor. We can ask questions in depth without feeling at all rushed, which is very appreciated.

    Dr. Buckle's concern for the patient's quality of life is so comforting and reassuring. He explains all options that might be available for my care/treatments without pushing any particular option but only helping me to understand the options available. I couldn't ask for a more caring, compassionate, or supportive doctor.
