    Dr. Molloy was very thorough and clear about explaining my condition and recommending treatment. He was patient and a good listener and carefully answered all my questions. I was impressed with the statistics he provided demonstrating the effectiveness of his robotic-assisted methods. I didn't feel rushed and felt confident in my decision to proceed with the treatment he recommended, which was backed up by my previous research.
