    Dr. Dillon took time with me t look at all aspects of important lab work and diagnostic information for best outcome for my osteoporosis. He was knowledgeable about treatment options and listened to my questions and comments with respect. As a woman in my 80's I often experience "agism" and the unspoken sense that my health problems are due to my age and therefore do not warrant in-depth exploration of treatment options. Dr. Dillon behaved as a compassionate and competent partner in reviewing my concerns and arranging follow-up for best treatment options once thorough, up-to-date diagnostics clarify my current health status related to osteoporosis.

    Best experience I have had at UCONN Health - Dr Dillion took all the time needed to work with me on my diagnosis and it was the first time everything was explained to me in detail so that I could make a decision on the treatment. The staff there was also amazing.
