    Dr. Baron is gruff and does not have a very good bedside manner. He is very knowledgeable and has very good diagnostic skills but is not very friendly does not suffer fools and appears to be frustrated with my lack of complete adherence to everything he suggests. I sometimes wonder if he is a better administrator than a clinician since I don't know if he enjoys directly dealing with patients.

    Dr Baron is an excellent DR! He participated in my health concerns compassionately and with respect and patience! Answer all my questions and explains well. I feel that I can trust in his experience and knowledge and yet I feel as we are a team in my health care

    Far too long to be filling out. It feels a little excessive. Can we shorten it for customers and patience going forward that would be appreciated

    Very experienced and professional. My regular doctor for a long time.

    The provider who was energized seemed more concerned than usual about time efficiency and time usage--about moving things along. Fortunately I made a written list of the things to discuss. Without the list I might have missed an item -- completely or partially.

    I feel so fortunate to have Dr Baron as my pcp. He fits every ideal I had of a physician which means a lot to me as a retired physician myself. He is kind empathetic wise and pragmatic

    I've worked with Dr. Baron for less than a year after my prior provider retired. I have enjoyed working with him. He provides me the level of information that I'm interested in and proactively includes me in decisions about my care.

    This was my first appointment with Dr. Baron and he was very professional and attentive to my medical needs. He went above and beyond my expectations. Dr. Baron is the true definition of what a medical provider should be compassionate and explained everything thoroughly. I felt respected and heard at my visit.
