    Dr Accarino was fantastic, he understood my condition, helped guide me thru the time between now and 2 months from now when I have an endoscopy scheduled. As my throat is swelling randomly, we have no idea why until I get a look at my esophagus. The doctor shared strategies, medicines and techniques to control the swelling. He explained what he thought I had, and what the treatable course would be. I've never felt so heard or understood. I left with hope. This is terrifying, and I swam Alcatraz without a wetsuit, so I know how to control fear. This doctor is a rare gem.

    Took time to listen and also to explain and clarify my concerns and questions. That was greatly needed. He listened carefully. Shared knowledge on what I needed to know in order to discuss together best options. It seems that this doctor sincerely cares about the patient in front of him. This doctor seems to see past the "time clock" and into his patients concerns who are sitting in front of him. I think potentially that he really hears people.

    My entire appointment went great. The lady at the front desk was great. Very nice, friendly and helped so much. I didn't wait long and when I was taken back I didn't wait long to see the Dr either. He came back and asked questions, listened to me, answered all my questions and gave me a ton of paperwork wit information on the diagnosis I received that day. The whole appointment was amazing. I'm always nervous for new appts because being chronically ill I don't really feel listened to but he was truly wonderful. So helpful, kind, spent over an hour with me and we made a great plan moving forward. Very thankful for my appt, the staff and the clean facility!

    My daughter's care provider was very awesome. He helped me out understanding allergies and the allergies she doesn't have, which has helped me not be so stressed out about what she eats. And it has relieved a lot of like stress from my life to knowing that my daughter's care provider understood what her needs are and what my concerns are. They were an amazing team. They were very nice, very respectful. My daughter left very happy. She didn't mind the little pricks of the little allergy shots. They were very sweet to her, but all honestly, they were very awesome to me in understanding that, what my concerns are. And it was really nice to hear that my daughter does not have any allergies. That takes a lot of like stress away from a lot of situations in her life. especially birthday parties.

    Along with creeping decrepitude, my general discomfort increases with the growing age gap between myself and the...experts. However, Dr Accarino (maximum gap) had me at ease within a few minutes (not an easy thing to do). I was impressed with his ability to sift through my responses to narrow the range of issues, and a "what's next" going forward. Impressed as I was with the Doctor during the visit, I was increasingly amazed that within 24 hrs the blood analysis had been done, and Dr Accarino had been consulting with "a team" regarding some "unusual" results! Sharp. Perceptive. Dis-arming demeanor.
