    She provided me with all the information I needed.

    In my first visit, Dr Dea seemed to be rushed (possibly running a bit behind schedule). She quickly explained what she wanted to do after a short exam and scheduled bloodwork to be done that day to establish a record for me, along with more tests. The second appointment went better, with better communication.

    I feel like she is usually better, but this visit she felt rushed and pushy and even gave me some misinformation, which was extremely frustrating. I like her and will stay for now, but I did not feel like she was interested in treating me like a factor in my own care this time, which is really never ok.

    Dr Dea is fantastic, she is so attentive and explains everything to me, so I fully understand my medical condition
