This was the first time I was seen by this provider. She prescribed medication for my illness and explained why she chose that med for me based on my current symptoms, history and relevant lab work. I was impressed with how familiar she was with my history. The visit was seamless in that I felt I was picking up with someone I had seen before and who knew me.She ordered follow up labs to be done a few weeks after I completed my medication.

She came across as friendly and professional. I didn't have any concerns with her. I just don't feel like I've had enough interaction yet to fully evaluate her.

Overall, I thought the visit went well. The NP seemed concerned about my condition. My condition, parasomnia, is not very common and the medication used to treat Is one that medical providers get weary about prescribing. She was very thorough And understanding.

Takes a long time to get a specialist appointment (ie immunology) or medical imaging. Providers tend to downplay ""routine"" concerns and I don't always feel respected or validated.
