What else would you like to say about your experience?
I had send an extensive document with many complex questions regarding my husbands disease, medications and current symptoms. Nurse Practioner Jessica Therien read it before coming in to the exam room and took as much time as we needed to address each and every question. I was so overwhelmed before this appointment but felt that she heard my concerns and truly cared about every symptom. My husband has a terminal disease that has many hard to handle symptoms. I am so thankful for her knowledge and dedication to see that we are heard and can obtain the best care possible. I hope she does not leave this office.

What else would you like to say about your experience?
I don't feel like I was being listened to at all during my visit because the NP was more focused on finding me a new provider. I have never been to another doctor where majority of the visit they spent trying to find me a different provider & focus less on my issues.

What else would you like to say about your experience?
My visit was great. The only complaint I have is that my appointment time was at 7:30 a.m. in the morning. I did not see the provider until 8 a.m. So it was 30 minutes behind schedule. That was disappointing. Otherwise, it was a good experience.
