Dr Pazionis always goes above and beyond to get what I consider a more systems-oriented view of my health, and I am the better for it.
Awesome, Excellent, A+
I have been to so many doctors about this problem and Dr. Pzionis has been the only person I felt took me seriously and to be proactive in suggestions and tests. She really seemed to care and didn't just shrug and say there's nothing I can do. She is also the first person to not mention my weight when discussing a completely separate issue, which as someone who is overweight, but not obese, I appreciated so much. I will be following up with her in 6 months
All good
