Treatment Philosophy

I take an evidence based, patient centered approach to your evaluation and treatment. Each consultation will begin with listening to your questions and concerns, and a thorough medical history, physical examination, and review of any available imaging. Together we will decide on the best treatment course within the framework of evidence based gold standard medical care. I treat every patient with the same care and compassion that I would expect for myself and my family.

    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
