It was a pleasant experience all things considered.
Dr Pazionis is a wonderful doctor.She listens and discusses all questions I have about my health issues.
The whole office experience has been very good and my Dr is amazing
Dr. was helpful, concern for my questions. Kind THANK YOU Dr. Theresa Pazionis.
This was my first appointment with this doctor & her & her team are the best.
She is the most wonderful and caring doctor. Listens, explains and interested in all aspects of my recovery. She does everything possible for me as her patient and I know she truly cares about my health and well being. I feel very lucky that I was able to have her as my surgeon for a major cancer surgery.
was misinformed of having a "tumor" and referred to this dr. She reviewed all medical records, and concluded there was no tumor. She is definitely an one of the better doctors I have visited. Her bedside manner was perfect. I appreciate her taking the time to listen and review all the facts before making a diagnosis.
good
great experience.
Dr. Pazionis gave me real information on exactly what I need to do to get back to being able to be back to me being mobile.
Doctor really explains things in detail
