I love Dr. Zell! I was so happy to have new medical insurance so I could once again have Dr. Zell as my Rheumatologist. I had changed jobs and was on Kaiser.

National Jewish Health PatientFebruary, 2016
I am continually impressed with Dr.Zell. She is incredibly friendly and courteous. I always appreciate how much information she provides during our appointments. I appreciate how she explains all of my lab results in a way that is easy to understand. She is one of very few doctors who go out of their way to make sure their patients feel cared for, respected, and heard. I have recommended Dr. Zell to many friends and colleagues. She is an exceptional doctor, in every sense of the word.
