Dr. Parsonnet is WONDERFUL- thank you!
Dr. Parsonnet was outstanding. I so appreciate her knowledge and sensitivity to my concerns. She is an exceptional physician.
Dr. Parsonnet answered all questions I had for her. She made me feel at ease and relaxed.
The doctor was fantastic. I loved her attitude and humor. I was born at Stanford and love this medical staff.
Dr. Parsonnet is one of the best doctors I have ever had. She goes above and beyond, during my last visit she contacted two other doctors to get support for me in nutrition, recommending a diet change to support my kidney health. She called on a Saturday to update me on my recent labs! Amazing, caring doctor!
Dr. Parsonnet is a great doctor who spent time explaining things to me.
No problem. Satisfied.
The doctors explained every question and answers to where I understood. I felt very good talking to them. Actually I felt at home, not very many doctor's appt. are comfortable.
The ID tem in general lacks bedside manner. Even Dr. Blackburn's team.
This visit was MUCH better than the 1st less wait time to see dr. & the dr. was much more helpful.
Dr. Parsonnet offered to attend a follow-up visit I had scheduled w/Dr. Kwong to eliminate one extra trip to Stanford from my home in Santa Cruz. Very kind and considerate.
Wonderful person, thoughtful, well prepared, good listener, excellent or reaching out to other express around the country.
Julie Parsonnet is the best physician I have ever seen. I could tell she truly cared about me and would check up on me personally. Her personal touch of caring combined with her very strong knowledge make her truly amazing!!
Dr. Multani & Dr. Parsonnet are both awesome. Very knowledgeable. I trust them both I will miss Dr. Multani.
Doctor did not have all info on my status - but appreciated info I shared with her. She was interrupted during my visit but seemed to stay focused.
I've told everyone what a great experience this was.
Dr. Parsonnet is exactly how all Dr.'s should be.
Dr. Parsonnet is "GREAT."
