Julie parsonnet is a very nice doctor
She was incredibly connected with me and details of my case in every sense.. I look forward to the opportunity to work with her in the future.
Extremely personable, professional and knowledgeable.
I contracted a C-Difficile infection twice a few years ago and again one month ago due to prophylactic antibiotics (such as amoxicillin) prescribed to prevent post-surgery complications. My concern was heightened with the recurrence of the last infection and the need of antibiotics in the upcoming dental surgeries. I contacted the Stanford Infection Disease Clinic and requested video visit with Dr. Parsonnet uniquely qualified to advise on the issues of my concern. The visit was highly informative and productive. She appreciated my concerns and addressed them one by one with utmost clarity. I will be guided by her detailed recommendations. I am immensely grateful to Dr. Parsonnet for her generous help.
Dr. is awesome to work with!
Great doctor, but would rate low on appointment availability

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.
