    It's taken a year for me to get seen at UCSF Allergy. My PCP contract/referals with your dept was denied multiple times. So to have Lulu's full attention and thorough in-take In light of multiple tests available for her review from GI, Blood screenings, derma evals, was very much needed, and appreciated. I look forward to working with her. She one of the best providers I've dealt with in the past year.

    Care provider is very knowledgeable and attentive to patient's all possible related asthma and eczema issues. Very constructive recommendation and referrals to relevant specialists from the very beginning. As a result, not only my asthma had very encouraging progress, my serious hives problem was cured due to her timely referral to the right dermatology specialist. Care provider also has proactive and timely follow-up on patient's health progress.

    Dr. Lulu Tsao really listens. I had goofy but potentially serious concerns that I emailed a while ago. She listened & addressed them, making sure I was happy with the outcome. She makes me feel like I'm in charge of my body & she is in charge of caring for it. To feel heard is rare & wonderful. And that's what she is. I ask a lot of questions, each is answered & she is always thoughtful & informative. I really feel as though I am being cared for. That's a fantastic feeling. Yay! She is the best! I have already recommended her to two family members. I'm her newest cheerleader.

    Dr. Tsao was exceptional! She listened to all my concerns and addressed all the questions I had and was very polite. She also referred me to a dermatologist within the UCSF network for a patch test, so I could try to further understand what caused my eczema flare up. In addition, I had concerns about billing and she offered to write a letter stating medical necessity if my insurance denied my claim.
