  • Nov 16, 2019

    I was amazed by how much we covered in a single visit. She listens without judgment, and provides direct but compassionate feedback. I left with information ranging from plans for the toddler when baby #2 is born to breast pumps that might be better for me this time around, given my previous experience. Dr. Au is wonderful!

  • Nov 14, 2019

    Dr Au is caring and genuine. She listens attentively and is warm and caring. I would recommend her without reservation.

  • Nov 07, 2019

    Dr Au is the very best. She is my favorite doctor ever and that is saying a lot because I am married to a doctor. I ALWAYS feel taken care of by her and her team. She takes so much time to review my chart before I come in and that makes me feel amazing. She always answers my random questions and puts my mind at ease. I sure hope she gets a designated MA soon. She definitely deserves it and it would be nice to know that whenever I come in I’m seeing the same team.

    Dr Au is the very best doctor I?ve ever had. She was my light during my first labor and I?m so glad to see her often during my second pregnancy. She always helps me with my concerns and makes me feel better when I have a random freak out. She is so great that she definitely deserves a consistent medical assistant. I?ve noticed they?re always changing. They?re all nice but I think it would help Dr Au and she deserves it.

    My chronic abdominal ache remained undiagnosed for almost a year, and then Dr. Au felt around, asked me questions, and figured it out!She was also polite, compassionate, and knowledgeable. I couldn't ask for a better gynecologist.

  • Jun 25, 2019

    Dr Au is everything I hope to find in a provider. She is prepared, timely, efficient and thorough. She listens and responds, and it feels like she genuinely hears me and my concerns. While very efficient, she never makes you feel like she is rushing. She is personable and friendly, and closes the loop effectively. While the hill is inconvenient for me, I make the trip to see her specifically.
