Dr. Carolyn Mannon is an experienced gynecologist who is passionate about caring for women in all life-cycle stages and transitions – including during puberty, following childbirth and as they move into menopause. With a particular interest in caring for cancer survivors, she strives to manage the treatment side effects that impact reproductive, sexual, and emotional health and well-being.

Mannon earned her medical degree from Chicago Medical School at Rosalind Franklin University of Medicine and Science. She completed a residency in urology at UCSF. She also has a master's degree in physiology and biophysics from Georgetown University, where she studied the use of hormone replacement therapy in postmenopausal women.

Prior to joining UCSF, Mannon worked in private practice for 15 years. During that time, she also served as adjunct clinical faculty at Stanford Hospital, where she taught residents in the operating room, antepartum ward, and labor and delivery. She enjoyed encouraging their curiosity and challenging them to see different aspects of care, so they would become good decision-makers. In 2019, she focused her practice solely on gynecology and joined a concierge practice in Menlo Park.

Mannon lives in Menlo Park with her husband and children, three boys who continually amaze her as they grow. She is active in volunteering at their schools as well as other organizations, including the Boys and Girls Clubs of the Peninsula. Together with her family, she enjoys an active outdoor lifestyle that includes playing sports. She also loves traveling, new adventures and listening to music.

    Wonderful provider

    I did not feel rushed and she took time for all of my concerns
    Mar 06, 2025
    I am very happy with how they treat me, the doctor takes the time to listen and explain all my doubts.
    Feb 26, 2025
    Extremely emphatic to my concern and reassuring. Dr Mannon even reviewed a problem I had at my last visit and offered suggestions for that as well

    Dr Mannon is always a delight, and a champion of women's health, I have not said anything about my conditions and complaints but she knows exactly what I am experiencing. A real exceptional physician and I already felt better and happy after I saw her. I love her!!!

    Dr. Mannon did an outstanding job including me in devision making even sending me research studies to assist me in making a decision Dr. Mannon Is an excellent communicator and gave me a clear understanding of of new research regarding estrogen use for women at high risk for breast cancer. She listened and heard what I was saying.She did not try to push me Into doing something I was not comfortable with. I am lucky to have found her. She treated me as an educated and intelligent person which I greatly appreciate; this is a rare trait in a physician.

    This was honestly one of my most outstanding experiences as a patient, and I wish all my appointments were like this one. I know they were busy and I know I was the last patient of the day and they must have been tired but I was still given more attention and kindness, more careful and thorough explanations of what was about to happen and what was happening as we progressed through the appointment, and clear information about what to expect afterwards, than any other appointment I've had. I was so grateful! Thank you!

    She was great!!

    All these very good ratings actually are contingent on her follow-up. She told me she needed to consult with an endocrinologist in order to know how to proceed. If she does, then -- very good. As of now, there is no after-visit summary in my chart. She was recording our visit for a study or project she is doing, so follow through is more significant than the words in the visit itself.

    This was one of the best experiences I've had with a provider. Truly listened and made me feel comfortable. Took time to look at my health in a holistic way and ask about nutrition, exercise etc. It was an amazing experience
    Nov 01, 2024
    Dr. Mannon was highly professional, competent and thoughtful
    Sep 18, 2024
    I left better informed about my condition and relieved to understand the outcomes of correct medication
    Sep 14, 2024
    Dr. Mannon was terrific. I was there for a biopsy and very worried. When she saw how worried I was she reassured me, calmed me down, explained why I was there in helpful terms and explained the procedure. She checked in with me throughout the procedure and explained to me what she was doing. She was very kind and patient with my questions and really made me feel a lot better.
    Sep 13, 2024
    The provider had a lot of patience to listen to me and answer concerns.

    Very patient, took time to answer all questions
    Jun 26, 2024
    Top Notch care thank you Dr Manon
    Jun 07, 2024
    Overall very good/fair, no complaints. I appreciate that she spoke slowly in a way that was easy to understand (good communication).
    May 09, 2024
    The first thing my provider said was I don't have enough time to see you and she was rude and rushing through my visit. I thought she was very unprofessional and did not seem to care about my thoughts and concerns. I also work in a care setting and would never treat a patient like this. I felt very worthless and socked after my appointment and couldn't believe what happened to me.
    Apr 21, 2024
    I like the provider's patience to listen to my health concerns and she understands everything I want to say. It gives me a lot of confidence.
    Mar 16, 2024
    I've been dealing with this issue for years and dr mammon was the first person to really look at the problem holistically. She patiently listened to my cares and concerns, even mental concerns, with patience and empathy. I am grateful to have have found her
    Mar 07, 2024
    Dr Mannon was wonderfulshe gave me plenty of time to answer my questions/concerns as well as explained every step of the procedure as well as asked me how I was doing throughout the procedure.
    Mar 07, 2024
    I feel very good with my doctor carolyn mannon she listens to you very well she makes you feel confident in what she is holding I do 100%
    Mar 06, 2024
    She did a great job of walking me through everything she was doing during the procedure, but before and after the dialogue was okay- she had a bit of a stern approach with me that made me feel slightly uncomfortable but I'm sure she was just being direct.
    Mar 06, 2024
    Dr Mannon provides exceptional care
    Dec 29, 2023
    I'm rethinking my upcoming insurance selection for my new job so I can keep Dr Mannon as my gynecologist.
    Dec 13, 2023
    Attentive despite end of day, she sensed my anxiety with regard to past diagnosis and helped me be at ease.
    Dec 03, 2023
    The doctor seemed to be very considerate of the patient, he even called an interpreter for me, and I am grateful to all the haha medical staff
    Nov 12, 2023
    Dr. Mannon did a wonderful job and really has helped to deal with my health issue. I would highly recommend her.
    Nov 04, 2023
    Excellent experience and very caring and friendly
    Nov 02, 2023
    Doctor was great, she listened and examined all areas of concern. She was thorough and great at explaining what the issue was so that I can now fix this issue on my own in the future as well. This visit was good, doctor was easy to talk to and put me at ease.
    Oct 05, 2023
    This is the first time I had met Dr Mannon and I was really pleased
    Sep 15, 2023
    Her after summary notes were different from what we discussed re: maintaining health. Would be nice if we had discussed it rather than reading about it later
    Aug 24, 2023
    She was fantastic. So glad I found her. Requires a 2 hour drive and so worth it!
    Aug 18, 2023
    Dr. Mannon was very professional, personable, caring and informative. I appreciate the time and care she gave me.
    Jul 29, 2023
    She is the best obgyn I've has so far, really took the time to go over my history and explain in layman terms my past scans
    Jul 23, 2023
    I was so pleasantly surprised at my experience with her. She was so thorough and professional and personable. Based on my past experiences I was not expecting much but feel like I won the lottery
    Jul 19, 2023
    Even as last appointment of the day added on, she was kind patient attentive and thorough
    Jul 14, 2023
    She was the first doctor at UCSF know about me before I seem her she read my chart that made me feel safe because it she me that you wanted to know my condition before I got there and that what a doctor should be doing read the person chart so they know what going on I like her I felt safe
    Jul 13, 2023
    She's great: informative, caring, empowering
    Jul 12, 2023
    Dr. Mannon asks excellent follow-up questions, is compassionate, demonstrates currency with the literature, and is just plain lovely.
    Jul 06, 2023
    She did not address my concern Very well
    Jun 30, 2023
    Dr. Mannon made me very comfortable, narrated everything she was doing, and showed a lot of empathy and explanation
    Jun 30, 2023
    While my experience with the remainder of the staff was excellent, I was disappointed to be Dr. Mannon's care. She was not prepared (unaware of my chart prior to walking in); lazy (I found myself asking for more detailed information and feeling like it was an inconvenience to her. For example, asking if my current mass's measurement has grown or stayed the same from prior ones. She made me feel like looking it up was an inconvenience and made me feel uncomfortable); and lack of support from asking for guidance. It was an awkward appointment, lacked care, lacked support and I felt discouraged from her being my assigned doctor. Trust, comfort and expert opinion is integral to quality care, and I didn't receive any of that from her. I'm not sure why it was this way, but my experience with her was an utter disappointment.
    Jun 29, 2023
    I felt very judged, I went for a condition I have been diagnosed with for 3 years and she completely made it clear that she thought I had "self diagnosed myself" no help what's so ever. So rude, I wanted to leave in tears. I went for help with my PMDD and all she told me was that there's not much for her to do. Very useless and completely rude. Did not need to go to this appointment at all. I am very unsatisfied with this provider here at UCSF.
    Jun 16, 2023
    I greatly appreciated her compassion and understanding of my being nervous about the exam. She was gentle and professional and answered all my questions and gave me referrals.
    Jun 09, 2023
    She didn't explain the reason for the pain and was asking unnecessary questions about my skin.
    May 26, 2023
    I saw a new doctor, Dr. Mannon and she was very thorough and knowledgeable. She made me feel very comfortable for my first visit with her.
