Maria L. Wei

MD PhD

Dermatologist and melanoma specialist

Dr. Maria L. Wei is a dermatologist who specializes in melanoma and disorders of pigmentation, both acquired and inherited. She directs the UCSF Pigmented Lesions/Melanoma Surveillance Clinic, which cares for individuals with melanoma as well as patients at high risk for developing melanoma – a group that includes those with a family history of melanoma, those with genetic test results indicating a risk, and those with many moles or large congenital moles.

Wei leads a research laboratory that studies melanoma, investigating the biology of melanin-producing cells and how melanomas become resistant to treatment. The laboratory also seeks to understand the gender disparity in melanoma outcomes (why men and women have different outcomes) and is investigating novel biomarkers for melanoma (measurable substances that indicate the disease).

    Very good from start to finish
    Sep 22, 2024
    The care provider must have been having a bad day. Bed side manor left a lot to be desired that day.
    Sep 06, 2024
    I feel lucky and blessed to be in the care of Dr Wei. Thankyou.
    Sep 04, 2024
    Dr Wei is extra special. I feel grateful to have her as my Dr. She was so reassuring as to the rarity of melanoma returning after this many years. She did a full body annual check up.

    Maria Wei is an outstanding clinician, whose reputation as such proceeds her. I've found her to be a diligent diagnostician, and I have recommended her to people who ask me for my thoughts regarding which of many highly capable physicians @ UCSF to see If they've dermatology concerns, when their concerns Involve skin cancer, particularly if Melanoma is chief among those concerns due to family history et al. Maria Wei is the one physician I'd recommend without reservation.

    May 24, 2024
    Dr wei is a very knowledgeable, caring and respectful physician.
    May 24, 2024
    This was my very first visit to this care provider, but the visit time was limited. The care provider seemed rushing the visit, not discussing in detail about my medical condition.
    May 15, 2024
    I feel that the doctor did not explain my options.I do not know the severity of my skin issue, would like better explanation. I was told I have to wait a week to find out what is going on.

    Excellent, the doctor explained very well everything we have to do to improve the health condition.
    Jan 05, 2024
    Dr Wei is simply the best!
    Jan 03, 2024
    My appointment started on time, the nurse and physician were amazing. I waited a long time for the appointment but it was well worth the wait.
    Dec 28, 2023
    I was told to upload my genetic test results regarding melanoma and I can't figure out where to upload them.
    Dec 26, 2023
    Dr. Wei was very friendly. She said she had requested the slides of my melanoma biopsy and would await those before deciding how to proceed. No timeline was given on when we might hear back regarding next steps.
    Dec 22, 2023
    Dr Wei is very efficient and thorough
    Dec 17, 2023
    Excellent care and expertise!
    Dec 07, 2023

    Nov 29, 2023
    Dr Maria Wei is a very special member of the UCSF derma team.
    Nov 29, 2023
    Dr Wei is excellent!
    Nov 17, 2023
    Dr. Wei was in a hurry and told me so she did not have time to give me a full body exam and that Idid not need on for another s 6 months and then as I mentioned her schedule is not open... The appointment was rushed and I am not happy with that.
    Nov 15, 2023
    Dr. Wei is caring and answers questions. An excellent physician.
    Nov 03, 2023
    It was a pleasant experience considering the stage of my melanoma.
    Nov 02, 2023

    Dr Wei is Awesome! I've had a lot of dermatology issues and Dr. Wei has literally saved my life. She is extremely knowledgeable, great communicator and just great at what she does. I really appreciate the care given to me by Dr Wei and all of UCSF!
    Oct 08, 2023
    Dr. Wei is the BEST of the BEST!!
    Oct 06, 2023
    She was excellent!
    Sep 28, 2023
    Dr Wei is amazing seems like over scheduling her is always the issue need to schedule less patients per day always 45-1 hour wait time
    Sep 28, 2023
    I came in to see Dr Wei as my regular provider did not have appt available for awhile. After waiting for so long I was frustrated by the time the doctor came in and she was not receptive to that frustration (am sure she had a long day as well so I get it) but she made me feel even worse about being there as I came in sooner than she felt I should be getting a follow up (my regular doctor said every 6 months is fine and she felt a year was sufficient, and I came in sooner than 6 months). I think the appt just started off on the wrong foot but I felt really bad after leaving, and these appointments are stressful as it is.
    Sep 27, 2023
    Exceptional, professional and empathetic
    Sep 23, 2023
    Provider seemed pressed for time. Exam seemed more rushed than usual. Concerned that my previous health problems were not taken into account.
    Sep 21, 2023
    Maria is amazing!
    Sep 15, 2023
    Excellent, thank you!
    Sep 14, 2023
    Dr Wei was kind and considerate. It took us a minute to get our communication style down but that's to be expected. She was reassuring about my skin care.
    Sep 01, 2023
    I really like Dr. Wei. I gained additional information from her. Thank you. I like the printout with the after visit summary.
    Aug 30, 2023
    Very good
    Aug 23, 2023
    I felt that the doctor was highly competent and trusted her medical decisions. I am grateful I was able to eventually get an appointment her. However, like the assistant, she was clearly under too much time pressure to encourage questions and give thorough explanations. The experience from the check in person to the assistant to the doctor visit left me feeling the stress that they clearly feel. I wish there had been time to ask questions about the various skin conditions and about preventative care. I noticed that after visit notes had written in them that things were "discussed" with the patient that were never even mentioned. Presumably these are automatically included in every note whether or not they are actually discussed. Let me be clear that I felt that the doctor was highly competent and I'm sure if she were under less time pressure, she would have been more patient. I felt for her and the staff for having to rush like they were in some sort of race. That time pressure very at did not make for a better patient experience. Care at UCSF is expensive. I would expect the doctors and staff to have working conditions that allow them to make patients feel comfortable.
    Aug 18, 2023
    This was my first visit with this doctor and I z was very happy.
    Aug 14, 2023
    I am a continuing patient. Dr. Wei is a fantastic dermatology physician in every way. She is consistently excellent.
    Aug 11, 2023
    I was grateful to be scheduled with a care provider who was professor with impressive expertise. I believe this is the most important consideration. It was not on the above list.
    Aug 04, 2023
    She was very thorough and explained things well.
    Aug 03, 2023
    Dr, Wei is outstanding. I have a lot of serious and I'm extremely confident in her care
    Aug 02, 2023
    I'm still a bit confused about the care of the wound going forward.
    Jul 28, 2023
    Dr. Wei is a wonderful and talented melanoma specialist. I appreciate being able to see her.
    Jul 14, 2023
    Excellent in every way.
    Jul 05, 2023
    It was my first time seeing this physician. I found her condescending and curt. I do not plan to see her again.
    Jun 29, 2023
    She seemed thorough and friendly, but examined me very quickly, probably because she was running an hour late. I did not get the impression that she was distracted, and I was not particularly worried that she missed some thing.
    Jun 29, 2023
    Best melanoma clinic in California. But appointment scheduling and lateness are a big problem
    Jun 28, 2023
    Her instructions were clear and fast. I had to listen hard to remember her instructions. I just wished she paused and gave me a chance to ask questions.
    Jun 23, 2023
    Dr. Wei care makes up for the difficulties in scheduling
    Jun 17, 2023
    Health care is challenging but the care that I receive from Dr Wei is OUTSTANDING; she is both an excellent physician and human being! Thank you!
    Jun 16, 2023
    My only issue was the wait time. If UCSF is going to ask me to be 15 minutes early to my appointment then they shouldn't make me wait an additional 45 minutes. Makes no sense.
    Jun 02, 2023
    Dr Wei is an exceptional physician. Incredibly competent and efficient. She welcomes any questions and concerns you have. I never feel hurried. I have so much confidence In her. Seeing a dermatologist on an ongoing basis Is stressful; she makes It a bearable experience.
    Jun 01, 2023
    The wait time is the sole issue, but it's significant
    May 24, 2023
    I think Dr. Wei is an excellent doctor and she is very attentive and complete in her exams.
    May 13, 2023
    She was best or second bets ever.
    May 05, 2023
    Exceptional care. Extremely knowledgeable. Feel so fortunate to have such a dedicated professional caring for me.
    May 04, 2023
    Very good experience
    May 04, 2023
    I love Dr. Wei, I truly believe she cares about her patients.
    Apr 28, 2023
    Clear friendly and professional communication.
    Apr 26, 2023
    Very professional, efficient, caring
    Apr 21, 2023
    The meeting was delayed and everything felt hurried.
    Apr 13, 2023
    Brilliant physician and diagnostician! Extraordinarily competent, caring, compassionate, friendly, and excellent communicator!
    Apr 12, 2023
    Dr Wei spent maybe 5 minutes with me. She was obviously rushed and disinterested. My prior meetings with her were not like this. I will be looking for a new dermatologist.
    Apr 07, 2023
    She was vert professional and took extra time to explain things to us. Very personal and likable. This is the first time I have seen her and I plan to keep on seeing her as needed.
    Apr 05, 2023
    Very short visit.
    Mar 23, 2023
    Dr. Wei is great! My complaints are about the process of getting to see her.
    Mar 22, 2023
    --Dr. Wei is excellent!
    Mar 17, 2023
    Dr Wei did not listen to my original diagnosis and went on and on about how I can only take less than 5 mins of shower. She didn't listen to me, she just kept going on and on about what she thinks my needs are. I will make another appt w a different physician.
    Feb 25, 2023
    Dr. Wei is exceptional
    Feb 24, 2023
    Dr, Wei is a great doctor and needs the organization to support her work and care for her patients.She caught my cancer immediately and I had it removed. She continues to impress me with her professional and caring approach.
    Feb 23, 2023
    Didn't get exact timeline for next appointment, but usually that happens on follow up a few days later anyway
    Feb 22, 2023
    Dr. Wei is an excellent care provider.
    Feb 20, 2023
    Dr. Wei seems distracted and stressed this visit when compared to previous visits perhaps due to clinic running late.
    Feb 15, 2023
    Dr Wei is extremely knowledgeable, professional and easy to talk with
    Feb 11, 2023
    I was referred to Dr. Wei for a skin mapping procedure. She was super thorough and ended up pointing me toward genetic testing, which came to me as a surprise. She was very thorough In delving deep into my family history of all cancers. I didn't walk away knowing exactly how it would benefit me and found I was kind of piecing it together for myself. That being said, my brain is slow to process unexpected information and there were certainly follow up questions I could have asked but didn't think of at the time. I haven't gone back on the portal to ask them yet, as my visit was only a couple of days ago.
    Feb 09, 2023
    The total wait time for my appointment from the time I arrived to the time I left the office was about 2 hours. This is too long to wait for quality care.
    Feb 06, 2023
    Dr. Wei is excellent in all areas
    Feb 03, 2023
    Dr. Was very helpful and provided me with a clear plan for care
    Feb 03, 2023
    Not follow up. Awaiting two prescriptions.
    Feb 03, 2023
    One of the best dermatologist I've ever been too. She is great!
    Feb 02, 2023
    She has always been great
    Feb 02, 2023
    Given the office issues - but care is more important. Why the trade off at a Magnet hospital?
    Jan 26, 2023
    Both the resident and Dr wei were wonderful
    Jan 26, 2023
    Dr. Wei is outstanding. Her expertise and devoted care with an exceptional bedside manner is rare. I am very grateful for her attentiveness and continued care.
    Jan 06, 2023
    Provider is excellent and very thorough
    Dec 27, 2022
    Dr Wei was nice. But I wish I could have had a more careful examination of my skin. And discussion of my skin. It was a super quick view of my skin. Maybe she's that good. But I prefer informative discussions that help me feel confident going forward on prevention of cancer cells.
    Nov 27, 2022
    She was moving fast, not much time to talk. But since this was my second time seeing her, I know she's careful and attentive.
    Nov 24, 2022
    I am sure the doctor is knowledgeable and experienced, though I don't find her to be warm, relational, or interested in the health issue I'm working with, and possible solutions in treatment. She may be overworked as she's rushed and seems impatient with questions. Particularly when treatment recommendations involve side effects that feel important to discuss. So I can make informed choices about treatment that has an impact on my quality of life. She doesn't seem understanding, just busy and impatient.
