Dr simpson was able to accommodate an earlier visit for me due to my change in work schedule. Dr. Simpson was able to move forward with a requested biopsy as she saw it was necessary to r/o melanoma.

Providence Patient
I skipped the question about ease of getting an appointment, as this visit was a follow-up visit, I scheduled in advance at the time of my last visit. Dr Simpson ordered lab tests for me, however, I have not yet had the testing done, so, I also skipped the question on if the Dr's office followed up with me on test results, as they are not yet available.
Providence Patient
All my questions were answered in an easy to understand way. My doctor ordered my medication and it was ready for me at the pharmacy when I arrived.

Providence Patient
She is very good
Providence Patient
This was my first visit to this provider. I waited 5 months for the appointment, but it was a routine exam. After seeing my previous dermatologist every four months and always having lots of spots "zapped", I was surprised that only one spot was "zapped" and that my next visit is a year from now. She said she thought I was doing fine and exhibited no areas of concern so I'm taking this as a good thing.

Providence Patient
Phenomenal service overall.
Providence Patient
Dr. Simpson listen thoroughly to my issue as I was having a terrible skin rash throughout my body. Looking at all the medications I was taking, she quickly figured out I was allergic to one of them. I was able to stop taking this medication immediately, and with some medications she then prescribed for the itching, this issue started clearing up immediately.Thank you Dr. Simpson.
Providence Patient
It was a good experience. Everyone was friendly, helpful and efficient.
Providence Patient
Dr Simpson has been absolutely wonderful about addressing my concerns about swelling on my forehead that turned out to be cancerous.
Providence Patient
I was referred to a dermatologist (by my dr) because I have several new lumps and bumps on my body. According to Dr. Simpson, they are nothing. I felt that the dermatologist did not take me seriously and appeared annoyed during the appointment. Her lack of bedside manner left me feeling upset and, honestly, stupid for wasting everyone's time. I couldn't have gotten out of there fast enough. I have been under the impression that when there is a medical concern, it should be checked out. Right now, it seems that if I have a medical concern, I should ignore it because I hate feeling incompetent and stupid.
Providence Patient
Great care with Dr.Simpson and her team. My appts have always been fairly quick & informative, which I appreciate . Staff is always so welcoming and very sweet.
Providence Patient
Dr. Simpson has looked after my complicated skin health excellently for many years.
Providence Patient
Great!
