I have been seeing Dr. Mackool for a very long time and really do think she is an excellent physician. It's just so difficult to get an appointment with her and she is always so behind. I make an extra effort to be early for all of my medical appointments and it is frustrating to not be shown the same courtesy. I should not have to block 3- 4 hours of my day for a dermatology appointment which is what it often is when I factor in commute time to and from and then the appointment time.

Dr. Mackool was kind and listened to me talk about my history with derm, asked me social quetions and was respectful in the room. She asked me if I had any active concerns and I watched her document them, however she did not ask me any questions about them or look at those parts of my body in detail or discuss a treatment plan OR why she was not concerned about them. She was hyper-focused on a resolved issue in my problem list that has not been a concern for years, was ruled out by other specialists and was not a reason for my visit. She prescribed me a medication for a minor aesthetic problem that I am not interested in taking and did not discuss risks/benefits of a medication that comes with specific instructions and a laundry list of warnings, specifically for women of child bearing age, which I am. [redacted] I felt rushed, likely because I was only in for a skin check and have no active problems in her eyes. That being said, she is clearly an excellent dermatologist who is well respected in the office, and I would return to her for any significant issues,[redacted]

[redacted] she was very rushed, my daughter, has some developmental disabilities and rather than talking to my daughter who was the patient, she immediately realized it would be quicker to talk to me, the mother, and she ignored mostly my daughter. She didn't really explain what was going to happen other than she used the phrase after looking at a growth on her lip that, yep, that's worrisome, we need to have a surgeon look at that. They'll take it off in the office. And then she got up and left, which, was concerning and left us with a lot of questions and a lot of worry. [redacted]

[redacted] I was brought back to a room, spoke with a resident, the resident started to scan my body for moles, and Dr. Mackool didn't come in the room until 9:45. I had expressed that the body scan is important to me because it's been a while since my last body scan and both of my grandfathers had skin cancer. The resident continues to inspect my skin and Dr. Mackool goes through my history with me and determines I have 6 different risk factors that could contribute to melanoma. She takes a look at 1 or 2 moles and then gets a phone call and steps out of the room. The resident continues with my appointment inspecting the moles and asking me questions. After the 5 minute phone call, she comes back in, inspects 1 or 2 more moles, asks if I have any questions and then just leaves. All in all it felt like she only spent 10 or so minutes with me and had to leave for a good chunk of time to take the phone call. I feel like maybe there were areas or moles the doctor might have missed and areas the resident saw but the doctor did not. I'm sure the residents are great, but for someone who was told they have 6 risk factors and a history of melanoma, I wanted more reassurance from the doctor in looking at my moles that I was okay.
