Verified patient
Staff from the reception to the medical professionals to checkout were all incredibly welcoming and professional. The instructions were clear and concise, the doctor listened closely and addressed all my concerns
I was prescribed two prescriptions for POD. One topical and one oral. They didn’t even file it with my pharmacy at first or my insurance. I was later informed that my blue cross blue shield PPO insurance was rejecting the topical due to issues from the dermatology office. By far worst experience I’ve had at a clinic. My face in burning and I paid for a clinic visit to do absolutely nothing for me.
Verified patient
This was my first time going to a dermatologist and I was pretty nervous but the entire staff made me feel super comfortable from the initial nurse (I forget her name but she was lovely) to Dr Andrew. Dr Andrew calmly diagnosed me and gave me treatment options with a clear path forward. I would highly reccomend this office if you’re looking for a dermatologist.
Verified patient
I would for sure go back. I have heard good things about this provider and everything lived up to that. Fast in and out but with a good examination. He gave me a choice of options for treatment. After I told him which I choose, he told me that was probably the best option for now.
Verified patient
Great provider!
Verified patient
I have now visited Dr Mastro twice and both times have been really positive experiences. He and his team are very professional, efficient, and have great bedside manner.
Verified patient
As other reviews said, fast appointment but did not feel rushed! Informed them about experiences w/ my previous dermatologist, and I felt listened to and was provided options on how to proceed.
Verified patient
I never met the doctor. I am not sure who it is I met with. When you book a primary care physician you want an ongoing relationship with a care provider. This office doesn't give you that.
Andrew is a great doctor. He communicates clearly and lays out options with pros and cons for the patient to consider, backed by his experience. Really enjoy going there.
Verified patient
I came because I was suffering from eczema that had spread over my body after a few stints with topical steroids. The eczema (possibly TSW) was heavily infected and I was desperate for relief. The day of the visit I had discovered some antibiotics I had leftover from a ob-gyn visit and took them. I asked Andrew if the antibiotics would get rid of the infection in my skin and he said Yes. No questions asked for my underlining condition tho. I left with a prescription for new non-steroid creams and at the beginning of the 4 week process to start a biological. Within 2 days I had to go to the ER bc of the infection. I told ER that I was advised the antibiotics I was taking would cure the infection on my skin. They advised that was NOT the case and they had to cure me. The same day in the ER I get a call from this office that I was approved for the biological. Felt rushed and like they care more about my money than my health. Cancelled my future appointment and seeking help elsewhere

Ver positive experience. Was able to get an appointment quickly. Was seen right on time. Andrew Mastro listened to me completely and communicated treatment options clearly.
Verified patient
Appointment was quick (in a good way). My PA Andrew got straight to the point while making sure to explore all options and not moving forward with anything until he knew I understood the choice I was making. His MA was great as well. She was prepared and knowledgeable. Booking was easy and my prescriptions were filled incredibly fast with prompt delivery. Definitely recommend.
