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.
December 31, 2025Mary K.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.
December 19, 2025Kevin H.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.
December 1, 2025Mark B.Verified patient
Great provider!
November 22, 2025Scott H.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.
Less than 1 year agoShamari S.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.
November 5, 2025David M.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.
