“Clean/New and efficient Office. I was seen within ten minutes of arrival.
Though my case was very cut and dried, the Dr. was thorough and did a proper exam. This was a First Visit Impression.”

“Thje whole experience for this Dermatologist is great. When I confirmed my
apointment the office texted me a few times to remind me of my appointment. When I went to the office, the wait time was just a few minutes. The staff was very friendly and the whole office was "spic and span". As for Dr. Porto, he was friendly, listened to my request and did the
procedure. This isn't the first time Dr. Porto worked on my problems so I am pleased with his work and would recommend him hiighly.”

I strongly advise anyone with HSA insurance to avoid Dr. Dennis Porto. Unlike most dermatologists, his office charges not only for the procedure but also for the time you spend in the office, and the rate is unbelievably high per hour. Even a short visit can turn into a shockingly high bill. If you’re an HSA holder looking to manage costs, stay far away from this practice.
November 18, 2025Andrey G.Verified patient
Overall great experience
October 30, 2025Tatyana G.Verified patient
Dr Porto is a skilled dermatologist who listens and is attentive to he Ned’s of his patient's. I have recommended family members, who I care deeply for, to see him.
The wait time is good and the office is spotless.
September 9, 2025Ira Z.Verified patient
Staff was friendly and attentive. Same for Dr. I got there early but had to wait my turn. I think no matter how early you come in they went by appt. People came in after me and they went before me. All in all it was a good experience.

August 10, 2025Saul K.Verified patient
I,m not interesting to him
July 10, 2025Sergey Y.Verified patient
I interacted with 3 people, and they all showed poor attitude.
First, some woman comes in & demands to see and take pics of everything. She's not even a medical professional. I didn't come for a non-medical professional to ask to see and take photos of my body. When I said that I rather just speak to the doctor, and didn't want pictures taken of everything, she stormed out of the room saying that she will tell the doctor that I'm "uncooperative and the doctor will be very upset with me!" Like this is kindergarten...
Then the doctors walks in and starts lecturing me that I need to let her take the pictures and tell her my medical problems "because this is their rule". Again, lecturing me like kindergarten. Then the Dr was obviously angry & rude and refused to do the smallest thing. He gave his diagnosis, which the woman was supposed to write down for me. But she told me that "I'm free to go". I asked her for the written diagnosis, but she stormed out of the room and disappeared

Dr. Porto listened patiently to me describing my symptoms and the factors that I believed caused them. He agreed that chemical exposure likely caused the rash on my arms. He prescribed medication that took care of the symptoms in less than a day. I went immediately from not being able to sleep at night to being on the mend. Great experience and I would see him again.
