The doctor was a nice person and seemed to care about educating his assistant; however, as a patient I felt very rushed and the diagnosis of my condition left me feeling skeptical at best. After showing him an irritation on my skin, he told me a lot of it could be one thing or it could be another, with no real clarification other than googling images of other people's irritations. I left with a sample of a cream and a prescription that might or might not help, "but it's good to have in the house maybe if someone gets poison ivy". After going to the pharmacy that the Doctor recommended because he said my pharmacy would not have this cream in stock, I was told that with my insurance it would be hundreds of dollars to fill so of course I left the pharmacy. I left the doctor's office feeling worse about my slight skin irritation than when I went in, partially due to the fact that the doctor was throwing grand diagnosis around like I was in an episode of house, but also because for the 2 hours after I left the office, I was trying to call to change the pharmacy that my prescription would be filled at to my own, only to repeatedly be hung up on, transferred to a random mans cell phone who has no affiliations with the doctors office, and on more than one occasion be transferred to the Doctor voicemail box which is full and can not receive messages at this time. When I finally spoke to someone, they told me they were going to have a medical assistant call me back to help me within the hour, it has been over 4 hours and I am now confident I will not be receiving a call back. To say this office failed to meet my expectations is an understatement at best. I am appalled at the treatment I received both by the doctor and the reception staff, and will NOT be going back to this practice ever again.

I and my family have known Dr. Peredo since our sons played soccer together in the same team. Now I'm told because I haven't been to the office in over three years I'm a new patient I don't like that at all I feel like the practice which was a family practice is now a faceless conglomerate

Everything was great! This was my first time in the office, and after the paperwork was done, it was less than 5 minutes before I was called in. Then when I was in the exam room, I was seen right away by the nurse to go through some info. Two minutes later a PA came in, and less than five minutes after he left, he came back with the Dr to discuss course of treatment. Overall a highly pleasant experience, not to mention there is a pharmacy in the building so I didn't have to make any additional stops on my way home.

He is awesome. So personable. Takes his time with you. Explains everything clearly. Accommodating to your needs. Listens to you. Not pushy with medication. Has your best interest. Super sweet and nice. Always in a good mood. Has appointment times outside of work hours - who wants to/has time to take off for a doctor's appointment?! Has that doctor/patient relationship. The only dermo I feel comfortable with. Don't steal my dermo though!

Dr.Fastenberg has proven to be an exceptional doctor. He immediately was able to diagnose my rare skin condition during a fifteen minute hospital consult and knew exactly what to use for treatment . As far as his bed side manor goes he is very professional and takes adequate time to explain treatments and how the condition affects the body and also seemes to have a vast knowledge of best treatment options. I look forward to seeing him soon.
