Dr Ferstenberg is really nice and he is very thorough. I appreciate that he answers his own phone and is very straightforward. However, the wait time at his clinic is insane. Two visits, both 2+ hours. My negative review is notfor the doctor but for this front staff. The lady at the front desk is ridiculously rude, she won’t talk nicely no matter what and honestly I felt she wasn’t taking responsibility for her botched ability to manage scheduling. Walk-ins and folks with appointments went into the same queue.

I had to wait over 2 hours and he gave me 10 minutes of his time. He started it by saying his wife is picking him up in 30 minutes and he still had to get through two procedures. He alsoleft the door open and people would just walk in during our consultation.

Dr. Ferstenberg is a seasoned professional with an excellant bedside manner. I felt comfortable in his presence instantly and I am not a person that gets comfortable or confident with doctors immediately. His knowledge and expertise in hisprofression showed thru right from the first moment he spoke. He has a warm seasoned approach that makes you feel confident in his hands.

Yes he has 40years if experiences... however he interrupts and makes jokes when your trying to explain your issue. He was very arrogant and not apologetic for his reception staff being non existent and when I did find them they blatantlylied and said I was a liar about my wait time. Bit of a joke surgery to be honest and now I’ve found a more competent doctor with normal staff to assist. Go see this doctor if you have time to waste and are not serious about resolving your issues.

Worst 2 hours of my life! I waited at least 1 hour and fifteen minutes to see the doctor. The patient before me who was also a young woman like me came out crying and I should have known something waswrong at that point. When I finally saw him he spent the entire time talking down to me. “You know you must eat even if its just apple sauce etc.” “I know what I’m saying because ive been doing this for fourty years.” He also kept saying he’s just brutally honest. I told him fifteen minutes into the appointment that “You know I am 19 not 12 and I actually know a few things especially about my own body.” I also talked to him about the potential that I had a disease he isn’t specialized in and he said “you don’t even know what that is. Tell me what that is!” When i tried to describe my understanding. He cut me off, “no you are wrong. It’s...” This doctor has a huge ego and cannot speak to people like me with the respect I expect and deserve. He is unbearable to talk to. He also repeated several time “its your choice if you do .... but i have been doing this for forty years.” Simply put you dont have to tell me it’s my choice. Of course it is.

I met with Dr. Festenberg today for a dermatological consultation. Office is clean. 5 minutes before my appointment time, I was invited straight in to meet with him- no telephone game with NPs etc. His diagnosis was efficient, direct and honest.He could have very easily ordered frivolous tests and procedures, but that's not how he operates. Peace of mind comes with his impeccable record and vast, deep clinical experience. No matter what comes down the road, he'll be my go to Gatro professional for sure.

Dr. Ferstenberg is extremely patient and wants to ensure that you fully understand his 'diagnosis'. I saw him for a consultation and he was very thorough- while we only did a brief exam in his office, he went over my concernsin detail and did not let anyone in the office interrupt our discussion. He takes his time and doesn't move you in and out like many doctors do. Our conversation continued until I had no more questions left unanswered and told me to call him should I think of anything upon arriving home that day. Highly recommend!

The doctor is very experienced but a couple of things badly affected my experience. First, the wait was more than an hour and the front deske was not very welcoming. On top of that, the other doctor who shares the officespace kept yelling at people on the phone and the front deske staff. The other thing is that my appointment was disrupted multiple times - the door was always open and staff would come on and adk the doctor questions or get him to sign papers. I had never experienced something like this before and it made me very uncomfortable. There needs to he doctor-patient confidentiality and it can’t happen with an open door and people constantly walking in.
