Dr.Kornreich is an amazing doctor - he knows within a millisecond what's needed - explains thoroughly what's happening - yes he is busy but that is just a testament to his expertise! He has a wonderful sense of humor and I always leave his office with a smile!! I trust him implicitly with the care of my entire family!!

Horrific and condescending demeanor. I will never go back to a dermatologist that belittled me for pointing out something that was actually cancer. He is incompetent and vile!
WORST experience at a doctor's office in my entire life. This man is a salesman. I have never had acne in my entire life. Last month, I had a flare up for some reason and my skin got red and blotchy. Without even hearing my story or how my skin progressed and really before even looking at me, he looked right into my eyes and said, "WOW! You NEED me." He immediately recommended accutane (never would I go on that). This visit was a total sales pitch.

Unfortunately couldn't get past the women who set the appointments. It was very funny Having me call office to office with the same result of no one understanding why I needed to have my daughter seen by a Dermo because of a sore on her breast. That was nothing important to the office staff . Sorry I can't rate the doctor but his staff get a BIG ZERO

Very very high on himself. He thinks he's brilliant. Office visits are too fast. He misses things and that's why I no longer go to him. He will remove things that are really cosmetic without charging you----of course he'll rip the insurance company for it. He's into seeing as many patients as possible in his work day. From personal observations of his reactions he seems like a control freak who doesn't deal well with the unexpected or questioning of his medical care.

He is wonderful. Very informative, but gets to the point quickly. He has always treated me with respect and consideration. He's super busy, but will always take the time to answer all my questions and concerns.

He's a nasty piece of work under that phony almost giggly front. Find a doctor who can relate to patients with serious problems. He is certainly not the one. He needs help ---- of the head doctor kind!

I would never go back to Dr. Kornreich. Long story short I my first and last had an appointment with him. It was at 6PM and I was not in a room until 7PM. Did not see the doctor until 7:10PM. I was in for a simple wart removal, which he did not do. I informed him that I had waited so long, he did not offer an apology rather saying I was hostile and said there would be no fee for seeing him. Someone needs to inform the staff and him there dealings with patients needs to improve.
