I am so fortunate to have chosen Mark Kogan, MD as my physician. He is compassionate, kind and very knowledgeable. He is patient, respectful and willing to really listen to his patients. He goes out of his way to make sure his patients are taken care of. I have always felt that we are working together as a team and I have actually never experienced the level of care I have received here at any other physician’s office. I am old so that’s quite a few offices and physicians.

Dr Kogan was excellent, he focused quickly on my particular gut issues and we discussed several ways to address them. He's easy to talk to, and listens. I left the appt feeling calmer and more focused about getting better.

Like many offices now, the staff seems a bit green and sparse. My suggestion is to plan well in advance for the paperwork they need, and also to set up their specific video app. Phone turnaround time may be a day or two-

It was a pleasure to have seen Dr. Mark Kogan, from the cheerful & professional assistance who called me to confirm I was coming on time to her welcome and courteous service I had nothing but satisfaction.

Dr. Kogan is am MD who listens to his patient without interruption and ask you question to further understand your ailments. He is not one of those doctors who act like a demi-god, try to finish up your statement and goes on lecturing you what you need to do before understanding your problem. I had seen another Gastroenterologist 2 months before for bloating and gas who didn't bother to listen to me but gave me some lecture on what foods that I should avoid eating and sent me cut and past staff that I can get by browsing the web. It took me 2 months to get an appointment with Dr. Kogan after searching for the right doctor.

I highly recommend Dr. Kogan for anyone who like to see a doctor that will listen to their problem and provide them with proper diagnostic. One thing that I don't want to leave out is that Dr, Kogan is very personable and make you feel at ease with his warm welcome.
