Would recommend him any day of the year
February 23, 2017Jnaid S.Verified patient
The secretary was out on vacation so the physician assistant doubled up as one. She was thorough and professional enough, but she was not very friendly. Dr. Klein has a no none sense attitude and cracked a few jokes. He was also through, and was courteous and professional enough. However, he was able to see me within 2 days notice. Overall, they could be friendlier!
December 29, 2016Lauren L.Verified patient
I met with Dr. Klein after having some stomach issues. His office calls you right after to make the appointment to tell you that you have a copay and that they only accept cash. They make that call before every appointment. He immediately recommended an endoscopy and colonoscopy at the first appointment. When I expressed concern that I didn't have extra money to pay out of pocket costs for any procedures, his assistant told me "don't worry about it. You're insurance covers it. If you receive any bills just bring them to us and we'll take care of it." A few weeks later, no diagnose other than "everything looks good and make sure you eat healthy," I'm still having the same issues and I've just received my third bill in a week for a large sum of money that zocdoc won't let me publish, that my insurance didn't cover. The office doesn't even send bills. They send Chase Quickpay notifications labeled "This is your deductible. Please pay ASAP." Naturally I called Dr. Klein when the third bill in four days came in the mail and he immediately struck an attitude with me telling me it's not his office's fault, they didn't know and that he doesn't work for free. He even had the audacity to chide me for calling him on the number provided on the bill after 7pm. Apparently it's his cell number. Mr. Klein and his team seem to care about one thing - collecting money from you. If money isn't an issue, he's a friendly guy before he presents you with the bill. I would however anticipate waiting at least an hour from your original appointment time to be seen. Enjoy the candies next to the receptionists desk. As far as I know you won't receive a bill for them.

In few words- I would highly recommend Dr Klein. Very helpful, funny, he made some jokes and chatted which actually made me feel much more comfortable and I wasn't embarrassed to talk to him. Stuff was funny and helpful especially the anesthesiologist and Miss Milana! They called me day after my colonoscopy to ask how I feel. Definitely recommending him!
August 12, 2016Aneta R.Verified patient
The staff (front desk) is pleasant and funny. They respected my timing and after noticing English was not my first language and that I was not familiar with doctors appointments in the US, they helped me understand the system.
It was my first visit to Dr Klein and I thought he is very approachable and knowledgeable. We discussed for a long time about my medical history and next steps for treatment, including next visit for endoscopy and its procedures. It felt very welcoming
July 19, 2016Elaine S.Verified patient
After waiting around 10-15 minutes (best part was how quick I was in and out), I was brought from the waiting room to the payment waiting room. Here I was told my copay, and when I handed my debit card was told, "we only accept cash... or a check." In my eyes this is extremely unprofessional and outdated. I had to run down the street and pull out cash, and then ask for a receipt after the nurse/receptionist/cashier stuffed my money in her drawer... I explained to them that not letting me know about payment options ahead of time was a bit unprofessional and also a hassle on all ends. After this I was taken into a room, put on a robe and Dr. Kline met with me. He made me pull up my robe... which I have NEVER been asked to do at any doctor for a checkup (I was in to ask about some lower abdomen pain).. and poked around a few times asking "does this hurt." After his "expert check" he told me to get my blood taken and then get a few ultrasounds and see him in 10 days for the results. He didn't offer up any ideas or reasons I could be in pain, or things to help in the meantime. I felt as if he just wanted more money from more visits. After this the nurse/receptionist/cashier came in and hastily drew my blood -- it was mildly painful, and I'm normally NEVER bothered by this procedure. She then hastily put a wad of gauze on my arm for about 30 seconds, said I was fine, and then pulled it off to find my arm still profusely bleeding. After this she stuck the wad of gauze back on my arm and TAPED it around my arm... To say she was rushing is an understatement -- it was extremely unprofessional. I booked a second appointment for politeness and to weigh my options, but will be cancelling all further appointments. This was an extremely uncomfortable visit overall, with no help in the end, whatsoever. Money and time wasted. I do not recommend this doctor.
August 6, 2016Emily M.Verified patient
Horrible.
- He asked if I had a boyfriend
- His nurse YELLED at me. I asked her to specify which type of blood tests she was looking for, and she would keep on yelling "When did you have it".
- They has no water!
My worst experience ever.

Dr. Michael Klein is GREAT. He was a great doctor who mixes compassion with humor, which is very good if you are a nervous patient.
However, the same cannot be said of his staff by any means. They were incredibly rude every single time they called and/or I went to his office. They just yell at you for your co-pay and basically hang up on you. They don't ask you anything else. It's all about the money. When I called for blood test results (that were already several days late), they said the doctor was not in and hung up on me. At the office they literally ignore you, and do not man the front desk. They hide in the back of the office (behind locked doors) where no one can see them until they decide to call your name.
The wait time is consistently awful. I waited for more than an hour after my appointment was supposedly scheduled for all three times I saw the doctor. Some people whom I was waiting with had been there for more than two hours. Given the fact that I had an issue that made it difficult to sit down, sitting in his waiting room for 1.5 hours after my appointment was scheduled for was beyond frustrating. What's worse, it was very clear that no one was back there getting treated, so we were all basically waiting for no reason.
Honestly, I can safely say that these are far and away the WORST receptionists that I have ever had the displeasure of meeting, and hence overall a poor patient experience. While the doctor was very friendly, his staff are AWFUL human beings!!!!!
While I would recommend this doctor 100%, his staff has consistently made the patient experience very unpleasant.

Very knowledgeable. Nice personality, easy to talk to. Loved the office, very cozy and comfortable. Extremely satisfied with my choice of this doctor.
April 27, 2016Kelly M.Verified patient
Other reviews about him are very accurate and spot on! The interaction was a bit weird and uncomfortable. He was asking me a lot of personal questions about my family and friends that I felt was not related and necessary to my treatment. He was quick to schedule me a colonoscopy procedure but given my interaction and the negative gut feeling I got from him I decided not to follow up with him. Furthermore his office and its facility is also very old and outdated leaving me very uncomfortable to receive any treatment from him.

Dr. Klein was great! He was very friendly as well as professional and seemed to really care about my well-being. He was very knowledgeable and really prioritizes you. I'm seeing him in two days for my follow up procedure. The only negative was that I waited 45 minutes before seeing Dr. Klein, but I guess that's not completely abnormal.
November 25, 2015Initials hidden
Dr Klein is pretty great, but his staff are terrible. They ignore you when you come in, I waited over 45 minutes every time I have come (had to keep going for urgent health reasons), and are blatantly rude and generally unhelpful. You have to pay cash and act weird when you ask for a receipt. The anesthesiologist gave my a huge blood bruise because of his hazardous application of my IV. Really not thrilled with them. As far as Dr Klein, I would say he is more interested in small talk than focusing on health. I wanted to talk about my health concerns and he kept changing the topic to my personal life. Don't want to talk about my significant other- just want to get better and figure out what I need to do to get there.

Dr. Klein was wonderful! He listened carefully to all my symptoms and made what could have been a truly embarrassing and awkward visit far less uncomfortable. He was very nice and friendly and managed to take my mind off of things by chatting about everyday stuff.
I was the only person there at the time of my appointment, so the wait was quite short. But I did see quite a few people in the waiting room when I got out, so I guess I lucked out and it depends on timing.

I've seen many Gastro's over the past 3 years and Dr Klein sticks out as being the most caring and sincere. Unlike most, he took the time to speak with me person to person. He was friendly and very easy to talk to.

Dr Klein was great and friendly. Satisfied with my visit, location is close to the subway and his colleagues are nice. Highly recommend.
November 3, 2014Safiya B.Verified patient
I must say, I was not impressed at first. My appointment began nearly 30 minutes late and the place doesn't take credit/debit cards.
Having said that, I had a very different opinion after I left. Dr. Klein was thorough and attentive in gathering my medical history, discussing my condition and lifestyle and told me a few new "fun facts" that might come in handy over time. Didn't encourage a colonoscopy (which is good because it's not technically indicated for me yet). Probably the longest consultation with a physician I've ever had. I left very optimistic about a long-term relationship.

The office assistants have very no customer service skills. The waiting time is extremely long. The doctor is a good doctor, it is very convenient that the doctor is able to perform a endoscopy at his office.
