If I could I would give zero stars. This Dr is deceptively nice and seemingly competent. I considered suing him for malpractice after I found that: (a) I didn't have the asthma he'd been treating me for 2 years, and (b) he falsely diagnosed me with pneumonia not once but twice in 3 months. It was game over when I overheard him tell someone he thought they had pneumonia. I swear I recognized "my" chest x-ray in a google image search. That's when I went to Weill Cornell for a second opinion. I managed to get photos of my x-rays from the receptionist, and they showed clear lungs. I immediately got off some very nasty lung medicine that caused joint pain, breathing trouble, chest pain and acid reflux. At the time I was getting blood work weekly to figure out what was wrong. The medicine I was prescribed was so aggressive and unusual that the pulmonary specialist asked if the prescribing doctor was outside the U.S. I followed the specialist's advice, and never went back! Meds free and never felt better. read more

Total quack. He tells you have something serious and makes up symptoms you don't have so that he can order extra tests. If you try to ask him a question he yells at you. He orders extra tests and X-rays so he can get paid more by the insurance companies. He's a scam artist. Don't go to him unless you enjoy being spoken to like a complete idiot. Also the nurse didn't know how to use a thermometer. I know his diagnoses were wrong because I went to an actual doctor the next day who told me I just had a virus. Also I didn't have the symptoms he insisted I had. He's taking risks with people's health in order to increase the fees from the insurance companies. Boooooooo read more

I live in the neighborhood so it's convenient to have a doctor nearby (Tues., Weds. Fri & Sat if i recall correctly). Dr. Kaminski is very friendly and sympathetic. I came in for a regular checkup and he was very attentive. I'm also quite surprised by the review of his outburst. He is usually very busy with taking care of his patients, so I wouldn't be alarmed if he seems rushed. read more

I went to Mark Kaminski for an annual physical and before even doing a physical or taking a proper history he diagnosed me with asthma and had me doing a nebulizer treatment. I had never presented with any signs or symptoms of asthma and he never even listened to bilateral breath sounds never mind do a real assessment on me at all. This guy needs to have his license taken away. When I received my insurance statement I was charged for a physical in addition to an asthma exacerbation, this guy is a total scam. read more

He's a great general practitioner AND accepts most insurance, even my crappy GHI. I can always get a timely appointment, and have rarely had to wait long to see him. His office is super clean and his staff are really great and thoughtful. I use him for general care (i.e. flu, bronchitis, UTI) because I like an accessible local GP that is up to date and will save me the trip to the city. Which is priceless if you are feeling all ick and out of whack. read more

3 weeks ago I was badly bitten by a cat, I called doctor Kamiński's office they immediately took me without appointment for check up, finds out it was very bad infection.. but antibiotics worked and right now I'm all healthy and thankful. read more

I'm surprised at the review of his outburst. He's always been very professional and sincere, and I'm very thankful that he diagnosed my asthma for the first time in my life at age 39! He's also very pragmatic in regards to working with people without insurance, and will keep the visits as cheap and infrequent as possible. read more

Extremely unhelpful and rude staff. There was a discrepancy with my insurance due to an office typo in my contract number and the manager "Paul" was very difficult and rude to deal with. This minor problem was dragged on and on due to the inefficient and lazy staff. Terrible customer service!!! read more

As an existing patient with health insurance, when I make an appointment, I expect to be seen. I changed insurance and because they could not get in touch with the insurance company, the doctor would not see me. I told them that I would pay with a credit card and then seek reimbursement from my insurance and he would still not see me. I love wasting mornings at a doctor's office. read more

So intelligent, very careful to answer all my questions and even drew a diagram. There wasn't one thing he didn't do without explaining it first-/ and the receptionist is like sunshine in a person. Every experience was great. read more

Went for a physical and was diagnosed with bronchitis and asthma. Prescribed me an inhaler (which i never used) even though i didn't feel sick or short of breath at all. Then got a bill for extra charges that the insurance company wouldn't pay. Feels like a scam to me. This is not the first review here that has gone along these lines. read more

Same. Fake asthma. Used the inhaler even though I knew better that I didn't have it, but hey I'm not a doctor, maybe I developed it at an advanced age but nope. Years later floated the idea maybe I had asthma again, I shut it down so I didn't gave to go back on the machine. Fake pneumonia was last straw. X-ray looked clear, I made them email me an image and sent it to 3 professionals to make sure I wasn't crazy. I didn't have the symptoms. Didn't even take my temperature- went straight to the X-ray machine. I missed Thanksgiving with my family over it, I was afraid of giving my Grandma pneumonia until I looked into it further. The X-ray wasn't that expensive I just don't get what he has to gain by giving everyone one. Kick backs from pharmaceutical company? Fetish with lung porn? No clue. But at least you could get an appointment on short notice and he's friendly. Other than fake news other visits were fine. read more

look, the guy is really nice, seems to sincerely want to help you, and has a lot of great tech right in the office (x-ray machine, breathing tests, etc.), but just like with the couple people below, he incorrectly (and rather quickly) diagnosed me with pneumonia. I went to a pulmonologist, who said I didn't have it. Went back to Dr. Kaminski and he told me the pulmonologist was wrong. So I went to another pulmonologist who ran xrays and a couple of additional tests and said I have no pneumonia. read more

Great place. Dr. Mark is extremely knowlageable and professional. Will take the time to answer any and all questions. What really sets him apart is that you can really tell he actually really cares about his patients. I won't go anywhere els read more

This guy sucks ass! Arrogant and very unprofessional. He decided to diagnose me with something pretty serious without actually doing any of the tests that would be required to confirm this certain diagnosis. Since I am not a doctor I didn't know to question him so left his office shaken up, crying and freaking out about what he told me was wrong w me... he started me on all kinds of medications that cost me almost $200. When i went to the pharmacy and she saw what medications he had me getting she started to question it and told me i should get another opinion maybe bc its not common for a doctor to make such a diagnosis without tests etc. When i went back to the office with the medications (some of which were injections i had to give myself at home) i tried to speak to him to get more info about what he said i had - his reply "i know what im talking about and this is serious" so with that i began medicating myself...i decided to reach out to some friends of mine who are RN's and MD's - when i explained what happened they were shocked and advised me to go to an ER ASAP to confirm i needed those medications as they are SUPER dangerous (especially with someone who has stomach problems - which i told Dr Kaminski about). Turns out after the ER visit and a follow up with a specialist I was completely mis diagnosed and every doctor i saw in the ER and the specialist asked me what kind of "quack" would do such a thing! Oh let me mention that with the meds i was on i was going to need weekly visits to his office for blood work etc so everyone assumes this was his way to possibly make money??? hmmmm anyway _ STAY AWAY FROM THIS POOR EXCUSE FOR A DOCTOR!!! oh by the way - after some research turns out this guy hasnt been board certified since 2008 or something like that??? just sayin..... read more

The care was insensitive and inconsistent not to mention that I constantly felt like they were scamming for my $$. They insisted they couldn't share any results of my tests with me without me coming into the office and paying them. Unbelievable. I never thought doctors could set up an office that's basically a scam, but these guys have done it. read more

Amazing experience. And, didn't charge my insurance company an "arm and a leg" - the main reason our healthcare is corrupt in the US.

I agree with half of this forum, he is a little of a "quack." But he's a friendly "quack," and in my opinion a professional "quack." I went in with tonsils the size of golf balls, not being able to eat or talk without wincing in pain. And after his prescription I'm sitting here 12 hours later feeling 100 percent better. No false recommendations or "extra tests." The whole process was seamless and he was a caring doctor. In my opinion at least. read more

Can't speak much to his medical skills yet, but he has great bedside manner. No hint of forced kindness, burnout or condescension.

i can see why the reviews are weird. this guy is kinda nutty, but then who isn't. i found him pretty straightforward and honest. he listened to me and gave his recommendation fairly. he ordered a bunch of tests, but asked me first. i'll report back when i get the results. he was a little mean to his employee while i was there but had nothing to do with me. overall i felt he was a good doctor. read more

The doctor is great and friendly, his staff is not so great, it takes forever to get a prescription written and the front desk lady didn't know what an epipen was... Overall they're fine and nice but if you need a prescription order it 4 days in advance. They're open from 9am-1pm on Saturdays though which is really nice if you have a full time job seeing as they're open from 11am-6pm on weekdays. read more

I was pretty surprised to hear that people think he is overmedicating and nonchalantly giving diagnoses. I have been going to him for years and I have pretty high standards for bedside manner and knowledge. I am skeptical of doctors and do not like when they dont listen to me. I never felt that way w/ him. He always took the time to ask me a bunch of questions and explained things very clearly and thoroughly. The reason his staff may seem unfriendly is because English is not their first language. They still serve largely the Polish community of Greenpoint and therefore all of their staff speaks Polish. I have never been misdiagnosed or overmedicated. In fact I would say he is rather conservative w/ that stuff. read more

Best doctor. Went to Beth Israel on n7 and they told me I had a viral infection.. One week later was still feeling awful so went to Dr. Kaminski and found out I had pneumonia. He was amazing, knowledgable, and gave me all the drugs I needed to get better! Totally recommend!! read more

Dr Kaminsky refused to see my husband when I told him I thought he had chickenpox. He was so afraid of him coming in that he called him five times and then texted him to cancel his visit. What kind of doctor refuses a sick patient?? This place looks like a hole-in-the-wall. I would not recommend this doctor nor office. Close this joint before anyone else ill gets a bad treatment ! read more

I just went here for the first time a week ago and i had a very pleasant experience. I do not have health insurance and i felt his costs wee more then fair and he was very accommodating to me and my needs. i would recommend this Dr. to anyone looking for a family doctor. read more

Do not go here unless you don't mind putting your health at serious risk. He diagnoses almost everyone with asthma. Why? Si he can get you in ine regular basis for breathing treatments. I went aling with this because I didn't know any better, until a pulmonologist told me not only do I not have it, but the medication prescribed to me was not for asthma anyway. He says he runs tesys that he has nit run. I know because I got a copy of the bloodwork. He charged my insurance for tests and treatments that were not done. He said I needed weekly injections (again, get you in the office just to make $$). My specialist found out and put a stop to it as this could have had serious consequences had I continued. He also prescribes antidepressents in lieu of being able to diagnosis an actual physical illness. If you don't get better, ibviously you are 'depressed.' A friend's husband went here and Dr. Kaminski told him he had symptoms he didn't have and argued with him rather than listen to the patient (same thing happened to me). He insisted my friend has GERD and depressikn. No, he has Crohn's disease. I could.go on and on. He has been taking advantage of a population who don't have access to other neighborhood doctors, and of people who don't realize that not only are they being musdiagnosed but sometimes dangerously so. I mean, he's the doctor and is supposed to know these things, right? Thankfully Beth Israel is opening an office here so people can avoud this quack. read more
