"This office made false statements, three times. I directly asked if the doctor i was scheduled to see, 1st visit, was in network with my insurance. They assured me, 3 times. It turned out a flat lie. So i was billed a large sum as out-of network visit. They billed me for 60 min doctor exam. It was, in fact, 15 min. Shamelessly overcharged "

"Charged extra non covered charges even though had just said I'd owe my regular co insurance. When I asked to not pay these non covered charges one time given I was not notified of them, I was sent a bill of hundreds of dollars for disputing the charge."

"For two years, my grandfather battled with CRPS until I found the Rheumatology Therapeutics Medical Center online. Surprisingly, it had great reviews, so we decided to try it. Now, eight months later, he is doing splendidly. Thank you, Dr. Boris Ratiner."

"Before visiting Rheumatology Therapeutics Medical Center, I suffered from myofascial pain, which led to frustration because I could not concentrate on work or anything else properly. However, my myofascial pain has decreased thanks to Dr. Boris Ratiner's treatment."

"After I fell and injured my elbow a few days ago, my doctor recommended that I go to physical therapy. Dr. Boris Ratiner from the Rheumatology Therapeutics Medical Center helped me with the treatments, and now my pain is much better, and I can move my arm again."

"While I like the doctors at this office, the girls at the front desk are very unfriendly. They bark orders and one of them in particular argues about everything. If you call to get an appointment or discuss insurance, she argues. If you try to diffuse the argument, she puts you on hold and never comes back. When I used to work for doctors, we would never treat our patients like this. Too bad that the doctors are not aware of this because it makes you not want to come here when you are in pain."

"There are a lot of instances in life where you have a bad experience with a medical receptionist or someone in the medical front office where you just decide to let it go and not write a review but in this case upon my husband’s urging I’m writing this review for all of the potential patients of Dr. Boris that decided to seek a rheumatologist elsewhere. Dr. Boris was highly recommended by my cardiologist so as directed I called in to make my very first appointment. The call was answered by a young woman ikea who was inept with her lack of information, her lack of a welcoming spirit and or enthusiasm for what she does and told me that she was unable to schedule me at this time and that her colleague Carolina was alone and would call me back. I answered ok, and kindly asked if she would be calling me back today or if it would be tomorrow. Her answer was “ I don’t know”. I asked what time they closed and she said 5:30pm and since it was already in the afternoon I asked if she minded if ...
I called back in an hour to follow up and she seemed irradiated with my request. I explained that I have a daughter here at the house and I just wanted to give it one more try to schedule as I didn’t have any idea of when the call back would be! A few hours later I received an abrasive call from office scheduler Carolina with a bullying attitude and saying that I was rude to her assistant Ikea. I truly felt as though this is Not how I should be received and treated as a potential new patient by a front desk staff!!!! With the thousands of dollars that I pay for PPO insurance I made the decision to let Carolina know that this is just so unprofessional and that I would be seeking another Rheumatologist elsewhere. I wonder if Dr. Boris knows that is how his staff behaves? I have informed my cardiologist of how I was treated and to not refer others over in the future. I truly believe some front desk staff lack empathy and just feel that they have the power to treat new patients and existing patients in a horrible manner. This is the case here! This staff should at least be monitored so that Doctors can see first hand how these bullies are behaving. "

"In 2020, Dr. Ratiner prescribed six iron infusions in his office for my wife after doing a blood test that showed that she had low blood iron. She died after getting four infusions. She was 92 years old and frail, and it is known that frail people can be killed by any medical procedure. The most accurate test for iron deficiency is ferritin, not blood iron, which can be misleading. Medical books say that iron therapy should not be done until the doctor has made a search for the cause of the low blood. Dr. Ratiner made no such search. He also told me that, since she was on hospice, Medicare would not pay for the infusions, so I would have to pay upfront for the six infusions, which I did. I found out later that he had billed Medicare and been paid by them. I then asked him to refund the over payment, but he refused. "

"The doctors seem to have more respect for the clients than the low toll employees. The fat long haired Hispanic woman sits in front in left chair has a bad attitude and just argues with the client about everything. She also sits there gossiping about the clients and going on a tangent about her promise ring she got. In the back there is another mean unfriendly overweight long black hair Hispanic woman who acts like she is an officer holding you. Why allow your employees to be like this with clients? I would not recommend anyone going to this business, this is what you will encounter before and after seeing the doctor."

"Thanks, doc, for your dedicated care of my mom. She was in lots of pain due to arthritis, but she is now okay and can walk without aid."

"I am a 2nd generation Russian, and while my English is good, my parents who live with me are not fluent. Luckily, Dr Ratiner understands Russian and can easily communicate with my dad. We have been taking him there for arthritis treatment, and he loves it."

"I was self-medicating joint pain for 6-months, but the problem kept getting worse. A close friend told me to seek help from Dr. Ratiner, and it was a lifesaving decision. Dr. Ratiner diagnosed me with gout and put me on treatment right away. He kept tabs on me until I got better. He is the one that saved my life."
  • March 8, 2021
"Dr. Ratiner is one of the most passionate doctors I know. Despite his quite noticeably busy schedule, he followed up on my case and would regularly call just to make sure that I was getting better. I felt like I had someone by my side who cared about me and the pain I was going through. I believe this helped me heal faster."
  • March 7, 2021
"This my second time getting help from Dr. Ratiner, and I am happy with the service. I have been battling with arthritis for a while, and compared to other doctors that have treated Me, I have got much better since I started receiving treatment from him. I am grateful."
  • March 6, 2021
"He is friendly and has in-depth knowledge of joint issues. For the past 6-months, he has been treating my ageing grandma of knee-joint problems, and we have noted a significant improvement. Grandma can walk for longer distances than she could do pre-treatment."

"I was referred to Dr. Ratiner by a doctor friend of mine, and it was an excellent recommendation. Since I started my treatment sessions with him, my joint pain problem is gone. Be blessed, doc."
  • March 4, 2021
"For anyone dealing with arthritis or other joint issues, I would strongly recommend you book an appointment with Dr Ratiner. He has been treating me for the past month, and I always feel comfortable around him. His communication skills are top-notch, and I have learned a lot from him on the lifestyle changes to make for a better quality of life post-treatment."

"My grandpa had rheumatoid arthritis and was treated at the Rheumatology Therapeutics Medical Center. I would like to thank all the medics that helped him. Special thanks to Dr. Ratiner. He was deeply involved in grandpa’s treatment until grandpa could walk again. Thanks, and keep up the excellent work."
