I generally have a distrust of doctors. I was anxious and insecure with my first visit and couldn't describe my symptoms adequately. That's just me! However, Dr Tambar comes across as a caring doctor who can potentially help a complicated person like myself. He takes a lot of time to answer your questions. He was kind to my husband and answered his questions as well. Jasmine at the front desk was courteous and friendly the moment I walked in.

I'm a recovering distance runner and have struggled for the last few years with a weak and broken knee and finally feel like I am back on track. Best of all Dr Tambar and his team delivered high quality care and commitement to detail that helped me feel like I was in the best hands. Don't give up, give this a shot. I have no regrets!

I know I am in great hands with Dr. Tambar and his staff at Chicago Arthritis. They truly care about me as a patient and have been instrumental in treating my arthritis with diagnosis, treatment, and being a shoulder to lean on. My journey with arthritis has had its twists and turns so I’m glad to have switched rheumatologists to Chicago Arthritis because they have supported me throughout it. When I had a really bad flare up, everyone was sympathetic and worked diligently to get me back on a treatment plan. When I had some higher numbers in some blood work, they explained it to me and we ran further diagnosis to rule out any concerns. When I had some insurance billing issues, they helped me solve the issues and expedited getting my medicine. If you are just beginning your journey or are looking for new paths in dealing with your issues, Chicago Arthritis is the place I would send you, my friends, and my friend family.

I have had a great experience with Dr. Tanbar and the entire staff: friendly, helpful and supportive. They really helped me when my pain level increased and my overall situation worsened. I have my (first?) procedure the first part of June and I fully expect the staff will provide this same good service and personal attention.

I see a lot of investors go into research everyday on what to invest in. I was like that few months back. completely confused and don't know which direction to go in terms of investment. i came across the review online that changed my life. I decided to invest my first $2000 with Mr. Ethan Payne who helped me trade and made a profit of $10,000 Within a few days. from then on, the rest is history. His great skills in Forex and Crypto trading made good profits for so many in their trading account. I was amazed how many Investors wrote good comments about him. I earned a very good profit and made my withdrawal successfully and directly to my bank account. I'm on my third investment with him now and I am very happy to have met Mr. Ethan. I now earn good profits working at home, all thanks to him. I know this is inappropriate but this is my little way of showing gratitude and appreciation to him. If you wish to invest, Contact him now Via WhatsApp: +1 (256) 215-1536 E-mail:ethanpayne700@gmail.com

Everyone at Chicago Arthritis were great - very professional and very friendly. The PA's interview was thorough. Dr. Tambar was very pleasant and approachable - easy to discuss my issue with. He was thorough too - asked pertinent questions, and made sure I understood that the tests he was ordering would help with diagnosing my issue. He did an Ultra Sound on my wrist in the examining room, and he took the time to explain to me what we were seeing. In the followup visit, he explained what the test results indicated, and recommended treatment for my condition. At no time did I feel that he was in a rush to see the next patient, like I often felt with the many specialists I saw for my condition. I am extremely impressed by the service I received on both my visits. I highly recommend Dr. Tambar.

I had my first TeleHealth Zoom Appt with Dr. Tambar and it was a very positive experience. His staff was very professional, helpful and caring. They obtained all of my medical history records needed for my appointment, and ensured everything was correct prior to my appointment; it appear to be a very seamless process/effort despite living miles away in another state. Dr. Tambar was very thorough, he listened to all of my concerns and answered all of my questions regarding my condition, and the treatment I am seeking. I'm very hopeful now that Dr. Tambar will be providing me with his medical expertise🙏😊🙏

Dr Tambar and NP Leah are very knowledgeable. Dr Tambar worked promptly in our first session to get the lab results and ultrasounds necessary to verify my RA. Regular follow ups were great to update my treatment and now my current treatment has eliminated my joint pain, swelling, and stiffness. It’s definitely scary to live with RA and I had to be patient to find the right treatment but they did their best to be your advocates and aggressively treat. The only negative is that the billing is archaic. Bills are sent via paper mail. Definitely need to track claims with your insurance for all charges…

I had a wonderful experience with the Chicago Arthritis Regennex center. It was beyond wonderful!! I came in with terrible hip pain and in few short weeks I’m feeling so good I’m pinching myself and can’t believe how great I’m feeling!! From the initial telemedicine visit, Dr Tambar and Devi the practice manager seem to settle any of my anxieties. The entire team, Dr, Tambar, Devi, Leah, the PA and phlebotomists were so professional and perfectionists ensuring to get the procedures done correctly. I’m a Physical Therapist owning my own practice. The last 14 years we focused on patients with chronic pain. The regenerative medicine practiced at the Chicago Arthritis Regeneration Center is ‘state of the art’ and the missing link in the treatment of patients with chronic pain. God bless you all!!!

If I could give more than five stars, I would! I have been a patient of Dr. Tambar for many years. I have always been impressed with the care that he and his team have provided from day one. From diagnosis to ongoing treatment, the personalized care that I have received is above and beyond any practitioner that I have ever experienced. From the front desk, the practice administrator, the nursing staff, PA Leah Brown, and Dr. Tambar, all have been exceptional. Dr. Tambar goes out of his way to make sure all your questions are answered and that you understand your treatment and options. His personal touch and bedside manner are stellar. In addition to the care and treatment that Dr. Tambar provides, I have been impressed with his ongoing outreach and education through his social media presence on YouTube, Facebook, Twitter, TikTok, and Instagram. I highly recommend Dr. Tambar and the team at Chicago Arthritis and Regenerative Medicine!

Dr. Tambar and his team never fail to dilver excellence service. I’ve had many procedures done with him due to many injuries. I have had mild to severe partial tears in my neck, shoulder, knees, and this week I’ll be taking care of my lower back, bicep along with the tricep. I know I’m a broken down car, but I’ll pick this regenerative medicine over surgery any day of the month. I would highly recommended going in for a consultation if your suffering from any degenerative condition. Dr. Tambar thank you again for your outstanding work.

I couldn't be more pleased with the experience I had at Chicago Arthritis. Not only was the care team very attentive to my needs, but my experience with Dr. Tambar was one of the best I've ever had. Dr. Tambar took the time to fully understand and assess my condition, very candidly explained my treatment options, and very transparent about my expected outcomes with treatment and short/ long term implications of abstaining from treatment. I was assessed for problems with both of my hands and, after evaluating the conditions of the nerves in both of my hands, Dr. Tambar empathetically informed me that my right hand would likely require surgical intervention but that my left hand was a great candidate for a Regenexx procedure. I opted to have both hands treated and I'm delighted to say that my left hand (the one that was given a decent candidacy rating) responded very well to treatment, and my right hand resulted in almost exactly what Dr. Tambar advised me of before treatment. Unfortunately, my right hand had digressed to the point that surgical intervention was necessary (just as Dr. Tambar informed me), but I couldn't be happier with the results I experienced in my left hand. Thanks to Dr. Tambar, I was able to avoid a second surgery and got back to weight lifting and typing far faster than I could have and with considerably less pain and downtime than surgery would have yielded. I strongly advise that anyone looking for non-surgical options for treatment of orthopedic conditions see Dr. Tambar; I can personally attest that he will give you a straightforward assessment of your condition and treatment options and may help you avoid surgery!

Dr. Tambar and Physicians Asst. Leah have been doing a wonderful job for me for many years. They drained fluid from my knee on the same day I called. It was a world of difference that a doctor from IBJI never even suggested. I wish that I would have called Dr. Tambar over a month ago when this started. Hopefully this painful month is over. Stick with the doctors you know do a good job. Thanks you guys!

I have sought medical expertise three times now at Chicago Arthritis & Regenerative Medicine, the first time to address an arthritic and swollen ankle, the second time to address a spreading swollen calf, and the third time to seek blood test results for a potential cause. In all instances , not only was the desk staff, technicians and therapists very warm, welcoming and professional but the founding Rheumatologist Dr. Siddharth Tambar proved attentive, caring, discerning, and ultimately helpful in healing my ailment. That is why I am rating this medical practice the highest stars.

I have been with Dr. Tambar and Chicago Arthritis since I was diagnosed with RA 4 years ago. Dr. Tambar and his staff have been a Godsend! He listens to you when you talk, not typing on the computer! When the pandemic began, I sent many frantic e-mails to his PA, Leah, and she answered me right away. The office staff is ALWAYS pleasant and willing to help. They are always willing to go the extra mile when working with the insurance company or other members of my care team. 5 stars!

The entire experience was great from start to finish Dr. Tambar is extremely professional , friendly well educated and number one in the nation and the staff is friendly/ accommodating and went above & beyond my expectations . I’ve researched for over a year before I had my treatment done (lower lumbar ) the treatment they offer at Chicago Arthritis is truly one of a kind & custom per situation. There are many scams out there so please be careful & follow the science, results of patients and remember there treatment is a natural cure not a band-Aid epidural injection. I obtained some of the information from Regenexx company the original creature of the generative treatments , they started in 2005 in Phoenix Arizona. As the company perfected it’s treatment and started to grow, they certified other physicians throughout the nation. In the Chicago land area there’s only one certified Regenexx trained location (Chicago Arthritis). My first round of treatment had wonderful results & no longer taking my Vicodin/ naprosyn or any other pain meds , my pain level is currently around a 3-4 out of ten , so I’m probably going in for one more procedure which should put me at a zero . I would definitely recommend the Regenexx treatment depending on were your located the treatment isn’t typically covered by the insurance , so I guess it’s a personal decision although what’s the Value of living pain free ?

I have osteoarthritis in my shoulder and the treatment I received from Dr. Tambar and his staff is one of the best medical experiences of my life. They are prompt, courteous and knowleable. I saw Dr. Tambar multiple times and I rarely had to wait longer than 2 or 3 minutes in the waiting room. Dr. Tambar not only took the time to explain my condition and treatments in detail to me, he is also a good listener and paid attention when I described my symptoms. (Listening can be a rare quality for some physicians and specialists.) I could not be more satisified with the entire process, from start to finish. I can recommend Dr. Tambar without reservation.
