Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr. Tambar injected PRP to my wife's aching jaw. She is in almost no pain now. Life changing!

Horrible! GET A 2nd OPINION, if you’ve already seen him! In April 2019, Tambar falsely diagnosed me with RA and suggested medication (Methotrexate) which is used for Cancer patients.... “I’m prescribing you, Methotrexate, you may lose your hair and experience ...... but I’ll see you in 3 months”. WOW, RIGHT?!!! Immediately, I secured a 2nd opinion. My lab work also didn’t hint at the #’s of RA. This week, Sept 2020, I got a call from his medical office following up on “my condition” (this was after I made it perfectly clear in May 2019 my disgust and concern for a false Medical diagnosis), when I reiterated (Still NO APOLOGY) no interest in them contacting me. The patient representative aggressively disconnected me. THE AUDACITY!! Horrible customer service and a physician who falsely diagnosed me; a medical outcome that could have changed my life if I didn’t have the necessary resources. Not to mention, when I sought an additional life policy, I was immediately flagged as a risk.

Well again I have just left Dr. Tambar’s Office. I’m afraid I’m going to have to create a six-star review category. Again, he took me out of excruciating pain with great ease. The staff was again outstanding, courteous, and professional. Davy snuck me in on an emergency basis, and Judy knows her stuff like an ace. I highly recommend Dr. Tambar, and wouldn’t consider going elsewhere. I was in such pain I couldn’t sleep or walk. All fixed in a flash. Dr. Tambar makes it look simple, and once again saved me and removed me from pain. He is an A-Lister. I remain very grateful. Sincerely, Dennis Doherty.

Dr. Tambar met my expectations and more. He was kind, friendly, thorough, and truly cares about giving his patients a good experience. Several times I have left doctors feeling alone and helpless, I did not feel that way after leaving my appointment.

Dr Tambar earns 5 out of 5 stars because of his bedside manner, ultrasound imaging skill, depth of knowledge regarding soft tissues/bone and the revolutionary treatment methods that he provides. Before experiencing an orthpaedic surgery, in fact before allowing steroid injections, go here!

The RA in my hand was quickly and thoroughly diagnosed by Dr. Tambar. My condition never got very complicated so I cannot comment about his ability on more complex cases. Unfortunately his office is moving from Lakeview to Fulton Market which is not a convenient location for me. I will be seeking another rheumatologist.

WHAT A WASTE OF TIME! If you are genuinely concerned about blood test results showing abnormal RNA/ANA tests. PLEASE DON'T GO SEE THIS CHILD OF A "DOCTOR". DR. TAMBAR GO BACK TO SCHOOL!!!! To be fully honest Siddharth Tambar, don't feel comfortable calling him a doctor, is just another IL based doctor that is so scared of malpractice that he plays the "fun" game of passing the buck and sending you to another specialist that will do the same thing and end up in a endless loop with never getting

I attempted to make an appointment for the office and the staff informed me that the office does not take Medicare of Arizona. I attempted to explain to them that Medicare is not a state program, it is a federal program. They would not listen to what I had to say. The office staff needs to be educated about Medicare, customer service, and listening to what patients are trying to tell them.

Very expensive visit with very few results. Office visit is 350.00 before insurance. Had a lot of trouble getting Dr. Tambar's office to communicate with my doctor's office and I ended up having to be a go-between - no transfer of records. Physician's Assistant was very brusque and impersonal. Also, a list of patient names and DOBs was left up on the computer screen when I was shown into the room to wait for Dr. Tambar.

My experience with Dr. Tambar has been excellent. Very caring and knowledgeable physician. Sometimes Drs. can be intimidating but Dr. Tambar is far off from being one. I like the fact that he uses very up to date technology during visits and is always concerned of my well being and always making sure my condition is stable. He is very patient and always takes time to listen and gives the best advice and opinions. I would definitely recommend him and his facility to friends and family.
