I’m so grateful for Diana Szilvasi who truly listens and provides consistent, compassionate support at every visit along with Sherry at every infusion. Their dedication and kindness have made a real difference in my health and peace of mind.

1.My interaction with Dr Tierra Anderson was very good as she has a way of putting you at ease. I was very stressed, and talking to her felt like I could manage this problem without getting overly stressed.Thank you DrAnderson2.My experience at the front desk wasn't great. The lady informed me after I came out that i had overshot the time. I was aghast. Firstly when you are meeting the doctor the first time, she will need to know my history and go over my test results to give a treatment plan.3.Today I spoke to Nino B in the billing department as there was certain discrepancies in what I was billed. He went over my insurance and assured me that the extra charges billed will be corrected in my next appointment and i don't have to pay for that.Was very nice to speak to and knew his job. Thanks Nino for your help.3.3.

Just finished up a year long gout study here. The staff were nice and always explained every step very well. Dr. Nirotma Tripathi looked after me most of the time and is attentive and very kind.

First visit saw Dr. Putz. He is Kind, a great listener, and explained everything well. Asked questions on arthritic kneess but also the neuropathy in feet legs. Blood tests to look at autoimmune markers. Amir was my greeter, what a fun and sweet guy. He even helped me with check in forms on my phone. Felecia took blood and she was so very kind and fun to get to know. She was very patient with a new girl she was training. The receptionist was also patient and helpful. At 77 we need help with filling out forms on our phone. I couldnt get it to accept info on my computer prior to my visit. This was a bit tricky so I think paper forms would help those of us who are not tech savvy please. The appmt was 9:30 and there was a 40 minute wait..they apologized.Busy place but comfortable and welcoming.

Had an excellent experience with staff and Dr. Dada. Highly recommend from a clinical/medical perspective. Biggest issue that is still unresolved is their patient portal. After multiple attempts with the app being very glitchy, I tried to access the portal on my computer and it continually locked at a certain point. Website says you can get technical assistance in the portal but since I couldn't access it there was no tech assistance number or link or FAQ page. Highly frustrated, I contacted the office and a very accommodating staff member is still trying to assist me.At the visit, I wanted a print out of the visit info and was told I needed to get it through the portal. When I told the MA about the portal issue, she suggested I try again the next day. So technology issues are only reason for 4 star review.

I have been going to Overlake Arthritis & Osteoporosis Center for over a year now. I can't tell you what a wonderful doctor I landed upon with Dr. Diana Szilvasi! She is so warm and enduring. She cares about you as a person and so very through with your needs. She is so easy to talk to and share your concerns and she definitely wants the BEST for her patients. She herself is patient and a problem solver if something isn't working. I couldn't be happier with my care from her. She is an angel from above!

Diana always takes the time to answer questions and give suggestions on how to improve my bone density. Ruth gave me my shot of Prolia shot. She is easy to talk to and has a great personality.

At 71 osteoporosis was my first medical condition I had to face so was concerned and anxious. After I met with Diana I was completely put at ease and understood where I am and where I am headed. She was understanding calm and so knowledgeable. She took as mich time as needed to answer all my questions and explained in as much detail as I needed. I would highly recommend putting my care in the clinics care

After a few years of care with another rheumatologist I found Dr. Dada and it was life changing! Working with Christopher to make a treatment plan has been incredible. After a few months and switching meds I feel like I am finally on the way to pain free days! You won’t regret making the change to Overlake Arthritis and Osteoarthritis Center!

The staff is very courteous and helpful. Constantina was very good at making me comfortable for the DEXA Scan and took time to explain everything. Tierra also helped me understand the results of my scan.
