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.

great doctor
Dr. Peng is a great doctor. He listens to you and is very knowledgeable. He is not a doctor that will keep pumping you with different meds. If the medication you are on is working; he will not switch it up just because there maybe something new on the market.

I would like to start with a quote from Sir William Osler that said, “The good physician treats the disease; the great physician treats the patient who has the disease. This note is for anyone who is desperately searching for a good Rheumatologist who will take time, listen, and ask questions to get to the bottom of your problem. Even if it is necessary to check with your other physicians to see if your problems are connected to other issues, you might have and treat you with advanced treatment available accordingly. Without exaggeration, Dr. Justin Peng is one of the best doctors I have ever had. He brought my disease under control and gave me the chance to live a better life! Heartfelt thanks for this invaluable opportunity. Sue Ghandchilar

I made an appointment on line 5 weeks ago for an appointment. I filled out all the patient info on line in advance. I was called two days before my appointment to say they didn't take my insurance or new patients! I was so frustrated; I had waited 5 weeks to be cancelled at the last minute! Now I have to start the process all over with another doctor.

Dr. Peng took his time to listen to me and he asked me questions regarding my health. He reached out to one of my other doctors to get more information. Dr. Peng called me before the end of the day to share the outcome of what he discussed with my other my other doctor. He is so responsive a d attentive. His follow up is outstanding.

Another Great Visit
I arrived about 15 minutes before my appointment time. Nonetheless, within 2-3 minutes a health care staff member began the visit's treatment. Each member of the staff treated us, my wife and me, with respect and care. After reviewing the data gathered by his staff, Dr. Peng asked a number of questions, In addition to a physical exam, he patiently listened to my answers to review my progress since my last visit, six months ago. He provided his conclusions in an understandable manner and offered advice and a course of treatment. It is refreshing when a physician listens to his patients, giving them sufficient time to describe their conditions and concerns.Thank you, Dr. Peng

Highly recommend this Rheumatologist
Dr. Peng is a rare combination--an expert in Rheumatology and a personable and kind person. When I came to him on referral from my primary care physician, I was in terrible pain--I could hardly function. Dr. Peng carefully diagnosed my problems and formulated a patient care plan. I have done my part, following his guidance on exercise and medications, and as a result I continue to be pain free and extremely happy. I couldn't be happier to be under his care.

Dr. Peng is the best! He is thorough, careful, informative and does not rush unnecessarily into treatment, if he feels that watching it over time would be equally helpful.

Dr. Peng is great! He is encouraging and truthful and I appreciate having him as my doctor as I continue Prolia treatments for osteoporosis. He was key in helping me determine that Prolia was the best treatment for me after my primary care doctor took me off of Fosamax due to problems it was causing. I'm grateful to be working with him!

The doctor seemed good. This review is about billing, not sure if that is on him but maybe he's complicit. I was there for a 45 min office visit (seeing doc for maybe 15-20 min of that time max). Had x-rays of my foot and hand. Received a bill after insurance of of $862! I had a similar visit with my foot doctor with x-rays (another specialist) and HIS BILL WAS $97.00. Something is rotten in the state of Denmark as they say. Dr. Peng's consultation fee for the 15-20 min was $585, insurance knocked it down to $533. X-rays at my foot doctor were around $65 of which I paid half. X-rays with Dr. Peng were $180 of which I paid $165. I called the office and they said it's not their fault the insurance company allowed the price of $533 and other prices (Oh, Really - you charged them that much). No reason that any office visit/consultation for any doctor should be that much for that amount of time.
