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. Karzel was very patient with me and my wife and answered all the questions and concerned that we had. He took time with us and explained everything he's going to do before the surgery and what to expect.

Dr. Karzel is Amazing!
Dr. Karzel is a very personable, caring and skilled surgeon who loves what he does. He is great at explaining the process of your procedure and even does drawings to help explain. He shares all imagery from X-ray, mri, and post op images and recordings. He made me feel comfortable and informed. He is a professional and well respected and admire red by not only patients but other doctors and surgeons. My rotator cuff repair surgery went smooth and without complications. I highly recommend Dr. Karzel.

Knee surgery
Dr. Karzel did a really great job with my knee surgery. He did a great job explaining everything he was going to do and the get well loop was a great resource to help me after the surgery. If I or anyone I know needs help with a knee injury. I would send them to Dr. Karzel.

Dr. Karzel
Dr. Karzel and his team exceeded my expectations in all aspects of care. In pre surgery appointments, in surgery, and post surgery he was always extremely respectful and caring. Having a complex surgery, Dr. Karzel told me everything that might happen, and what he was going to do about it. Not to mention doing a phenomenal job on the surgery itself. I will always be going to Dr. Karzel for my knee injuries.

Excellent Doctor
Dr. Karzel recommended a Meniscal Root Repair and possible ACL replacement. He talked through all the options there were for me, and gave me choices and recommended research. The outcome could not be better. The team in the office and the surgical center are just as fabulous - great at communicating, and putting at ease. All around, a really good experience. I highly recommend Dr. Karzel.

He explains the procedure well and every visit he checks you thoroughly. On the day of the procedure his staff was also thorough. The surgery went on smoothly. They also have an app that would constantly follow-up on you and when you have questions they answer you right away.
