    If I ever have surgery again, I will definitely go with Dr. K. His team is amazing! They were very professional, caring, and always ready to help with any little thing. Also, I loved the patient resources online. Thanks Dr. K. :)

    I went to Dr. Karzel for a injury to my shoulder. He is very informative and explains treatment options. He spends time with you and answers any questions. He performed shoulder arthoscopy surgery and repaired a torn rotator cuff. Dr. Karzel explained exactly what he was going to do and I never felt like he was rushing thru the exam to get to the next patient. My surgery went well and I am on the road to recovery. I would highly recommend Dr Karzel.

    He is an amazing doctor.

    My meniscus knee surgery was amazing. There was next to no swelling, there was no pain, so as a result, I didn't need to take any pain medication. Instead of icing the knee post surgery, he had a refrigerated cooling machine delivered that attached to a velcro- type wrap-around sleeve. I found this much more convenient than changing iced filled bags continually, and it made it easier to shift positions by not having to re-position an ice pack every time I moved. I highly recommend Dr. Karzel

    This is my second surgery performed by Dr. Karzel. The first was about 20 months ago on my left shoulder. This one was on the right shoulder. In both cases I had little pain after the first day or so. The left arm is still functioning well and I have had few problems with it. I am right handed,so it hadn't been relied upon until the right shoulder was operated on. I am using it much more right now and am very happy with the results other than a general lack of coordination which has always been

    Very comprehensive on his exams. He spends a lot of time with you. Answers all your questions. Very personable. I would definitely go back to him.

    Dr Karzel is the best surgeon and for that matter physician experience I have ever had ( and I am a registered nurse). Firstly, he is the kindest, most considerate physician I have ever had treatment from. He took great time to review my MRI slice by slice, and carefully explain the unusual condition I had, which was a knee tumor. Secondly, his confidence and great knowledge put any anxieties I had about my condition and upcoming surgery to rest. He even videoed and narrated my surgery for me!

    Doctor Karzel was able to properly diagnose me after seeing other doctors who misdiagnosed me. The surgery was a success and I could not be happier.

    in Pearblossom, CA |
    Extremely professional, personable and confidence inspiring. His office staff is equally professional, courteous and personable. Best experience I've ever had with a medical professional and staff.
    in North Hollywood, CA |
    One of the most competent and friendly doctors I've ever met. He performed arthroscopic surgery on my right shoulder in 2004 to repair a torn labrum and rotator cuff. Recovery and rehab were just as he forecast, and I returned to full activity within a year with nearly 100% range of motion. He recently repaired a torn meniscus in my right knee, and again did an outstanding job. Just a great doctor and a great surgeon, working at the peak of his powers. I highly recommend him.
    Santa Clarita, CA |
    Dr. Karzel was personable, yet professional. He was very thorough in his explanation of my injury and treatment, making sure I understood all of my options. Dr. Karzel also took as much time as needed to address any concerns and/or questions. In addition, he included my spouse in these conversations to ensure she understood what was needed to assist me in my recovery.

    I have had the privilege of working with Dr. Karzel as well as being his patient . . . Twice! He and his team are the best there is. From the moment he meets you until your last checkup, you feel he truly cares about you. He is a very educated surgeon and it shows. He has a great way of explaining everything and makes you feel very comfortable.

    I was nervous at first everyone said shoulder surgery is the most painful surgery you can have, but I had no choice, I was in constant pain all the time anyway. So I tell this, if you EVER need shoulder surgery you must go to Dr. Karzel. He is the best in his chosen profession, I am so blessed I had a wonderful Dr. that referred me to such an excellent surgeon. He is kind, caring and very concerned about patients plus the the fact it didn't hurt as much as everyone said, which was nice.
