I have been a musician all of my life. I need my hands. Dr. Mazur treated me in the most effective and least invasive way possible. This guy asks questions and listens. It's no surprise to learn that he has been the go-to guy for some of the best players on the planet. read more

Doctor is awesome. Office got a new manager and there has been a tremendous change for the better. Congratulations!

Dr. Mazur is patient, kind, listens, careful not to cause pain during the exam, doesn't rush you through your appointment. Now that he's part of Sutter, it remains to be seen if he will continue to be as accessible to his patients. His office staff is great, as are the PT people on his team. He tries to avoid surgery unless it's the best option for his patient read more

Great doctor, but the front office has real issues. Phones don't get answered and messages don't get responded to. I am being forced to look for another doctor. read more

Dr. Mazer's technical skills are superb. His communication skills aren't. I had my finger amputated. He did not go over all the pros and cons of the procedure. When I asked about phantom pain he waved it away. After the procedure he said things could have gone bad. When I asked what that would be, he wouldn't explain or answer. I pointed to the bone sticking up a little at the wrist. I was looking for an educated explanation. All he said was "so"! On the final visit I told him I was experiencing phantom and pain at the site. His only answer was to take mega Tylenol and Advil and go see my MD for an antidepressant. She sent me to a pain doctor. Why didn't Dr. Mazur do that? He didn't care past the hands on surgery. read more

Fantastic Doctor and grateful for his level of expertise. Many friends and family have worked with him.

I just saw Dr. Mazur today to take a look at my xray results. I have nothing but excellent things to say about the doctor, the staff and the facility. I was greeted by the staff at the front desk and didn't even have to wait in line. I showed up early, so I waited about 15 to 20 minutes in the waiting area. It seems like this place is always busy because there weren't that many empty seats, and there's always people walking by to go to this physical therapy area. For how busy it is, I was in and out within an hour. The facility is nice and new! I felt like a hamster navigating through the halls to find the exit out of the building. Rooms are nice. I actually like the lighting in there because it's not one of those older buildings with the harsh fluorescent lighting that makes you feel like you want to put on sunglasses. I met one of his medical assistants, Leigh Ann (sp? sorry, if I butchered it!), and she's really friendly! She typed in my notes as a new patient into the computer. Then, Dr. Mazur walked in and explained to me what happened with my left hand and checked my fingers to assess further pain/problems. Everything went well! No pain. He's very knowledgeable and patient. I highly recommend him and the staff at this place. **TIP: If you're a new patient, go to their website and print/fill out the documents. It saves you some time filling them out in the waiting room. read more

The best hand surgeon in Sonoma County! Very professional and caring

THE BEST upper extremity orthopedic you'll find in the county! Specializes in hand and nerve repair. He fixed my spiral fracture (humerus) - for now I'm typing with one hand, but I'm so relieved and confident about my full recovery with the help of his team (especially Jen, my therapist!) he is awesome!! read more

Dr Mazur is a Great surgeon, he Came highly recommended to me after having a complete distal biceps rupture in my left arm. I am back to normal life thanks to successful surgery and recovery. Thank you! read more

Dr. Mazur is THE BEST surgeons EVER! He's very kind and always takes the time to listen to his patients, as well as explaining every step of the way from diagnosis to, if necessary, surgical procedure and after-care. He really DOES care about what his patients go through with the pain of their injury/condition! Very rare to find that ANYWHERE anymore!!! (Well, maybe when I was a child in the late 60's/70's and earlier...maybe...if you were lucky.) His assistant, Christina, is awesome, too! She's very attentive to his patients' needs and is just easy to talk to. I have had two surgeries performed by Dr. Mazur (first for right shoulder in 2016 and the other for right wrist and finger in 2017). I need more surgery on the other hand and wrist, and won't even consider going to anyone else but Dr. Mazur!! He's all you've read and better! Thank you Dr. Mazur and Christina and the rest of your wonderful staff! Laurie H. read more

ENJOY THE FREE MONEY. read more

Really appreciate the time and effort that Dr. Mazur spent with me addressing all my concerns and answering all my questions relating to my pre surgery visit. And after my 6 week complicated tendon surgery, Dr. Mazur reassured me that my rehab was on track and the postoperative issues I experienced were normal and to be expected at this time. Thank you Dr. Mazur for helping me to successfully complete this journey. read more

I'm a registered nurse I actually enjoyed my visits with this doctor as he is easy to talk to and very genuine. He repaired both my carpal tunnel wrists and later my rotator cuff tear, deformed clavicle and spurs. It's been three and four years and all 3 surgeries had excellent results. Will have him repair my other rotator cuff soon. Highly recommend this doctor. read more

Dr Masur repaired my broken wrist. Dr Masur has always been very professional and makes sure you understand the procedure he will be doing for you. This is the second time I have needed an orthopedic surgeon and I was so happy he was available for me.again . I highly recommend Dr Masur. Dr Masur has always made me feel at ease with both my surgeries. Dr Masur is very easy to talk to, very kind. read more

The best hand/shoulder doc in area. Mazur has done both my shoulders and is great. The 10 to 25 minutes I've had to wait in his office mean nothing to me because I know I'm getting the best. The only bad thing about his being so good is that I had to wait almost two months once for surgery because he is so busy. During my post surgical physical therapy sessions I saw a guy that was doing very similar exercises to the ones I was doing. I asked him what happened to him. He said he had injured his shoulder 6 years before and this was the third repair on it. He said that this time it was finally done right because he had it done by Mazur. When I had initially injured my first shoulder my regular doctor gave me a list of three orthopedics surgeons I could choose from. I checked where they had done their residency. Two did theirs in Cairo, Mazur did his at the Mayo Clinic. Guess who I picked? read more

Dr. Mazur is the best Orthopedic Surgeon ever! His bedside manners are impeccable, he's so sweet and kind, very respectful to his patients, listens to everything you have to say, I just can't say enough about this wonderful doctor and his staff. We moved from Sonoma County almost 2 yrs ago, when I needed hand Surgery done a year ago I never thought twice who I wanted to fix my hand, we traveled 6 hrs one way for Dr. Mazur to do hand Surgery on me, I just had my shoulder fixed as well. Look, were we live there is plenty of capable doctors, BUT, none I would ever trust to touch me. When you have this kind of faith in a doctor like I do, you stay with this doctor always! read more

Dr. Kai Mazur is awesome, amazing ect ect ect... he is a professional and caring Surgeon he was definitely worth the 4 to 5 hours drive to get to him! he really helped with the procedures i had done as far as i am concerned he is #1 in his field!!! and #1 to me. :) read more

I had a painful cyst in the palm of my hand for months that I just dealt with and adjusted my life around, until I visited one of the best doctors ever! Dr. Mazur is one of the most genuine and caring Dr.'s I have ever met. He has a warm and sincere presence. It wasn't until my hand was fixed by him that I realized the quality of my everyday life had been greatly improved. I would highly recommend him and would like to thank him! read more

Dr. Mazur was thorough and thoughtful in his assessment prior to recommending surgery. He explained his rationale and the procedure in detail, listened to my concerns and addressed all questions. Post surgery, his assistants provided excellent care and encouragement and, once again, addressed all concerns. Dr. Mazur's quiet confidence and his expertise are beyond compare. read more

Dr Mazur's Nurse, Christina, is EXCEPTIONAL! Very opersonable and knowledgeable! Really went that extra mile! Dr Mazur is one of the best doctors I have ever encountered. It is unusual to find brilliance and kindness in the same physician, he is truly a rare breed. So thankful to have had such a positive experience! read more

Dr. Mazur is a professional with a wonderful personality. He is super intelligent and fixes us all. I would never go to another hand doctor as long as he is still around. The entire office staff is professional and kind. read more

I have been a patient of Dr Kai for some time now, different issues. Dr. Mazur prepared me for everything I experienced in post surgery and recovery and the scar is all but gone. There were no surprises at all. His bedside manner is comparable to none and I would highly recommend him for any type of hand or arm surgery. One of the best in the business. read more

Dr. Mazur is the best orthopedic hand specialist on the West Coast. I was diagnosed with Dupuytren's Contracture in 2000 and told the only treatment was surgical. Dr. Mazur recognized my condition immediately, explained the treatment options and performed needle aponeurotomy and released the contracture in my right ring finger on the first visit. He and his staff are the absolute best. Kudos to a great team of dedicated health care professionals who know what they are doing. read more

I went to see Dr Mazur after I was injured at work. I had injured both my wrists and my right shoulder. I had 3 surgeries though him over the course of 2 years. Nevermind, that even with an appointment, you will NEVER wait less than 90 minutes to get into see him, in the waiting room. I did it countless times... The wrist surgeries were fair, but took a long time to heal. When i went to have my shoulder surgery, I was told that I likely had a rotator cuff tear and possible bicep tear. I knew the roator cuff was true, but as I repeated told him, that my bicep was horribly painful ALL the time, he kind of just avoided it. Day of surgery, went in, got knocked out and woke up with 3 small incisions around my shoulder. When i asked him about the bicep repair, he said he didn't think he needed to work on it. I have the internal photos of my surgery. There is no proof he even explored that part of my injury, no photo and no pain or bruising in the area he would of had to have looked at to determine such things. So I go home and recover, for a looooooong time, all the while my bicep area still killing me. When I returned to his office a week or so later, to have the stitches removed in those 3 spots, 2 looked fine, and one was clearly infected and had not healed or even started to grow back together, regardless of my careful care of the area and taking antibiotics. His nurse stuck a q-tip type thing about 1.5 inches into the bad wound, which hurt terribly, to clean it out I suppose. I asked if I would need a stitch or two to help close the wound. He said, 'oh-i'll be back in a few minutes" I SWEAR ON MY LIFE, --after he stepped out of the room, I heard him talking to his nurse right outside the door. He said, "I DON'T HAVE TIME TO STITCH THAT UP, JUST CLEAN IT OUT AND BANDAGE IT UP" Are you kidding me!!?? Don't have the time, what-to do what is your JOB and obligation???!!! Did I die? No. Did that wound take weeks and weeks to heal? YES. And I got the joy of a HUGE thick, keltiod scar that stuck out, because he didn't do what was proper and medically necessary!!!! It look like a nipple, on my shoulder. I still have it and it is 8 yrs later. So, if he'll be this lazy and skimp on the details, why should anyone trust him to do what he's supposed to do to you internally, while you're unconcious???!!! All that, and he is difficult to understand and treats you like you have no idea what you are talking about. So --lazy, inconsiderate, difficult to talk to, and you will spend more hours in the waiting room than you do on the operating table-- His approach is to (half@ssed) repair the injury, and has NO CLUE how to talk to patients and listen to their needs and concerns, even when you are writhing in PAIN!!!!! BEWARE of DR MAZURE!!!!! I think its just a business to him. I take my pets to better doctors than HIM!! read more

Really nice MD. I thought we were on the right track with the problem. Turns out it was not my arm / hand at all. The issue was my neck. I needed a different test other than injections in my arm to see "....if the steroid helped even for just a short time..." Realizing this is the main method to test for issues, I gave my answers . However, a nerve conduction test would have provided specific information that the problem was not in my arm whatsoever. Two surgeries later I was at a major teaching clinic in the SF Bay Area where that nerve test was done, as ordered by an arm surgeon. Sadly, I have two large arm scars due to not really fully testing to make a sound diagnosis. read more
