I suggest you pay attention to all Dr. Boyd's 1 star reviews. From my experience I'd give zero…read morestars if it was possible. He screwed up my ankle surgery so bad that he said he didn't even feel qualified to try and fix it. So I had to go to a specialist far away from here to have the whole surgery done over again this time with a large second incision with double the metal brackets and screws to fix it properly. Not only did I have to pay for his mistake with the second surgery costs but I also spent the first 3 months after Dr Boyd's surgery in pain with awful abnormal swelling around my ankle and lower leg. Then I lost another 4 months recovering after the second surgery when the specialist fixed Dr Boyd's botched surgery due to having to keep it elevated all that time to heal Properly. Dr Boyd admitted to screwing up the surgery but never once apologized or expressed any concerns about what he'd done. He also was very condescending to me when trying to ask him any questions. He hardly spoke to me during my appointments with him so asking questions was the only way I had to know anything about my ankle, surgeries etc. I so highly recommend that you seek a better Doctor for any surgeries you're considering. No one deserves to go through the pain, lost time and financial impact that I went through because of Dr Boyd. Best of luck to you..

Feeling Great! Dr…read more Boyd did my recent hip replacement, and I couldn't be more grateful. He truly listened, answered all of my questions, and made me feel genuinely cared for every step of the way. The surgery went smoothly, and I felt completely confident in his hands. I am up and about just like new! It's been two months since the surgery. Highly recommend him!

Dr. Peterson is a very nice man. Dealing with his RUDE office manager and another long time…read moreemployee F. is an entirely different ball of wax. I sent letters, called and had no response over a 6+ month period. Finally when I did get a hold of them the employee F. who had initially told me what I was inquiring about lied to me as did the office manager. Calling me a liar and that I should have taken care of this before. Even though I had an attorney who they were in touch with at the time. After being a long time patient and not having a large choice in a small town, I decided to switch to a Dr. In Modesto. I find any person who works for a well establish Dr. should be very careful in how they treat their patients. Like I said it's not the Dr., it is his long time staff who he has no idea what they are doing and how they are treating his patients. I may be the only post here but more than likely it's because in a small town you don't want to be treated like crap and feel like you've done something wrong. When I finally did speak to F. the employee she passed me on to the office manager who screamed at me on the phone and told me it was my fault. My bill was never paid, lie, I should be more responsible, I should have called to see if my bill had been paid, which it was because I called every medical office I'd been to and they had all been paid, I then called my attorney and they also confirmed that they had been paid. So, I get two more letters one 'waiting for my response and the next was a bill just under what they owed me by a few cents!' SCAMMERS!!! Just because of them I would Not recommend that office to anyone ever. If you want an great Dr. With a wonderful staff Dr. A. Nygarrd is the place to go! The 1 star rating is because you have to put something. Staff = 0. Dr. = 2.5
