Patient Testimonials

“I love to hunt and fish, and my knee pain had gotten so bad that I had to stay in the truck while my friends and family were out. My knee was really swollen and everything I did was uncomfortable. Dr. Nonweiler explained my condition to me and told me that I was a good candidate for a partial knee replacement.  I decided to wait to schedule the surgery until the Mako robotic-arm assisted technology arrived at St. Charles, and was the first patient to have this procedure done with it. I have a lot of faith in Dr. Nonweiler, and he made me feel comfortable with the decision and was very easy to communicate with. The quicker recovery time was also appealing to me. It’s very hard for me to express the difference this has made for me. I can do anything now, I can ride a bike, jog, or spend time standing. I used to call it my “bad knee” and now it’s actually my better knee! I have a fishing trip planned in a few months and I’m looking forward to the upcoming hunting season.” – Suzie Twiss  

“I was on my knees gardening and went to get up, when I pushed up with my leg I felt something pop. I felt a lot of pain at the time and it was still hurting a few weeks later so I went to go see Dr. Nonweiler. I had torn my meniscus, and that’s when I found out I had osteoarthritis in my knee. He fixed that, but my knee never did completely stop hurting. I waited about a year and a half before coming back in and tried a cortisone shot, and that didn’t relieve the pain. I am an artist and I need to be able to get around so I can continue to work. I couldn’t even go shopping, or even walk, without really pacing myself. I was very pleased that I was able to get a partial knee replacement. I figured it would heal faster and once the swelling went down, I didn’t feel any pain. I’m ecstatic about it really. I can’t tell he did anything other than the fact that I have no pain.” – Karen Snider

“I had arthritis in both knees, I love to walk and I have young grandkids that I couldn’t play with because my knees were so bad. I had my first knee replaced in January by Dr. Nonweiler at St. Charles. They took good care of me, but I had to stay in the recovery room for six hours because they couldn’t find a room for me. I got really sick from the pills in recovery, I couldn’t eat, and by the time they found a room for me I was too sick to start therapy. I decided to do the second knee replacement surgery in October at Cascade Surgicenter. My nurse Rene made the whole experience so easy. I had the surgery at 7:30 a.m., and she had me fully dressed and walking by 11:00 a.m. I ate lunch, took a nap, and I left at 3:30 p.m. I live in Prineville, so I stayed at a hotel close by in case I needed to contact Dr. Nonweiler or the nurses. The hotel was great, they had ice ready in my room and I was able to rest so much better than at the hospital. They even brought the continental breakfast to my room! The next day, I went back to Cascade Surgicenter and my nurse Rene was there for the follow-up appointment. The one-on-one care at The Center was unbelievable, I wish I could have done both knees there. My life is so much better now that I have had both of my knees replaced, I’m very happy with both of them.” – Rosalee Case

“I have been extremely pleased with the implants. The breakthrough for me came in the summer of 2012, as I was wiring a travel trailer, and realized that I was kneeling on a concrete driveway in shorts and not even realizing it. This would have been unheard of prior to the procedure. I continue to enjoy a robust outdoor Central Oregon lifestyle that includes hiking, cycling, hunting, snowshoeing, cross country skiing, and other activities. Given my experience and the ongoing advances in technology, I would not hesitate to recommend partial knee resurfacing to a patient whose history and symptoms warrant consideration of such a procedure.” Continue reading… – Ray Spreier 

“This surgery was the best decision I have made, medically. I no longer have pain, my range of motion is so much better before, I can sleep all night without pain, and my strength is greatly improved. Great team support. I had practically no pain since the day of surgery.” – Kathleen Zwonitzer

“Thank you for investing your years of education to give me the best possible outcome on my ankle surgery. I really appreciate your bedside manner, as your communication with me has been awesome. I would HIGHLY recommend you as I feel I got the best! Wishing you the best in 2016, as I will soon be running or skating again this year!”– Eileen Plunkett 

“Just a quick note to let you know how well I’m doing after my knee surgery. We’re in Arizona now and my Canadian friend has had me out walking, golfing and dancing. I would do that even if she wasn’t insisting that I walk. I ride my three-wheeler bike every day around the resort. I have a small amount of pain from time to time in bed, but that’s all.  You have given me my life back.” – Linda Engebretsen

After severing his quadricep, Bill Tye came to Dr. Blake Nonweiler to surgically repair it. After letting it heal and doing therapy for three months, he is “back in the saddle”, as seen here rounding up cows on his bike. He said, “Dr. Nonweiler did a super job and was very personable. I was a basket case after my injury and he made me feel calm and confident I would be able to recover. He was right, I am doing great!”

“Doc Blake, this is Ron B. and you repaired my right arm 9 months ago tomorrow, the 23rd. You said you could rid me of the pain I had for many years, and boy did you ever. I sleep all night now and if I move my arm the wrong way, it is pain free. You are the man with “magical fingers.” I know that you have heard this many times before, and you are going to hear it again. THANK YOU and give the crew that helped you on that day a hug for me. I really hope that you and your family, the great crew of people that you work with, have a great Holiday Season.” – Ron. B

“After a freak accident with my horse that dislocated my shoulder both forward and backwards and left me with numbness in my hand and pretty severe pain upon any motion, Dr. Nonweiler repaired me with minimal pain and interruption in my life. I not only drove myself to physical therapy four days post-surgery, but I was driving a tractor hauling tandem scrapers just ten days after my surgery! The physical therapist’s (2) that I saw following surgery were both so impressed with my recovery, both stated that I was at least 3-4 weeks ahead of anyone else with the same surgery they had ever treated. I was so thrilled with my results that my mom had TOTAL SHOULDER REPLACEMENT by Dr. Nonweiler just one month ago, and the physical therapist she saw told her he had never seen anyone recover so quickly, let alone an 80 YEAR old! I can only say he has a technique, a professionalism, and a personality that is exceptional. You won’t find a better surgeon or nicer person anywhere, and I worked in the medical profession for nearly 30 years and the operating room at least 2 days a week for 20 years before I decided land leveling was a lot more FUN!” – Cindi R.

“Dr. Nonweiler, It’s been close to 8 months since my total shoulder. I wanted to let you know that I am extremely happy about this entire process. I didn’t imagine it would go this well. Thanks Again.” – Dwight

“Thank you so much for speaking at our meeting at Skamania. Your evaluations are amazing, among the best of the conference! We would love to have you back.” “The cadaver knee was fantastic-thank you.”“Dr. Nonweiler was the very best speaker of this meeting-very clear, great handouts, and even a cadaver knee which helped to visualize the problems which were discussed.” – Kerry, Oregon Association of Family Practice Physicians

“Karin and I had a very good time at the course and we learned a lot. Seeing the reverse total shoulder arthroplasty in the lab was a great experience and helps tie everything together. It was good to get a refresher on surgical treatment of the overhead athlete as well. Thanks for the informative course. We look forward to the Spring courses each year since it is close and put together so well.” – Brock M., Physical Therapist

“Dr. Nonweiler is incredible; when I was 70 years old I was dead set against having my knee replaced, Doc. Nonweiler knew this and worked with me for years to keep the pain down and did not push me into surgery. Doc Nonweiler just grinned and said that I would know when I was ready. Well it has been a year now since my knee replacement and what a relief. At 74 years now and 20 lbs lighter, how I love to park as far away from the stores a necessary. A BIG HUG from my wife and I to Dr. Nonweiler and his wonderful staff.” – Doug Gadd

“I had a knee replacement performed a year ago by Dr. Nonweiler and everything is great. The pain is gone and I have full use of the knee. I am very happy with Dr. Nonweiler’s willingness to answer questions and take the time to explain details in a manner that is understandable to the patient. He is a very friendly and skilled professional.” – Jack K. “Am happy to report one year following a total knee, I have been able to hike, bike, snowshoe and cross-country ski. No pain. Thank you, thank you, it’s wonderful to be able to be outdoors again.” – Carol S.

“I’m an epileptic and had a few grand mall seizures that broke the humerus (the bone in your upper arm). Then I had another seizure about a month later that broke the ball off the head of the humerus. It broke above the other breaks, so I had to wait for them to heal before I could have surgery. I was in a brace for six months total before surgery which made the muscle break down severely. I finally got the surgery three months ago and am still in physical therapy. I have surpassed all Dr. Nonweiler’s expectations of range of motion. The most important things are I am functional again and completely pain free. I received a half a shoulder replacement because the socket is still in good shape. A huge thank you to you Dr. Nonweiler and all the staff that helped out that day of the surgery. you have truly given me my life back. You are a fantastic surgeon.” – Kevin Smith

“Dr Nonweiler, thank you for repairing my left knee, you said i would be in good shape in 10 days post op. you were right! today is day 10 and i have been walking limp free and starting to ride my bike for a couple of days now. cant wait to start running again soon. Thanks again!” – Arnie T.

“I am 74 years old. In October, 2012 while descending from Middle Sister, I slipped, and severed the Quad Tendon. I wanted a excellent sports physician, and selected Dr. Blake Nonweiler. He performed the surgery, doing an exceptional job, and now a little over three months later I am walking over two miles a day, almost a full work-out at the gym, and pain free. Thanks Dr. Blake.” – Gary Metternich

“My meniscus surgery with Dr. Nonweiler went better than I could have hoped for. Everyone involved was professional and friendly. The actual surgery and recovery was quick and easy. I did not need crutches or even a cane. Pain was minimal and I was hiking again in a few weeks. It has now been 6 weeks and I am pain-free.” – Mike

“My knee was to the point that I could not do very much out of doors without problems. I had Dr. Nonweiler do a knee replacement surgery for me in Dec. of 2012 and since have not looked back. It is something that I should have done long before I did. It has been virtually pain free and my knee and leg are as strong as my other leg. I can’t say enough good about the surgery and the care I got.” – Carol Stout

“When my shoulder started giving me more pain than I could withstand, I sought out to find an orthopedic doctor. After asking everyone I knew who would you see for shoulder problems, Dr. Blake Nonweiler’s name repeatedly entered the conversation. So with this information I made an appointment, this was approximately two years ago. After x-rays and a physical examination it was determined that arthritis was the root of my shoulder problems.  In December of 2013, I had total left shoulder replacement surgery. At no time during the whole process was I not informed completely of what to expect, and was totally surprised at how fast this process progressed. I really appreciated the professional, common sense approach that I received from Dr. Nonweiler and his staff.Now let me fast forward to March of 2014. I have completed physical therapy. The pain I once had in the left shoulder is gone, and I am only three months out of surgery. The physical therapist was amazed at my speedy recovery. With great appreciation, respect and gratitude I would like to thank Dr. Blake Nonweiler for giving me back my mobility and being pain free. It is with great pleasure that I would recommend Dr. Blake Nonweiler for any orthopedic surgery you may need in the future.” – Shirley L.

“I tore my MM and ACL wakeboarding July 2013 and had surgery 08/21/13. My knee is doing fantastic, the scars are barely visible and my hamstring is healing just like it should. I am getting stronger every day. I can not wait to get back on my wakeboard this summer! Thanks Doc to you and your staff. You did a superb job! So did the folks at Therapeutic Associates!” – Edie
