After many doctors and treatments over the years, I am 74, my daughter found him for her son.
I have suffered many concussions over my life, after neck surgery, and in the end they wanted me on strong med's for the rest of my life -- there was nothing the medical profession could do.
Have been working with Dr. Siegfried for a while now and can start to see a small light at the end of a long tunnel. I am off, or way down in dosage, most med's now and look forward to the day of a clear and bright brain.
I am forever grateful for the Doctor and his staff. They have taken such good care of me and never have given up on me.

The most recent one started in 2011 and continued off until about a month and a half ago. The nose was really completely plugged off and I heard about Dr. Siegfried on the radio. I knew him from past things he had done for me and always helped me so I called up and came in. He started the treatments on me and I have had 8 now. I started noticing improvements after about the third one. I have been completely clear for about the last month and a half and the results of it are according to my wife, I no longer snore. I don’t have sleep apnea anymore. I am sleeping through the night and I am breathing really well with no blockage in my nose, it’s amazing.

Dr. Siegfried has been a “life saver.” Dr. Siegfried performed the nasal specific adjustment which provided immediate relief for my severe headaches. Dr. Siegfried also provided treatment to my neck, shoulder, back, and hip. I have had experience with many other chiropractors and other health care providers for treatment of injuries to my neck, back, and shoulders. Dr. Siegfried is an outstanding clinician and has provided great relief of my symptoms. He has provided great assistance in my recovery. I will be forever indebted to him and I am so grateful for all he has done. read less

I was referred by a friend who came to Dr. Siegfried.... read more(5.0 star rating) My name is Jonathan Van Norman. I was referred by a friend who came to Dr. Siegfried. I was having extreme problems breathing for several years, I'm guessing, conservatively seven years. Towards the last several months it was torture trying to get to sleep and stay asleep. And my days I would wake up miserable cause I, I have just endless two or three hours here, asleep, three or four hours there asleep. I went to doc, I went to doctors, several of them they would prescribe me nasal sprays. It didn't work. I was in and out of their offices with very little help or I guess the word would be concern. So frustration finally was at its height and I was referred by a friend who has seen Dr.Siegfried. And after the first time getting my nasal adjusted, I slept solidly 10 hours.
But each time that I've done it, I feel like I have taken some of my…. most of my life back because I can get to bed. It's easy for me to sleep. I can stay asleep. My wife isn't complaining and going to the couch because I snore. The key thing is, is I feel like I have a quality of life back that I haven't had back since at least 2012. And I was miserable for all those years until now. This is my sixth or seventh time coming. I don't remember, but I can breathe out on my nostrils. I can go to bed at night and I wake up with energy and without that, if I ever had to go on four or five more years like this, I don't think my sanity would have been able to let me keep living anymore.
I mean, it's just when you can't go to sleep and you can't get good rest, it's just when they say that you don't, if you, if you don't have your health, you don't have anything. That is really true. And I feel like I'm getting that back. I just got another adjustment on nasal passages and I felt like a million bucks right now. I can breathe out of both nostrils freely and it feels great and I am not going to stop until I can continue to breathe normally, like I used to be able to, which I feel like I'm going to be able to achieve that. read less

The adjustments are thorough and professional and effectively relieve pain, while the specialized nasal canal therapy has completely ended my migraines.Also, Dr. Siegfried gave me a special pillow for my neck that really helps to keep things aligned between visits. I highly recommend Dr. Siegfried and his excellent staff. read less

My husband drove me 4 and a half hours the first time to see Dr. Siegfried in the hopes he could help the spinning stop from my Meniere's diagnosis when nothing else seemed to be working. I was at the end of my rope and Dr. Siegfried after just one bilateral nasal specific treatment gave me relief that made me feel as though healing was definitely an option again. My spinning (vertigo) episodes had been coming daily together with hours of vomiting and absolutely no quality of life. After that first evening treatment on an hour long drive back to our friends house in Corvallis, I, for the first time since I could remember, felt a feeling of happiness and relaxation that I forgot could exist inside my body. I think I talked nonstop to my husband, who commented that I hadn't really been talking any more and it was nice to see. My body had been in the constant 'fight or flight' mode and I was now able to relax. Dr. Siegfried warned that my body was going to need to shut down and rest, almost like a computer that needs to be rebooted. Boy did I! I slept for 15 hours straight with no bouts of spinning. The most amazing thing about Dr. Siegfried is how much he really cares about his patients. He called me the next morning it check and see how I was doing, even though I would be seeing him again later that same day. I was working with every doctor you could imagine at that point but no one else ever showed me that level of compassion. His nutritional knowledge is far superior to the other nutritionist and health coaches had been giving me. He got me on an amazing protocol which he himself does and spent so much of his time working with me on nutrition along with the BNS treatments. Since I live so far away I did attempt to find local practitioners who also offered BNS treatments so I wouldn't have to drive so far. I tried three different practitioners and never found the same relief I get from Dr. Siegfried. He even went so far to speak with a practitioner here to coach them on how to do it correctly, but it just wasn't the same. Dr. Siegfried is the master. It is coming up on two years now since I met Dr. S and if there was only one doctor and treatment I could keep to help me with my Meniere's Disease it would be Dr. Siegfried. I have worked out a schedule and know when it's time to see him again when my body starts feeling uneasy. My husband and I happily make the 4 1/2 hour trip one way every two months or so because there is no substitution for the best. His front desk employees have also always showed us kindness and compassion. My husband and I consider Dr. S like family and are so grateful to have met and know him. You would be among the lucky ones if you choose to work with Dr. Siegfried. read less

His medical knowledge and dedication towards his patients is truly a blessing . Over the years he has helped me maintain good health thru his treatments and knowledge of what whole food vitamins to take which he has available, which is a tremendous help with the heavily processed foods we consume today. His genuine concern for his patients is truly remarkable like the doctors of yesterday who have been heavily influenced by big pharma companies.

NO MORE ALLERGIES! Always professional and super knowledgeable! For more then six years I suffered of Allergies I would have to follow up with ineffective treatments (Nasal Sprays, Pills) from Medical doctors.... Later on I found Dr. Siegfried who was a huge help. WithThe Nasal Specifics I was able to breath right alway, the stuffy nose was gone. Today I don't have to take any medication for my Allergies. Another great thing he did and that I’ll be thankful my whole life is helping me out with my 3 month old Albert, his first month of life my little one was on the line of getting Jondis so I had to introduce him to formula for his tummy to get rid of those bad cells. Right alway he started to get really constapated. I tried numerous of formulas you name it (Similac, Similac Sensative, Rice Formula, Gerber Sensative, and last Soy) he started to have Diareah and didn’t stop after two weeks, I was desprite and willing to try anything. Dr. Siegfried suggested for me to give him Organic goats milk. Right alway I saw a change in his stool. It took him like a day to recover from his diareah. Now he sleeps better. Thank you Dr.Siegfried for always being so caring and going out of your way to help anyone. read less

I have a list of professionals and specialists to whom I refer cases that are outside my area of expertise. For patients with chronic sinusitis, earaches, vertigo, auditory or ocular problems, history of head injury, facial or upper airway problems, and the patient is not responding to spinal care, I consider the possibility of cranial motion or alignment abnormalities. This is when I consider possible Bilateral Nasal Specific technique.For this approach, I refer to one and only one practitioner, Dr Siegfried, who I consider to be the most experienced, capable individual to administer this remarkable procedure. For the last two decades I have referred all patients needing a Nasal Specific to Dr Siegfried, and the response they give is typically one of astonishment, in both the procedure itself, and in the results. Thanks, Dr S, for being a valuable resource! read less

Having practiced since the early 1980's I have had the privilege of seeing many patients with a broad spectrum of problems and complaints. I have also had the privilege of meeting and working with clinicians who have developed and mastered skill sets that complement the techniques that I have learned. There is a great advantage to referring a patient for specialty treatment. It typically improves their recovery time, and it also tells the patient you truly care about their well-being. One of the most profound and advanced manual medicine procedures is the BNS, Bilateral Nasal Specific. For a patient suffering from an assortment of problems ranging from TMJ, migraines, tension headaches, sinus problems and even ear disorders, BNS can be incredibly effective. One of the pioneers of this technique was Dr. Stober, who was an old timer when I was at W.S.C.C. He demonstrated and taught BNS. Regrettably Dr. Stober passed away several years ago. Fortunately for us, one of his students has continued on the tradition and legacy of Dr. Stober’s work. Dr. George Siegfried is a master of BNS. His successful treatment of difficult head pain cases greatly compliments all aspects of chiropractic and other forms of body work. If you have a whiplash or concussion case that you feel may benefit from additional clinical expertise, or a patient with head pain that is not responding as you would like; I strongly believe your patient will come back and thank you for it.Dorian Quinn PScD, LAC Clinic Director Simple Wellness Clinic,Portland Oregon 2018 read less

I had high hopes for what kinds of results I would get from doing it, and have noticed positive changes in everything from posture, mood, concentration, eyesight, to speaking and singing.

I am so grateful to have found out about nasal specific and feel very lucky to have such a wonderful doctor as Dr. Siegfried. You can tell at once that he is just a really good human being. The thought of nasal specific had me nervous at first, but Dr. Siegfried makes the whole process easy as pie. He is very understanding and will go at whatever pace is comfortable for you.
