What Do Chiropractors Do?
Chiropractors treat patients by adjusting their spines. The spine is made up of small bones called vertebrae. The chiropractor uses their hands to adjust the position of the vertebrae. This helps to relieve pressure on the nerves and muscles up and down the spinal column. Chiropractic care can help to improve joint function, reduce pain, and improve overall health.
Chiropractic care works by correcting misalignments in the spine. When the spine is out of alignment, it can cause interference in the body’s communication system. This can lead to a number of health problems.
When vertebrae are misaligned, it can put pressure on the nerves and muscles. This can lead to pain, discomfort, and other health problems. This is called a subluxation. Chiropractors specialize in finding subluxations and making small gentle adjustments to realign the vertebrae and promote natural healing.
If you are looking for relief from pain or want to improve your overall health, consider chiropractic care.
Chiropractors also offer advice on how to improve your health through diet and exercise. They may also recommend massage or other therapies to help you recover from an injury or maintain good health.

Came in with a lot of pain going thru my right back side from sciatica and george helped me out... made 2 visits and was able to finally have some sleep because as I layed down my nerves are stretched out and had major pain.. im on week 3 I believe with a whole lot better improvement my pain level is a 2 when I came in it was a 9 forsure... still continuing to finish my treatment and after will come once a while to maintain the health of my back and avoid future sciatica nerve episodes
I had a twisted ankle, lower back pain and neck and shoulder pains that extended to my elbow and knuckle. I felt like I was losing my grip. I visited Dr. George Tu’ihalangingie for an adjustment and he treated those symptoms with the best, professional care possible. That relieved all those issues and I highly recommend his services. I typically go for deep tissue Thai massage to treat some of these issues, but the adjustment that I got, was a one stop shop for me. Thank you Dr. Tu’ihalangingie for the job well done. Keep doing great! I am now a regular patron 🙂.
I've been to Malaysia to China to Europe in all around the world and my thing is going to chiropractors and by far by far this one here is the best guaranteed.
I walked into Mana chiropractor after an auto injury from the first day I was able to receive adjustment that brought immediate relief to my neck and relieved my headache. I was referred an attorney. I never had to worry about doctors bills or medical care. Only had a focus on getting better. With Mana Chiropractic and their network I believe I received the best care and understanding. Thank you Mana Chiropractic.
when I first came I was a little hesitant as in sacred. I’ve never been really adjusted before. But Dr Tui made me feel more comfortable and explained everything for me more thoroughly so I can understand everything easier. He made me feel more comfortable and I can’t wait til my next adjustment all the time.. thank you so much Dr Tui!
Great Dr. Really listens to your areas of concerns and gives the best route for everyday living. I went in because I couldn’t stand my shoulder and upper back discomfort anymore.
Been coming here for 3 years maintenance now but it has changed the game for me . He's helped my chronic pain and now im here just for wellness. Im 54 but feel like 33 now since I've been getting care
The Best adjustments of my life time has been through. MAna chiropractic and I might of sounded like rice chrispies but I felt amazing days latter still thank you George. ..
I had a great experience with this chiropractor after my accident. From the first visit, he was very professional, caring, and helpful throughout my treatment. He took the time to listen to my pain and explained everything clearly. The staff was also friendly and made me feel comfortable every time I came in. I noticed improvement with my pain and recovery after my visits. I truly appreciate the care and support I received during a difficult time. Highly recommended for anyone needing treatment after an accident. Five stars!
For the first time in about 5 years, after about 2 months of regular visits. I’m regularly sleeping full nights sleep. I haven’t had any numbness, sciatic or lower back pain consistently for several weeks now. 10/10 recommend. He’s been the most welcoming, friendly, at home feeling chiropractor I’ve ever been to.
Best experience I’ve ever had! I’d never been to a chiropractor before in my life, but Dr George was amazing. Made me feel safe, comfortable from the start, explained everything clearly, and I felt the difference straight away after the session. Highly recommend to anyone thinking about trying it!
Dr Tui is the best chiropractor out there. I was in so much pain after my accident and he fixed my back. He also fixed my swollen ankle and cleared my sinus! I appreciate you Doc!

Dr Tui is a great chiropractor, I highly recommend him to anyone looking for quality care. I’ve started to feel better after only a couple of appointments!
Been a while since I could get a proper adjustment and I finally got to the source of my aching lower back pains. Grateful for the services as well as the hospitality while in office definitely a pleasure visiting Dr Tui
First and foremost, I want to thank Dr. Tui for his long-time, great service. I've been coming to Dr. Tui, my chiropractor, for over a year now, and he has tremendously improved my sciatica and disc damage. There were times I couldn't walk or was in excruciating pain. I strongly recommend him, as he's very knowledgeable and takes good care of his patients. Also, his prices are really good compared to other places I've been to in the past.
Dr. GT is a miracle worker. Immediate relief after first visit. He took his time with explaining everything with me. He is friendly and knowledgeable. I highly recommend him!
This best adjustment I’ve ever had! This guy is professional and really thinks things through before the adjustment. He’s a great communicator and easy to be around. My husband really appreciated that he has an athletic background and can understand needs of contact athletes.<br>We’re so glad we found this place!
I came in with back pains and a lot of skepticism. I didn’t think the adjustments were going to help, but they sure did. The lead chiropractor at Mana was so knowledgeable; I believe his name is George. He shared a couple of exercises that addressed my needs. Good listener. 10/10 I’m bringing my grandma with me next time.<br><br>3/14/2026 Update:<br>I came in from Austin with my back hurting. I had a pinched nerve and Dr. George was able to give me some relief with the Gonstead method of chiropractic. Rating this second visit is 10/10. Still need to bring my grandma next time.
I felt soooo so much better after my adjustments and learned a lot here about what was causing my neck + back discomfort and how to strengthen certain muscles to help prevent the pain from coming back! I feel like I can even breathe better after my adjustment.
Doctor Tui is the best, is helping me with my knee pain, back pain and more, he have a lot patient and explain everything well, also is a great person 👍<br>El mejor Quiropractico q me ha tratado sus precios son muy justos y te da consejos y recomendaciones para mejorar tu salud, es fuerte y con mucha experiencia, definitivamente se los recomiendo 👍💪
Have been seeing Dr Tui for a couple months now and he has helped me so much dealing with a sciatic nerve issue. Really knows his stuff and a true talent and passion for what he does!!
I went in for neck pain and left feeling so much better. The care and attention I received were outstanding. My neck feels more flexible, and the pain has decreased significantly. Highly recommend!
As a full time mechanic , I use the repetitive movements everyday with my hands. George was able to adjust my wrist that was giving me some discomfort. Blue collar guys, or anyone in search of a chiropractor, make the call! Thank you again George!
Dr. Tui was amazing!! He got me in super last minute and was so fast and responsive via phone/text. I had some lower back pain and he was so knowledgeable and helpful not just with helping to align me but also with explaining what he was doing and why. I’m feeling better already.
Awesome visit. Great guy! I work construction and during our safety meeting taking care of our bodies was the topic, Told all my co-workers "if you go see a chiropractor you need to come here". I will be back👍🏼
Husband had and great experience, and we took our pregnant daughter-in-law. She said she was nervous being it her first time and she was 7 months pregnant. She instantly feels much better and all smiles. I will be next🙌
George was the best! I had shoulder and neck pain for years and sciatica. My first couple visits and I already felt a drastic change with my body! He truly knows what he is doing and he explains to you everything you need to know to help better your situation.<br><br>Don't wait till you're old and grey! Get your body right now with MANA CHIROPRACTOR! Yesaaahhh🤙🏽
Had the best experience at Mana Chiropractor. George was professional and made me feel comfortable. Was very knowledgeable and relieved the back pressure asap.<br>He’s found a loyal customer in me, I’ll definitely be using him from now on.
Had a sciatic issue on my right side, Dr. T adjusted me and helped me through some stretches to help with the pain. The best decision I've made was visiting his practice
Dr.Tui is simply amazing. We reached him through a friends recommendation and also by following him on social media. My husband had lower back pain for a long period and also had old knee injuries. Dr. Tui did work magic on him. Since his visit no more complains thank god for that. Pay a visit to Dr. Tui if you want to be better quick. Clinic has a great ambiance and very friendly and accommodating processionals. Very pleased 😁
Dr. Tui is a great chiropractor. Listens to his patients issues, suggests a course of action or treatment. He encourages feedback from patients whether good or bad and readjusts his treatment as needed.
Hurt my back from a work injury and been having lower back problems for years. Wish I would've went to a chiropractor sooner. But I'm glad I found out about Mana Chiropractor. George & his staff were very helpful & friendly. Just had my first session and I can already feel a big difference when I walk, move around, & get up. Happy I found a good chiropractor that cared & walked and talked me through everything as a first timer I was kind of nervous. I was beginning to lose hope but not anymore thanks to Mana Chiropractor. I will definitely be back. Highly recommend!
