When my longtime chiropractor passed away, I wasn't sure I would find someone I trusted as much. Thankfully, he stepped in and has been outstanding. Dr Theriault is incredibly thorough, knowledgeable, and genuinely takes the time to assess and diagnose the root of the problem instead of simply treating the symptoms. I never feel rushed during my appointments, and he always makes sure I understand what is going on with my body. Every visit brings noticeable, often immediate, relief. His expertise, compassion, and personalized approach have made the transition much easier, and I feel fortunate to have found such an exceptional chiropractor. I highly recommend him to anyone looking for quality chiropractic care.

Dr. Mark has been nothing but amazing when it comes to helping me manage the demands of collegiate athletics. As a 19-year-old field hockey player, staying healthy and pain-free is essential, and he always makes sure I'm in the best shape possible to compete.I have dealt with numerous back issues, and many people were unable to help, but Dr. Mark took me in right away and worked with me to get back on track. Thanks to his care and expertise, I can continue playing the sport I love without constant pain.As a young adult, I would highly recommend seeing Dr. Mark. He genuinely cares about his patients, takes the time to address their needs, and helps them leave feeling their very best. I'm incredibly grateful for all of his support and would recommend him to anyone looking for exceptional care.

I started seeing Dr Theriault when he took over the practice. Glad I stayed as he has been great in taking care of preexisting issues I had as well as helping me with the abuse I put my body through

My husband and I appreciate Dr. T's range of chiropractic applications, affordability, gentle nature, friendly personality, and so much more! We always depart being more educated about something that will improve our mobility and relaxation techniques. As well, we have a smile on our face and a heart full of gratefulness for his effective, professional treatment, and his sense of humor. He is a very intelligent and considerate practitioner. We have been receiving chiropractic care for over 20 years, and he ranks very high on the standard of excellence scale.

Great Doctor, Dr. Theriault has helped me with my chronic back and neck pain and now I can sleep better at night. I would highly recommend him. Do not hesitate to make an online appointment with him.

Dr Mark is very knowledgeable and patient. I will absolutely be coming back as often as I can. He uses different techniques do accomplish what my mind & body needed. Insurance isn't a hurdle and his pricing is good. Thank you Dr Mark

I recommend Dr. Mark and his practice due to the high level care that he has used to take care of me. From lower back pain to upper shoulder and neck stiffness, he has provided top of the line adjustments that help me feel much better every time I leave his office. His level of expertise seems second to none. He has a great way of explaining/ educating you on what your body is going through as he adjusts you. I truly believe in the body having the power to heal itself with proper routine maintenance and Dr. Mark’s high level of experience definitely aids in recovery. I can also credit Dr. Mark with being able to help me clear a brutal sinus infection. I suffered for weeks and the day after his adjustment, I began to drain and was 100% on day two. The man knows the body and how it functions and I’m happy to be a client in great care.

Mark was amazing! Very patient and understanding while dealing with someone that suffers severe anxiety. Explained what he would be doing and set the patient at ease!

2025-12-03T22:59:55.089Z

Dr. Mark is beyond outstanding. He makes adjustments in areas I didn't even know needed adjusting. Always leave feeling 100%!

Dr. Mark Theriault is one of the best chiropractors around. He’s patient, thorough, and really knows his stuff. Unlike a lot of places that rush you in and out, he takes his time to make sure you’re actually getting the care you need.What I really appreciate is that he keeps his prices affordable and works on a fee-for-service basis — no big contracts or pressure. As a blue-collar guy who works hard for a living, it means a lot to have someone who makes quality care accessible and actually listens.If you want a chiropractor who treats you with respect, takes his time, and truly cares about helping people feel better, I highly recommend Dr. Mark Theriault.

Forget pain meds. Forget urgent care. Forget your doubts about chiropractic care.If you’re in serious pain and don’t know what to do — go see Dr. Mark. He will fix your back. Full stop.After months of worsening back pain during and after pregnancy, I woke up barely able to move. I couldn’t walk, bend, or lift my baby. Painkillers did nothing. Desperate, I took a chance on Dr. Mark — and I’m so glad I did.After the first visit, I could move again. After the second, my pain was almost completely gone. By the third, my back felt better than it had in years.Dr. Mark is incredibly skilled, kind, and intuitive — he reads your body and knows exactly what it needs. Affordable, effective, and life-changing. I’ll be going monthly from here on out. I’ve never spent a better 50$ in my life.Even my mom, a lifelong skeptic, is now a believer.Don’t wait. Don’t suffer. GO — Dr. Mark will fix your back!

I pulled my lower back out 5 days before my sisters wedding! I went there 2 times before the wedding and by the wedding day I was back to new. Thank you so much!!!

2025-10-06T18:47:38.678Z

My first time seeing a chiropractor. Dr. Mark Theriault was great to work with. He gave me an evaluation and explained what was going on with my body. Explained what he was going to do and why. I left confident I am getting great care.

Thanks to Dr Clark I was able to walk into his office in so much pain and walk out with that pain released. I was not able to lay down as my SI joints were out of place causing a lot of pain. It’s amazing what a chiropractor can do with putting your bones back i to proper positioning. Thanks so much

2025-03-23T13:43:07.944Z

I was hurting and sore when I went in in my knee, hip, and neck. Felt great and relaxed and no pain when I left! I'm conibg back!

2025-02-06T02:13:03.891Z

Always a wonderful experience.

2025-01-23T12:39:32.239Z

Very easy. Very convenient. Do recommend

2025-01-22T15:29:46.376Z

We started going to Dr. Jeff for overall family wellness, but after two close pregnancies and breastfeeding two small kiddos, I am undeniably in a bit of pain. After my very first adjustment, my sacroiliac pain that I had during both pregnancies and that was hanging on even after my second was born was completely taken care of! I didn’t explicitly tell Dr. Jeff that I had this pain as it was something I almost subconsciously lived with, but I’m so glad it’s gone!

2025-01-12T23:45:11.406Z

I used to get adjustments, but would still have pain. After seeing Dr. Clark the first time, and each time since, there is no pain afterwards. It’s been an amazing experience, and I’m so fortunate I had someone that recommended him to me.
