About Our Services

If you are looking for a safe, non-invasive treatment option that avoids surgery and medication, then chiropractic care is the way to go. Our chiropractic team is capable of resolving a wide variety of conditions. Our most effective services include:

  • Joint manipulation - Our chiropractor is capable of performing skilled joint manipulation techniques, including traditional manual chiropractic adjustment, the activator technique for joint misalignment, and flexion distraction to create pain relief for the spinal column and its discs.
  • Corrective exercise - We prescribe individualized exercise plans that focus on rehabilitation and strengthening of the body.
  • Electrical therapy - Electrical muscle stimulation is a technique known to ease muscle tension, pain, and spasms.
  • Diagnostic technologies - We use computerized images, digital X-rays, and other diagnostic tools to accurately assess a patient's condition. 
  • Massage therapy - This ancient technique creates relaxation for the patient, which in turn promotes better blood circulation for the body's muscle fibers and soft tissues.

Reviews By Our Satisfied Patients

  • "I can’t even explain or begin to say enough nice things about this place. The staff is very professional, kind, and warm welcoming. Dr. Tinker is definitely one of a kind. Not only does he listen to your problems, he goes above and beyond with detailed reasons and solutions. If you are in need of a chiropractor then look no further. Would definitely recommend and will thoroughly enjoy the rest of my visits."
    Brian W.
  • "If you are looking for a second opinion or just a new chiropractor...no more searching!!!
    Dr. Tinker will explain you with details what exactly you need and then he will provide the best adjustments you will ever experience. I’ve been through many Chiropractors and I can assure you will not need to look further after you first visit. The staff is incredible! Very professional and you will be treated as a new part of the family. I love this place! Thank you Sambursky team for a great service!"
    Ricky R.
  • "I've been seeing Chiropractors since I was about 7 years old so I consider myself a bit of an expert. I've been to rough guys who made you wonder if they were doing more bad than good. I've been to ones who focused on selling you supplements instead of making you feel better. And I've been to those that just seemed to be intetested in how much they could get out of my insurance company for physical therapy. At Sambursky Chiropractic, Dr. Tinker focuses on making you feel better! It's that plain and simple. It's about your health and comfort. And everyone on staff makes you feel good that you came in."
    Cindy B.
  • "I highly recommend Sambursky Chiropractic! I had been dealing with some shoulder, neck and lower back pain for about 2 years and I had finally had it. I went to physical therapy first and did not receive any relief. On a whim I tried a chiropractor. I’ll admit I was a little apprehensive at first. However, after meeting the team at Sambursky, that feeling went away. They were so kind and caring. Dr. Tinker took his time to explain the pain I was experiencing and started me on a regimen that brought me relief. I was impressed! I still am! It’s also extremely affordable. It’s a win win situation. If you’ve been dealing with acute or chronic pain and thinking there’s no way out, I’m here as a believer to tell you that Sambursky Chiropractic can help you!"

  • "Dr. Tinker is the best chiropractor I’ve ever been too! He takes his time to explain what you’re experiencing and makes you feel comfortable and cared for. The staff is very kind and they are always ready to answer any questions and accommodate their patients. I love this place !"
    Francis F.
  • "Dr. Tinker and his staff are amazing! Incredibly friend with above and beyond service. Dr. Tinker fixed my neck pain with just one adjustment. They have top of the line equipment and knowledge. There's nowhere else I would go for chiropractic care."
    Cat A.
  • "Dr. Tinker has been amazing. He has been exceedingly patient in explaining my condition and he listens to what's going on. His office is relaxed and has never over-scheduled. I always feel better after I go. Best of all, he doesn't mind if you ask questions during the treatment. Previously, I had only been to a chiropractor once before, and that guy seemed to be the used car salesman of the medical world, so I was a bit of a skeptic. Dr. Tinker is that guy's polar opposite - he is honest, forthright, and gives his profession a good name. I highly recommend him!"
    Lizzy B.
  • "I haven't felt this good in a long time. My feet no longer hurt at the end of the day and I can walk pain free.
    The office staff is friendly and amazing! I love this office."
    Kristin G.
  • "I love the service I receive at Core Chiropractic, The staff are very nice and welcoming to all patients. Justin is amazing and will take the time to explain treatments. I went to Justin for neck and back pains and to improve my posture. If you are looking for a chiropractor to treat you like a member of the family then go to Core Chiropractic."
