Reviews By Our Satisfied Patients

  • "I have been seeing Dr. Harper for 2 months. The drastic change from my initial x-ray to one month later is a miracle. The sciatica I had been bothered with has now subsided. Constipation has ended as well as my headaches. Overall, I feel better and feel blessed that Dr. Harper was led to our area.
    His one desire is to help his patients! He has become my friend."
    Mary W.
  • "I've been using chiropractic treatment for years and I love Dr. Harper's techniques. I'm almost through my initial treatment plan to correct my neck curve, lower back, and hip pain. I feel amazing! I'm getting my life back on track, not having to deal with the pain that kept me from many of the activities that I love. Besides having less pain, I have my sense of smell back that I didn't even know I was missing."
    Cathy F.
  • "Dr. Zack is awesome.....I love the precision and gentleness of the technique and the care and accuracy that Dr. Zack delivers....he has kept me on top of my game!!"
    Yvonne T.
  • "The best!!! I’ve visited him many many times! Gentle, easy technique! He does not give up on getting your problem areas fixed! You cannot go wrong with Dr. Zack! I’m living proof as a nurse I couldn’t walk without chiropractic care!"
    Tracy W.
  • "Visits to Physical Therapy and massages provided temporary relief for periodic shoulder muscle pain. I knew if the root cause could be determined, the issue could be fixed. Dr. Harper found the cause to be the misalignment of my Atlas and scoliosis. The Atlas was immediately corrected and after only 4 weeks, the x-rays showed nice improvement in straightening the spine and correcting the scoliosis.
    Corrections to the body take time. Just as braces don't straighten teeth in a few weeks, true chiropractic care with the goal of healing the body requires adjustments over time.
    I'm blessed that the ONLY Atlas Orthogonal Chiropractic practice in East Tennessee is only 30 mins from my home."
    Carla M.
  • "After suffering for years with osteoarthritis, I was able to finally find relief with the AO and Activator adjustments that Dr. Harper uses. I was even able to stop taking my Celebrex that I had been dependent on for years! I have been to other chiropractors before, but never really cared for having my neck cracked. The care at Southeast Precision Clinic is top notch. I highly recommend this place!"
    Randall H.
  • "From my first visit to present, I have felt better since becoming a patient of Dr. Harper. I no longer have the pain that I once did. Blood pressure has lowered and I feel better overall.
    He is a God send!"
    Ralph W.
  • "I heard about Dr. Harper from a friend. With the different issues I had been having, I needed to find a new chiropractor to see if these could be resolved. From the 2nd visit, my health issues with the knee, hip, low back, & headaches have greatly improved. I noticed about 10 mins. after I left my 1st adjustment, my sinuses opened up. Also, my lower back was not hurting, and my hip was not stiff anymore.
    I am so thankful for what Dr. Harper has done for me!"
    Sandra M.
  • "Dr. Harper has helped me with my hip pain tremendously. I could stand to have pressure against my lower back or hip areas, but after these gentle adjustments, I am amazed at how the soreness in my hips has greatly decreased. I hardly felt the adjustments, yet the results have been nothing short of impressive!"
    Glenda H.
  • "I was suffering from headaches and neck pain. I had been experiencing soreness and stiffness, as well as muscle spasms. After several visits to Dr. Harper I have seen success."
    Robert W.
  • "I suffered from chronic migraines. I had been in a bad accident 15 years ago. Dr. Zack showed me on my x-ray that my neck had lost its natural curve. after two months, my neck has curve back to it and my migraines have improved drastically."
    Sarah E.
  • "I injured my back in early August and could not move due to extreme pain. After three weeks of treatment from another local chiropractor, there was little change. I heard of Dr. Harper who offers Atlas Orthogonal procedures, had just opened his practice in Knoxville. I knew I had an issue with my Atlas alignment as well as a lower back injury. Dr. Harper began three treatments a week and I immediately felt relief. After four weeks of treatments to the neck and lower back, I am pain free and the adjustments are holding. I will be able to take a major trip out of the country, which four weeks ago was going to be impossible!"
    John J.
  • "I came to see Dr. Harper for hip and back pain. I was having difficulty sitting at my desk all day and trouble sleeping because of the pain in my hips and lower back. After the first couple of visits, the pain has subsided. After 30 days, I am moving and sleeping much better."
    Amanda D.
  • "I separated my scapula at the fair and have always had bad migraine headaches. Dr. Zack was able to put my scapula back in place with very little discomfort. After that, I continued to see him for my chronic migraines. I was able to avoid surgery to fix my shoulder because of Dr. Zack's abilities. I have much less frequent headaches now and have had no more problems with my shoulder/scapula since starting care."
    Amber W.
  • "I have suffered from years of pain in my neck, back, shoulders, and knees. I had to give up bowling and dancing due to the pain. I also had trouble sleeping because of the pain. This pain had worsened over the years and I had seen many doctors. I had 2 surgeries on my lower back along with many cortisone injections. I had a lot of trouble getting out of a chair and standing. I also couldn't walk very far without limping. After seeing Dr. Harper for 30 days, I am able to get out of a chair easier and waking easier. I can now walk short distances without much discomfort. Going to the grocery store is not as difficult anymore. I feel that I am sleeping better now than I was before coming to see Dr. Harper."
