Chiropractic Care

We provide advanced spinal correction utilizing "state of the art" chiropractic techniques. Never in the history of chiropractic have we been able to provide the level of help and expertise that now exists. These newer correction methods are even safer, more comfortable and more effective than ever before. As a Doctor of Chiropractic, Dr. Jon and Dr. Richard  have had many years of training and experience in spinal adjustment.



This is an updated form of a treatment that has been used for thousands of years.  At Callahan Chiropractic, we use electonic meridian therapy using a mensomatic microcurrent therapy unit that uses current to painlessly stimulate acupuncture points and meridians without needles.  According to Dr. Richard Yearee, one of  the first practitioners of acupuncture in the U.S., the mensomatic is as effective and, in some cases, more effective than needles.

Applied Kinesiological Muscle Testing

We are able to evaluate the body using muscle testing.  Used mainly for determining energetical weak points, we may suggest nutritionals, adjustments or other guidance to increase the energy of the points in question.  It is not a form of diagnosis, however, it has proven effective in finding areas that can be improved without the use of drugs or surgery. 

Fitness Training


Our new onsite gym and personal fitness trainers are here to help you with your exercising needs.  We believe that health is multi faceted and we have expanded our services to include direction in exercise including posture exercises. Postural exercises help work on the soft tissues. If your posture is not correct, it can cause problems with subluxation and aches and pains. 

Lifestyle Advice

We often find it helpful to "coach" our patients on certain activities they should avoid or do differently to avoid aggravating their particular health challenge. Our goal is to help every patient achieve a fulfilling and happy lifestyle full of the activities they enjoy most. We recognize that each our patient is a whole person, and help them reach true health and wellness is a collaborative effort between our professionals and our patients.

Nutritional Counseling

We have been using nutritional supplements as part of our practice for decades.  Two of the many nutritional companies we utilize are Standard Process of Palmyra, Wisconsin and Nutri-west of Douglas, Wyoming.  These are both food based nutritionals that are not artificially based and we have found they are much easier to digest and have great assimilation for the majority of our patients.  It should also be noted that we do not utilize supplements that are marketed using multi-level networking or similar means.  At Callahan Chiropractic, our focus is on you and your health, not on signing you up to sell supplements to others.  We provide specific recommendations on nutritional supplements and healthy food choices to enhance our patient´s return to optimal health. Do you know which supplements and vitamins are good for you? We can provide a structured nutritional program based on your individual needs.

We also offer a Purification Program created by Standard Process.  Many of us suffer from an overload of toxins that we acquire from everyday life.  This detailed program is designed to help cleanse these toxins from the body safely and naturally.  Please call us for more information.

Reviews By Our Satisfied Patients

  • "In 2001, I was diagnosed with Meniere's Disease. Doctors wanted to put me on several drugs that were supposed to help ease the condition, but would not get rid of it, only slow it down. I was having some of the worst symptoms that had been described to me, when someone suggested I see Callahan Chiropractic. I decided to give them a shot at helping me. Between adjustments, nutrition, and advice about a healthier lifestyle, the problems that I was having have been virtually eliminated allowing me to go back to a normal life. Not only has Callahan Chiropractic helped me control this condition, but allowed me to feel better and become healthier overall."

  • "I awoke one morning and could barely move. Pain was shooting down my right leg. I have a curvature in my spine, but it had never bothered me like this before. I didn't know what happened, but I knew I had to do something about it. I had never seen a chiropractor before, so my husband called his chiropractor, Dr. Jon Callahan. I had to walk very slowly with a cane. I felt like a little old lady. Dr. Callahan explained that I had a pinched sciatica nerve and gave me my first treatment. I am a waitress and took two weeks off of work. During that time, my treatments and ice were my best friends. Dr. Callahan had helped me so much. My husband and I now get regular chiropractic care. I would recommend Dr. Callahan to anyone with neck or back problems."

  • "I used to suffer from chronic colds and sinus infections. In 1999, my mom suggested that I try chiropractic care to relieve some of my problems. Dr. Callahan suggested nutritional supplements and also gave me a list of foods that I should and should not eat. This really improved my overall health and helped with my sinus infections. I also discovered that I had some back problems, so Dr. Callahan x-rayed my spine and was able to find the source of my back pain. He gave m some adjustments in my neck that helped to alleviate the pain. Dr. Callahan and his staff are very friendly and care about people, making sure that they are healthy and stay healthy. This makes coming to Callahan Chiropractic even more worthwhile. I would recommend Dr. Callahan to anyone with colds or sinus infections."
