Dr. Shannon Greenlaw

Dr. Shannon Greenlaw


Dr. Shannon Greenlaw first received his Bachelor of Science Degree in Biology at Dalhousie University, and then went on to earn his Doctor of Chiropractic degree from Palmer College of Chiropractic in Davenport, Iowa in 1997.

After working for a number of years in several locations in Nova Scotia, he finally settled in at Sackville Chiropractic Clinic. Dr. Greenlaw is an avid golfer and guitar player. He also enjoys staying fit with soccer and ice hockey.

Dr. Greenlaw utilizes several techniques in his patient management, including:

Activator Methods is based on the postulate that understanding body mechanics and force is the key to understanding how to move bones. A leg test is utilized to tell the doctor if the subluxation exists, chiefly in the lumbo-sacral area or cervical region of the spine. With further research into body mechanics, W.C. Lee D.C. and A.W. Fuhr D.C. were able to analyze the body and produce from the analysis consistent changes using a light non-force specific chiropractic adjustment. Lee and Fuhr understood that force was not necessary to correct subluxations in the body. Two components are necessary for fast, effective reduction of nerve pressure caused by subluxations. They are speed and line of drive. Speed and line of drive are what make chiropractic the distinct and dynamic art and science that it is. The activator instrument was designed to deliver this specific dynamic thrust. It is a small hand-held gun-type mechanism that delivers a sharp percussive thrust upon triggering. The activator instrument controls the force and speed of the adjustment exceptionally well and with the activator, the line of drive can be more specific.

ART is a patented, state of the art soft tissue system/movement based massage technique that treats problems with muscles, tendons, ligaments, fascia and nerves. Headaches, back pain, carpal tunnel syndrome, shin splints, shoulder pain, sciatica, plantar fasciitis, knee problems, and tennis elbow are just a few of the many conditions that can be resolved quickly and permanently with ART. These conditions all have one important thing in common: they are often a result of overused muscles. ART is non-invasive, very safe, has virtually no side effects, and has a record of producing very good results. When a soft tissue problem has resolved the symptoms will not return unless the injury happens again.

Cox Technique founder, Dr. Cox explains Cox Technique / Flexion-Distraction as a marriage of chiropractic principles with osteopathic principles. These principles were set forth by Alan Stoddard, DO, in his book, 'Manual of Osteopathic Technique' written about the manipulative procedures developed by John McManis, DO, in the early 1900's. Since the early 1970's, Dr. Cox has refined the technique; developed a manipulation instrument for effective use of the technique; conducted clinical and experimental research; lectured around the world; and written well-received articles, chapters for textbooks, and textbooks. Cox Flexion-Distraction is a gentle, non-force adjusting procedure that works with the body's natural design to aid it in healing. Dr. Cox has developed a special table for effective use of the technique. The Cox Table (, a Flexion -Distraction table, is used to apply the distractive spinal adjustment. Tractioning the spine and then flexing it can resolve pain from joint and disc problems painlessly. It is a powerfully effective, conservative approach to low back and leg pain, and an alternative to explore before recommending surgery. For patients with non-disc related conditions causing back pain (facet syndrome, spondylolisthesis, sprain/strain, scoliosis, transitional vertebra, sacroiliac subluxation, stenosis), Cox Flexion-Distraction provides all of the above benefits plus the ability to place spinal joints into normal movement to restore spinal motion without pain.

Diversified Technique is the classic chiropractic technique, developed by D.D. Palmer, DC. and taught in all chiropractic colleges. Diversified Technique was refined and developed by the late Otto Reinert, DC, to address biomechanical dysfunction in each section of the spine. The focus is on restoration of normal biomechanical function. Diversified adjusting of the spine uses very precise lines of drive for all manual thrusts, allowing for specificity in correcting mechanical distortions of the spine. Motion palpation and full spine, hands-on techniques are used to deliver a high-velocity, low-amplitude thrust, which makes an osseous (popping) sound as the adjustment is given.

When a patient starts to feel better, we want to ensure that they continue to stay better. To help accomplish that, we design exercise strategies to help keep the body strong and minimize the opportunity for re-injury. Instruction in proper ergonomics is also strongly addressed for the very same reason.

Extremity adjusting is extremely important in the care of all joints beyond the spine. Everything from the fingers to the toes can be injured and become dysfunctional, causing long-term pain and discomfort. These techniques can be employed for the acute injury or the chronic arthritic joint to help in effectively managing those who had always thought or been told they were beyond help.  Even mundane "nuisance" problems can often be fully resolved with very little intervention.

Custom foot orthotics are inserted in the shoes to help relieve imbalances in the feet and body, and help with pelvic & spinal distortion. They are often prescribed for foot problems such as plantar fasciitis, and are useful in the management of many musculoskeletal disorders such as knee pain and lower back pain. We utilize several different manufacturers of flexible, custom-made foot orthotics to ensure the specific needs of the patient are best being met.

Developed by chiropractor Clarence Gonstead over the course of 50 years of practice, this mechanically inclined technique to this day remains a cornerstone of contemporary chiropractic practice. He utilized x-ray analysis, static and motion palpation, spinal thermography, and visualization to ensure he could be as precise as possible in his analysis. Great care is taken to ensure a bio-mechanically correct position and precise thrust to provide the most accurate and painless adjustment possible. Gonstead technique is where the adjustment of the cervical spine while seated first originated.

Graston Technique, developed by athletes, is an innovative patented form of instrument-assisted soft tissue mobilization that enables clinicians to effectively break down scar tissue, adhesive and fascial restrictions. The technique utiilizes specially designed instruments to specifically detect and effectively treat areas exhibiting soft tissue fibrosis or chronic inflammation.

The body's nutritional requirements vary depending on age, activity level, fitness level, environmental pollution, stress levels, and genetics. Nutrition plays a large role in the maintenance of one's health and the capacity of the body to heal. Many times nutritional supplementation is able to aid dramatically in the management of even serious disease. Nutrition also has plays a large part in the maintenance of one's ideal body weight.
