Allan is one of approximately 300 practitioners internationally that have attained the Diploma in Mechanical Diagnosis and Therapy from the McKenzie Institute International in New Zealand, the highest level of achievement in the McKenzie method. The McKenzie method emphasizes a mechanical assessment process for spine and extremity disorders, and active patient involvement and education in the management of their treatment. It develops the patient’s self treatment skills in a cost- and time-effective manner while promoting the body’s potential to heal itself without medication, heat, cold, ultrasound, needles, surgery, or a physical dependency on the practitioner. He completed his Diploma training in 1998 and has been a Certified McKenzie practitioner since 1996. He served as the Chief Editor of the McKenzie Institute USA Journal from 1998 - 2005, and was the Chief Editor for the inaugural International Journal of Mechanical Diagnosis and Therapy in 2006.
