Anyone who has been to school can remember at least one teacher whose influ
ence inspired him to learn more fully, to appreciate the subject being taught, and
perhaps to realize a life's work. I have been fortunate enough to have had several
such teachers. In high school, my biology teacher moved me into the sciences, and a
humanities teacher instilled in me the desire to think and reason. While studying
chiropractic, I found Dr. A.L. Logan. I first met him when he voluntarily did clinical
rounds at the Los Angeles College of Chiropractic (LACC).
Roy Logan had a capacity to understand how the human body works, and a curi
osity about it that kept him constantly searching and researching for ways to help
heal it. The profession is full of personalities teaching a variety of techniques, some
insisting theirs is the only way, but it has few true professors who can cull the vari
ous teachings, and present to the student a clear and concise way to approach a
patient, without personality and ego getting in the way. Roy had these abilities, and,
fortunately for us, he had a desire to teach others. He never missed an opportunity.
He saw the need in our profession for a way to link the rote clinical sciences and
the various ways of executing an adjustment. He gave us an answer to the com
monly asked question of when and where to adjust. He was constantly pushing the
profession to realize the importance of effective clinical application of chiropractic
principles at a time when there seemed to be more emphasis on fitting into the health
care industry by wearing a white coat and using big words.
Around the world, students of Dr. Logan use his methods of diagnosis and treat
ment every day and are reminded of his wonderful contributions to the profession.
He lectured repeatedly before several state associations, and taught an eight month
post-graduate course at LACC for eight years. He was Chairman of the Technique
Department at the Anglo-European College of Chiropractic for five years.
In spite of his many contributions, Roy's work remains unfinished. He passed
away in April of 1993, after fighting a terminal illness. He was working hard on his
textbooks up to the end, hoping to transfer as much of his knowledge and wisdom to
paper as he could.
Dr. Logan has a number of students dedicated to continuing his work and seeing
it evolve in the way he envisioned. There is no "A.L. Logan Technique," but rather
a compilation of various teachings, combined with a unique understanding of the
interdependencies of the human structure. We hope to do his work justice and see
more students of chiropractic become as effective as possible in the treatment of
human disorders.
