American Board of Obesity Medicine - Certified Diplomate

Dr. Harry J. Lefebre, M.D.

Dr. Harry Lefebre’s personal interest in weight control began as an overweight child. He has nurtured his interest in obesity treatment (Bariatrics) throughout his entire medical career.

Dr. Lefebre founded the Lefebre Weight Control Clinic in March of 1988. Before then, he practiced family medicine from 1974 -1985 in several South Calgary communities extending from Acadia to Midnapore. He moved to Texas in 1985 to pursue his interest in Bariatric Medicine.

“Bariatric Medicine is the medically supervised treatment of obesity and its associated conditions”. The term was derived from the Greek word “weight” and was coined by several interested physicians in the USA in 1950. In that year, they formed the American Society of Bariatric Physicians (ASBP). Dr. Lefebre has been a member of the ASBP since 1983 and has also been a member of the Canadian Obesity Network (CON) since its inception.

Dr. Lefebre (in 1990) became the first physician in Canada to obtain Diplomate status with the American Board of Bariatric Medicine (ABBM). The ABBM was established to serve the public and the field of bariatric medicine through the establishment and maintenance of criteria and procedures for examination and certification of physicians who seek recognition of their accomplishments in bariatric medicine. The ABBM advocates a comprehensive, multi-faceted approach to the treatment of obesity. Diplomates must satisfy the qualifications for certification, pass a certification exam, complete a board inspection, participate in continuing medical education, and are recertified every five years.
