This article presents a number of reflections on gerontology pertinence as a professional career, supported on a number of needs and aspects of world and domestic interest, such as: Demographic aging and its consequences; epidemiological transition; social profile of elder population; the challenge of independence; elders role in socialization of younger population, and regulations on matters related to aging and oldness. It is concluded with concern, that before the panorama fully justifying the need of educating professional of gerontology, there is a low offer of undergraduate formation in this field in Colombia, which demonstrates the scarce view of deep transformations and consequences brought, in the middle and in the long term, by the aging process currently faced by our country and the world.
