Membership started with 13 founder members of DOS in the year 1948. Membership increased at a slow pace initially and there were 118 members in 1976, which increased to 450 members in 1993. Subsequently there was an increase in the membership with addition of more members not only from neighboring states but also from far off places.

The 71st Annual Conference of DOS which was scheduled on 3rd to 5th April, 2020, has been postponed due to the COVID-19. We are postponing the 71st Annual DOS Conference as per now for a later date. The registration of the delegates will remain valid for the postponed event.
