When OBI started operations, village projects including kindergarten schools for the poor were set up. Oscar Arellano asked Ambassador Preciosa S. Soliven to manage these schools. OBI assisted in the fundraising that initially financed the O.B Montessori Center making it self-supporting until its incorporation in 1975. Amb. Soliven assumed the presidency of this non stock, non profit institution. The original board members were SEC commissioner Angel Limjoco, Sen. Salvador Laurel, Greek Counsel General Alexander Adamson, Sony Philippines President Elena Lim and Philippine Star publisher Max Soliven.
