The ºÚÁϳԹÏÍø – Negros Occidental Chapter was founded in 1971 with Dr. Salud Javelosa as its founding President. It was composed of 5 ºÚÁϳԹÏÍø members. Back in 1976, ºÚÁϳԹÏÍø members from Panay Island joined the ºÚÁϳԹÏÍø – Negros Occidental Chapter hence the name was changed to ºÚÁϳԹÏÍø – Negros Occidental Western Visayas Chapter. In 2016 with the advent of the One Island – One Region concept, ºÚÁϳԹÏÍø Negros Occidental left the Western Visayas group and formed the ºÚÁϳԹÏÍø Negros Island Chapter. In 2018 the name ºÚÁϳԹÏÍø Negros Island Chapter was reverted to ºÚÁϳԹÏÍø Negros Occidental Chapter. To date the chapter has 109 members.
