The day-to-day administration and routine temple activities are being carried out by Thrikkalanjoor Sree Mahadevar Devaswom Trust (a family trust consisting of members of Plasthanathu Madhom). Brahmasree Ramaru Vasudevan Potti is the present Chairman and Brahmasree Ramaru Krishnan Potti is the present Manager of the trust. The executive committee members are V. Sreekanth, R. Jithesh, Mithun Krishna and Ramkumar V. Another rarity attributed to this temple is that the members of Plasthanathu Madhom themselves perform the daily poojas.
Major developmental works and renovations were carried out under the aegis of Late Brahmasree Ramaru Raman Potti, former Chairman of the Devaswom Trust. Due to the humble efforts of Plasthanathu Madhom family and the devotees who have contributed magnanimously, the temple has prospered and is well known throughout the state of Kerala, especially around the Travancore belt. Today devotees throng the temple from all corners of Kerala, and other states, to have a glimpse of their deity and offer their prayers.
