Mission:

Olive Branch Lodge 38 is a fraternity of freemasons whose mission is to aid and inspire one another to strive every day to control those passions that would control us and improve ourselves that we may each be our own best self for God, our Country, our families, our neighbors, and ourselves.

Vision:

Olive Branch Lodge 38 will be a fraternity of freemasons whose brethren will forever labor in the unfinished work of progressing toward perfection as men and masons. We will examine our own lives and relationships. We will study and apply the lessons taught in the lodge. We will treat people with courtesy and respect. We will exert our talents and give our best efforts to assist in the work of dutiful operation of the lodge and impactful exemplification of its degrees. We will expand "into activity the principles of friendship, love, morality, truth, charity and relief."
