"Making good men better."

Freemasonry is the oldest and largest fraternal organization in the world. The Masonic experience encourages members to become better men, better husbands, better fathers, and better citizens. Masonry use the tools and implements of ancient arhitectural craftsmen symbolically in a system of instruction designed to build character and moral values in its members. Masons are men of good character who strive to improve themselves and make the world a better place.

The origins of Freemasonry have been lost to history, but modern Masonry dates back to 1717 in England. It quickly made its way to the New World, and many of our Founding Fathers were brother Masons. Masonry has been a part of Montana's history since its modern beginnings. Both Lewis and Clark were Masons. The first recorded Masonic meeting in Montana was held in 1862, the first Lodge was chartered in 1864, and the Grand Lodge of Montana was formed in 1866. Sentinel Lodge 155 was founded in 1960 due to the abundance of members in the other Missoula-area lodges.


Sentinel 155's twice-monthly lodge meetings are the foundation of our fraternity. We come together as equals, meeting on the level as brothers to improve in our knowledge and practice of freemasonry. We enjoy brotherly love and fellowship, lead our newest brothers through the rituals of our degrees, and share education in the ancient wisdom of our order.

Sentinel meets on the 1st and 3rd Wednesdays of every month.


Each year Sentinel Lodge 155 participates in community and charity events. Supported by the Grand Lodge of Montana, we raise funds throughout the year to engage with and serve the Missoula area community! This years events are calendar sales to support the Shriner children's hospital and cookie bakes to be delivered to our long term care facilities.



The Masonic brotherhood is about building relationships.  We promote and foster this through various forms of fellowship.  Besides the stated meetings the lodge puts on formal dinners, bbqs, bowling nights, and various other activities. Come join us!
