Since its foundation, over 150 year ago, Mosaic Lodge #218 has been a beacon to men of all walks of life.
Special traits and aspirations that today characterize our Lodge:
To be a better man, to love his family, to be a good neighbor, to assist his fellow creatures, to serve his community, to honor his country, to promote freedom and justice for all, to sponsor strong education, to support young men and women so they too become good citizens and successful persons, and all this under the auspices of the Supreme Architect of the Universe.
Your interest in Masonry has brought you to the right place. You have just arrived to where your questions about Masonry can be answered by a Mason without prejudice.
Stated Meeting – First Wednesdays of every month at 7:00 PM.
Mosaic Lodge’s mission is to promote personal growth and improve the lives of others. We take responsibility for the well-being of our brothers, our families, and the community as a whole. We value respect, kindness, tolerance, and our differences – religious, ethnic, cultural, generational, and educational, and strive for harmony in our individual lives, in our lodge, and in the global community.
Masonry is a community of men and their families who share similar beliefs and values. The fraternity finds it important to connect with other men of honor, compassion, love, trust, and knowledge, regardless of their race, color, religious beliefs, political views, sexual orientation, physical ability, citizenship, or national origin. We are friends and brothers, and are connected through this vital and uplifting organization of moral men.
Our continuing pursuit of truth, knowledge, ethics, and leadership skills makes us better men and brings more meaning to our lives. Learning the tenets of Freemasonry, paired with being an active part of our community, gives us the opportunity to develop leadership and organizational skills, and builds self-discipline through commitment and self-confidence.
As a member of the Freemasons, the Grand Lodge of California, and Mosaic Lodge No. 218, we are a part of a worldwide organization that values tradition, history, and timeless wisdom. The traditions and core values of our fraternity are meaningful today and will endure for centuries to come because of our direct impact in our community, through our charities, and on a personal level.
Mosaic Lodge membership is open to men 18 and older who meet the qualifications and standards of character and intention, and who believe in a Supreme Being. Men of all ethnic and religious backgrounds are welcome.
One of Freemasonry’s customs is not to solicit members – men must seek membership on their own initiative. Anyone is welcome to request information about the fraternity.
If you are interested in applying for membership to our lodge, now is a good time to start. Please contact us to schedule a visit during an event, or request more information.

Most people know that there are two things that Masons don’t discuss in the lodge room: politics and religion. Instead, they focus on the things that bind them, not that divide. Could that be a model for a more harmonious world outside the lodge?
