Vitruvius Lodge No. 145

Making true friends,
improving ourselves, having an impact

What is Masonry?

Masonry is the world’s first and largest fraternal organization.  It is guided by the enduring belief that each man has a responsibility to make the world a better place.  For 300 years, Freemasonry has enhanced and strengthened the character of individual men by providing opportunities for fellowship, charity, and the search for truth – within ourselves and the larger world.

Our Mission and Our Lodge

Vitruvius 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.

We meet the second Wednesday of each month at 6:00pm. Location: Vitruvius Lodge, 6640 Bloomfield Road, Petaluma, CA. 94952-9710.  As a lodge, we strive to be an active in our community. We have various charitable and educational events throughout the year, as well as social occasions. Some events are for members only, but many include our families.

Rewards of Being a Freemason

Making True Friends

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.

Improving Ourselves

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.

Having an Impact

As a member of the Freemasons, the Grand Lodge of California, and Vitruvius Lodge No. 145, 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.

Join Us

Vitruvius 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.
