San Dimas Lodge No. 428

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

San Dimas Masonic Lodge #428
San Dimas Masonic Lodge exists to develop and uphold the principal tenets of Freemasonry: Brotherly Love, Relief, & Truth.  We are a brotherhood of men from all backgrounds who place a high value in supporting our community.  We hold in high regard the ancient ceremonies and degrees of Freemasonry passed down through the generations, and preserve them for future generations to come.
San Dimas Masonic Lodge No. 428 was established in 1911 by 20 local Masons who met at the Foresmans & Hoke Hall, developing over the last 100+ years into a strong brotherhood of currently over 100 San Dimas Freemasons.

Masonic news

A Masonic Whodunnit

In September, NBC’s streaming service, Peacock, debuted a new television adaptation of Dan Brown’s The Lost Symbol which touched off a sudden explosion of interest in Freemasonry and provided a mysterious backdrop to the plot of the story.

California Freemason: The Music Issue

In this special issue of California Freemason Magazine, we delve into the unique power of music—the power to heighten the ritual, to find and make meaning, and to bring people together.

Worth the Trip

As master of his not-so-nearby lodge, Barstow Boron Lodge 682, Miguel Vazquez makes the long trip into the Inland Empire numerous times each week to sit in the East. Still, you won’t hear him complain. Neither will the other 122 members of the Masonic lodge.

Eye of the Beholder

Could a hiding-in-plain-sight Masonic icon change the way we understand a Diego Rivera masterpiece?

Spanning the Divide

For many lodge leaders, navigating the tangles of intralodge conflicts and beefs isn’t just challenging—it can feel totally outside their skill set. Yet a lodge master’s greatest responsibility isn’t just balancing the books or organizing events; it’s maintaining lodge harmony.

Past Present

When Bob Sachs first peered inside the vault in the basement of his lodge hall, he wasn’t totally sure what he was looking at, but there, wrapped in canvas, was a five-foot-tall painting of George Washington dressed in a Masonic apron.

Pyramid Scheme

What started as an idea to turn a quick buck on a national holiday morphed into a million-dollar idea for North Bay Mason Jim McCullough.

Trust Fall

During lockdown, the usually reserved Rio Santonil was compelled by an urge for action. And so, in September, he resolved to fulfill a lifetime goal and go skydiving. And then he did it again. And again. And again.

A Second Home

Fraternal organizations played a historic and civic role within Filipino American communities. Learn more about the rapid growth of Fil-Am Freemasonry.

California Freemason: The Filipino Issue

In the latest issue of California Freemason, we explore that special bond and celebrate the many ways Filipino American Masons have and continue to strengthen the fraternity.

An Absolute Corker

Shrouded in equal parts mystery and merriment, Ye Antient Order of Noble Corks is a bit of an outlier even within the sometimes bewildering world of Freemasonry.

At Refreshment

A curious thing happens at the close of many Masonic lodges. Drinks are poured. Glasses clink. Mirth swells. The lodge is “at refreshment,” an important if unofficial custom that encapsulates so much of what #Freemasonry is all about.
