Humanist Community Center
627 W. Rio Salado Parkway Mesa, AZ 85201


HSGP is a warm and welcoming community of humanists, atheists, agnostics, free-thinkers, and non-theists of all types. The group aims to enrich the lives of any who join us through explorations in science, philosophy, history, and the arts.

We are primarily an educational organization, providing bi-monthly lectures by experts in various fields; opportunities for intellectual discourse over books, arts, and specific discussion topics; and social events such as game nights, potlucks, and special celebrations through the year. Our members have diverse and passionate interests in topics such as separation of church and state, evolution, technology, and environmental issues.

Our community is oriented toward Secular Humanism and provides like-minded individuals the opportunity to share in educational and social activities. We have a playroom and a family bathroom as well as children’s programs, so parents are welcome to bring their children. Please consider joining us, for events that interest you, or as a member of our growing community.

About Humanism (from the American Humanist Association)
Humanism is a progressive philosophy of life that, without theism and other supernatural beliefs, affirms our ability and responsibility to lead ethical lives of personal fulfillment that aspire to the greater good of humanity.

Sunday Speakers Program

The Humanist Society of Greater Phoenix meets twice a month (not quite the same as every other week) on Sunday mornings. Meetings are free and open to anyone who is interested in learning more about Humanism or the speaker's topic.

Doors open at 9:00 AM. We begin by enjoying the company of our fellow Humanists over coffee and breakfast. The program begins at 10:00 AM, when we share announcements and then hear from a guest speaker. Our post-lecture discussions usually end by 11:30, when we invite members and guests to participate in light clean-up chores.

Please note that the Sunday Speaker meetings now have a children's program. For more information see


At our regular Sunday meetings, breakfast is available for a donation of $5.00 or $1.00 for coffee only. Whether you are just coming to hear the speaker or wish to have coffee or breakfast as well, please check in at the welcome desk by the entrance door. Of course, other donations are always gratefully accepted.

Volunteer to help keep our Breakfast Program going! You can volunteer for something easy or you can volunteer for multiple tasks. You can also volunteer for future events. For instructions on how to do that, see the section below entitled "VOLUNTEERING"

HSGP Supports Tumbleweed Center

We make monthly donations of food, clothing, and other basic necessities in support of at-risk youth.

Tumbleweed's Mission is "to serve abused, abandoned, troubled, and neglected youth in our community."

Tumbleweed Center for Youth Development, established in 1972, touches the lives of over 3,000 youth (ages 11 to 22) in Maricopa County annually. They provide emergency shelter, transitional housing, skills development, counseling, education, and other services to develop at-risk youth into self-reliant adults.

HSGP is an Educational Organization rooted in the values of Secular Humanism.

Our speakers' program and various discussion forums are open to all who want to keep their minds stimulated or wish to explore a topic of interest with other Humanists. We demonstrate the people-centric values of Humanism by being a positive influence in the community. We do this through our meetings and lectures (free to the public); community service, such as our support of Tumbleweed Center for Youth Development and the work they do for at-risk youth; and networking with students at campuses throughout Maricopa County to encourage debates and humanistic activities. We affiliate with other groups (including the Freedom from Religion Foundation and Secular Coalition for Arizona) that work to preserve separation of church and state and thereby protecting individual rights.

Our Membership is drawn from a cross section of the Greater Phoenix area. Members range in age from early 20s to 90+, with backgrounds from many professions and walks of life. The only requirement for membership is interest in the principles of Humanism. Participation can be limited to simply attending meetings, or becoming actively involved in projects.

HSGP is an educational non-profit organization. All dues and donations are deductible for income tax purposes.
