The Third Annual Health Conference presents the theme “Your Health Thrives in Community,” exploring how meaningful relationships and supportive environments contribute to whole-person health. April 24-26, 2026.

In a time when the loneliness epidemic in America is increasingly recognized as a major public health concern, this conference will examine the powerful role that connection plays in strengthening physical, emotional, and spiritual well-being. Our speakers will address topics such as social connection and emotional resilience, nutrition and lifestyle habits, the paradox of social media, and practical ways to cultivate healthier communities and relationships.

Participants will gain valuable insights from health professionals and experienced presenters who will share research-based knowledge, practical tools, and strategies to promote lasting wellness.

All conference sessions are free to attend; however, registration is required to help us plan seating, materials, and meals. A healthy lunch will be provided on Saturday for registered participants.

The weekend will also include a Sunday 5K Walk, encouraging attendees to enjoy physical activity together while continuing to build community.

Registration is available for both the conference and the children’s program, allowing families to participate while younger attendees enjoy engaging, age-appropriate activities at https://www.sapreventivehealth.org

Join us for a meaningful weekend of learning, encouragement, and connection as we discover together how health truly thrives in community.

Trinity University’s Department of Human Communication and Theatre closes its 60th theatrical season with NOT EVERY MOUNTAIN, created and presented by Stieren Guest Artists Rude Mechs as part of the Stieren Arts Enrichment Series. Performances run April 23, 24, 25 at 8:00pm and April 26 at 2:00pm, in the Stieren Theater of the Ruth Taylor Theater Building. Admission is free, and seats are limited. Reservations are available at https://tumountain.eventbrite.com.

NOT EVERY MOUNTAIN is a mellow meditation on change, permanence and our place in the natural world. It is a presentation of the life cycle of mountains and the processes by which they are born and eventually laid to rest, an invocation of tectonic force and geologic time. Using string, cardboard and magnets, NOT EVERY MOUNTAIN invites us to watch the collective effort of making and unmaking a series of interlocking mountain ranges. We watch minutes, or perhaps centuries, unfold, as mountains rise and fall, clouds dance, birds alight and depart, and a moon delicately hangs overhead. NOT EVERY MOUNTAIN features music and sound created using earth’s most prominent natural frequency, The Schumann Resonance, and is underscored by a poetic recitation—or perhaps a spiritual incantation.

Opening Reception for Eric O'Connell's Pinhole Photography Exhibit is on March 29, 2026 at 3:00 PM.

The show opens March 22, 2026 through May 27, 2026, and presents creative pinhole portraits of San Antonio Artist immersed in their artform.

The opening exhibit of Eric O’Connell’s pinhole photography invites viewers into a living moment where time, movement, and memory converge. Through long exposures that compress minutes into a single frame, O’Connell reveals portraits that are both sharp and softly obscured, capturing not just a subject’s image but the interaction, motion, and atmosphere surrounding them.

Ghostly blurs, shifting shadows, and layered spaces create a sense of transparency and connection, allowing creativity, place, and presence to merge into one unified view. This exhibit asks audiences to slow down and consider the fleeting, often overlooked relationships between time, the artist, and the world they inhabit.

As the Edwards Aquifer Authority (EAA) celebrates 30 years of stewardship on June 28th, we invite residents, students, businesses, and organizations from Atascosa, Bexar, Caldwell, Comal, Guadalupe, Hays, Medina, and Uvalde counties to help us look to the future by showcasing how you're managing the drought. Whether you're collecting rainwater, composting, using drip irrigation, or embracing native plants—we want to see it!

Winning photos will be featured in the 2027 EAA Calendar, celebrating innovation, resilience, and the community’s shared commitment to protecting the aquifer.
