Making Safe Water Accessible: Social Innovation with Purpose with Lieselotte Heederik – Walk Talk Listen (Episode 200)

In this milestone 200th episode of Walk Talk Listen, Maurice Bloem is joined by Lieselotte (Lisa) Heederik, co-founder and CEO of Nazava Water Filters, an award-winning social enterprise working to provide safe, affordable drinking water to low-income households across the Global South. Lisa shares her personal journey—from a childhood across Bolivia, Kenya, and Yemen to leading one of the only WHO-certified water filter companies in developing countries. Her own experience of dehydration as an infant shaped a life-long mission: making safe water a right, not a privilege.
 
During this wide-ranging conversation, Lisa reflects on how Nazava scaled its impact to reach over 600,000 people in 30+ countries. From the post-tsunami landscapes of Aceh to microfinance-driven solutions in Kenya, she discusses the intersection of women’s empowerment, climate action, and health equity. With humor and humility, Lisa shares her “why,” what keeps her hopeful, and how running trail races mirrors her work as a purpose-driven entrepreneur.

From Geoscience to Systems Change: Coaching for a Better Future with Gideon Lopes Cardozo – Walk Talk Listen (Episode 199)

“Google the name of the disease my daughter has.” With that sentence, Gideon Lopes Cardozo shared about a deeply personal part of his life—his daughter’s diagnosis with 22q11.2 deletion syndrome, a lesser-known yet relatively common chromosomal condition. In this honest and wide-ranging conversation, Gideon shares how his path led from Earth sciences to executive coaching, team dynamics, and systems thinking.
Over two decades, Gideon worked internationally as a geoscientist in academia and the energy industry before shifting toward organizational transformation. He now supports teams in the energy transition space using relational systems coaching and agile methods. Maurice and Gideon explore what it means to navigate complexity—whether in personal life or global systems—with humility, empathy, and curiosity.

Religion in the Public Square: Literacy, Dialogue, and Ancient Roots with Chip Gruen – Walk Talk Listen (Episode 198)

In this episode of Walk Talk Listen, Maurice Bloem is joined by Dr. William “Chip” Gruen, Professor of Religion Studies and Director of the Institute for Religious and Cultural Understanding at Muhlenberg College. With a PhD in Religious Studies from the University of Pennsylvania and a scholarly background in early Christianity, Chip’s passion has evolved toward enhancing religious literacy and fostering deeper public discourse on religion. He shares how his academic roots influence his current public-facing work, including the ReligionWise podcast and educational programs designed to help people speak about religion with more nuance and understanding.
Chip reflects on how ancient narratives still inform modern identity, how religion continues to shape public life, and why better dialogue matters in divided times. With humor and depth, he speaks about the role of curiosity in confronting complexity, and how the Institute’s work invites both students and the wider public to engage religion not as dogma, but as cultural expression. He also shares insights on inner growth, music, kindness, and the power of simply listening well.

Sacred Spaces and Growing Edges: Teaching Religion to Kids with Vicki Garlock – Walk Talk Listen (Episode 196)

In this episode of Walk Talk Listen, Maurice sits down with Rev. Dr. Vicki Garlock—founder of World Religions for Kids, award-winning author, and editor of the Religion Matters blog. Vicki shares her journey from a background in neuroscience and cognitive development to creating engaging, multifaith educational materials for children ages 3–10. Drawing from her upbringing in Lutheran and Catholic settings, her years as a professor, and her work at Jubilee! Community, Vicki reflects on how early experiences, academic rigor, and spiritual curiosity shaped her path.
In this conversation, Vicki discusses what it means to teach religion in age-appropriate ways, her thoughts on being an “amateur mystic,” and how her books We All Have Sacred Spaces and ABCs of the World's Religions are helping young people (and adults!) explore religious literacy with empathy and wonder.

Following Curiosity and Embodied Expression with Sofia Sayabalian – Walk Talk Listen (Episode 194)

In this episode of Walk Talk Listen, Sofia Sayabalian opens a thoughtful conversation on the intersections of creativity, communication, and connection. With warmth and insight, she walks us through her Armenian roots, her journey from Los Angeles to Seattle, and her evolving relationship with spirituality, identity, and purpose. Maurice and Sofia explore how storytelling—especially in the digital age—can still uphold human intimacy, even when mediated by emerging technologies like AI.
 
Sofia shares the inspiration behind The Power of Dance, her graduate audio storytelling project that blends narrative vulnerability with interviews from fellow dancers. She reflects on how dance becomes a vehicle for healing, grounding, and creative expression—an extension of the artistic spirit she nurtured through painting and mindfulness. The episode also touches on imposter syndrome, the importance of listening, and why developing a relationship to self is essential for making meaningful impact in the world.

My Church Is the Music with Chelsea Baratz – Walk Talk Listen (Episode 193)

In this episode of Walk Talk Listen, saxophonist, composer, and community builder Chelsea Baratz takes us on a deeply personal journey through music, mentorship, and meaning. Raised in the soulful, hard-bop heart of Pittsburgh and sharpened in the creative fire of New York City, Chelsea reflects on formative moments—from her first jam session at the Crawford Grill to the life-changing mentorship of Sean Jones and Roy Hargrove. We explore how her upbringing, identity, and powerful experiences shaped both her artistry and her ongoing recovery from COVID related challenges.
 
Chelsea also shares her role in boundary-pushing projects like the all-female HERA Collective and The Empress, her recent top-charting saxophone quartet. As she discusses the Sustainable and Inner Development Goals, Chelsea makes a compelling case for art as a form of activism and connection. From invoking the Akashic Field to advocating for communal care and restorative justice, Chelsea’s voice rings clear: music is not only her sanctuary—it’s her way of making the world better, one note at a time.
