Reopening the Window: Ketamine, Psychedelics & The Future of Healing with Sam Mandel
Some people do everything right. They show up to therapy for years, they try the medication, they put in real effort, and the weight stays where it is. Last Wednesday at the District House, a room full of curious, big-hearted people gathered around an idea that speaks to exactly that experience: a window can reopen.
Sam Mandel, Co-Founder & CEO of Ketamine Clinics Los Angeles, joined us for an evening built around that image, and it filled the room with grounded optimism.
Sam opened with a slide presentation walking us through how ketamine works from both the scientific and the experiential side. The central idea is neuroplasticity. At low doses, ketamine can increase the brain’s flexibility, creating a period when emotions become more accessible and new perspectives have room to take shape. For anyone who has felt stuck in the same loop for years, that framing lands.
Sam also walked us through how ketamine is used in clinical settings today, from IV infusions to ketamine-assisted psychotherapy, and where it sits alongside psilocybin, MDMA, and other emerging therapies. He spoke from deep experience. Since co-founding KCLA in 2014 with his father, Dr. Steven L. Mandel, Sam has helped deliver more than 35,000 infusions to over 6,000 patients. That track record gave the evening a steady, evidence-based tone, with plenty of honesty about what ketamine can do and where the field is heading next.
After the lecture, we welcomed a new voice to the District House stage. Kyle Kaplan, our new interviewer, sat down with Sam for his first interview in the role. Kyle brought curiosity and warmth to the conversation, and the format gave Sam room to move from the slides into the personal side of the work: what drew him to mental health care (he volunteered at a teen suicide prevention hotline at twelve years old), what he has witnessed over a decade in the field, and what he sees coming.
Interviews at District House work best when the conversation breathes, and this one did. Congratulations, Kyle, on a strong debut. We’re excited for what’s ahead.
Then it was the room’s turn. The audience Q&A is always a highlight, and this one delivered. Questions about ketamine, healing, and the path between conventional care and the wider psychedelic world came quickly and came from the heart. People asked what they genuinely wanted to know, and Sam answered with the same openness he brought to the stage.
This is what we love most about gathering in person. A question that someone has carried alone for months gets asked out loud, and a whole room leans in because half of them have been wondering the same thing.
Ketamine is one of the clearest bridges between traditional psychiatry and the broader psychedelic movement. It is legal to access in clinical settings today, it has a growing body of research behind it, and for many people it becomes the first step toward a new relationship with healing. Evenings like this one help the community understand that bridge: what it offers, how it fits with other tools, and how to approach it with eyes open.
That is the heart of District216. We bring thoughtful practitioners, honest science, and a room of curious people together, and we let the conversation do its work. Whether you walked in new to this space or already deep in it, we hope you left with a clearer map and a few new friends.
Every Wednesday at the District House brings another voice, another conversation, and another chance to find your people. Come ask your questions in person. Your healing matters, and so does your community.
With gratitude to Sam Mandel, Kyle Kaplan, and everyone who filled the room. 💜
