IFS Talks

We are excited to celebrate the launch of IFS Collected Wisdom: Conversations with Experienced Voices in Internal Family Systems a book that brings together voices, reflections, and lived experience from across the IFS community. This book was created from a desire to honor those voices, and to acknowledge that wisdom in IFS doesn’t live in one place or one person. It lives in relationship, in experience, and in the field as it evolves. Thank you for being a listener, for being part of this community, and for continuing to explore what becomes possible when Self leads. We hope that IFS Collected Wisdom can become a companion in your IFS journey. Here is a link to the IFS Collected Wisdom book contents.

The Role of Uncertainty in Mental Health with Sarah Bergenfeld and Martha Sweezy
In this episode, we welcome two leading voices in Internal Family Systems therapy for a conversation that bridges neuroscience, sensory experience, and healing. Sarah Bergenfield is a certified Level 3 IFS practitioner, writer, and educator specializing in autistic individuals and couples. Autistic herself, Sarah weaves together IFS, polyvagal theory, predictive processing, and sensory science in her clinical and consultation work. She teaches internationally for clinicians working with neurodiverse clients, and her work reframes autism not as a deficit, but as a condition of sensory surplus. Martha Sweezy is an assistant professor of psychiatry at Harvard Medical School, program consultant and supervisor at the Center for Mindfulness and Compassion at Cambridge Health Alliance, and a psychotherapist in private practice in Northampton, Massachusetts. She teaches IFS nationally and internationally and has authored and co-edited numerous books on the model, including Internal Family Systems Therapy, Second Edition (with Richard Schwartz), Intimacy from the Inside Out (with Toni Herbine-Blank), and Internal Family Systems Therapy for Shame and Guilt.
Together, Sarah and Martha are co-authors of Wired to Feel: Autism as a Condition of Sensory Surplus.
In this episode, we explore the role of uncertainty in mental health: how it can quietly drive distress and shame, and how IFS offers a path toward resolution. While the conversation has special relevance for autistic systems, the insights apply across all neurologies.

In this episode, we explore the nature of grief through the lens of Internal Family Systems (IFS) with senior trainer Einat Bronstein. Drawing on the work of Francis Weller and other key grief theorists, we reflect on grief not as a problem to solve, but as a deeply human experience that calls for presence, witnessing, and integration.

We discuss how cultural expectations and “collective burdens” shape the way grief is experienced, often leading to blocked or frozen processes. From an IFS perspective, grief is understood as a complex, non-linear experience carried by different parts of the internal system, particularly exiles.

The conversation explores topics like:

How IFS differs from stage-based and task-oriented models of grief - such as those of Elisabeth Kübler-Ross, John Bowlby, J. William Worden, and Robert Neimeyer
What happens internally when we experience loss, and the roles of different parts in the grieving process
Why grief may feel stuck, and how Self-led witnessing can allow transformation and healing
The connection between present grief and earlier, unresolved losses
The role of psychoeducation, ritual, and embodied expression in supporting grief
What it means to “integrate” a loss within the IFS framework

We also reflect on common pitfalls therapists may encounter when working with grief, and the deeper wisdom that can emerge from loss, about love, attachment, and the enduring presence of those we have lost.

This episode is an invitation to approach grief with curiosity, compassion, and openness, honoring it as a doorway to connection, meaning, and inner transformation.

Our guest is Paul Neustadt, a clinical social worker and IFS Senior Co-lead Trainer. Paul has worked in community mental health and the counseling program of a working-class state university as well as having been the director of a community-based counseling and prevention program. Paul sees himself as a spiritual being in a human body, on a healing journey, in this life to learn lessons, to connect with his soul, and to live in accordance with his life purpose. Part of his life purpose has been to share the gift of IFS with others. In this episode, we discuss the qualities and virtues of Self-like parts, and how to welcome, honor, and genuinely validate them in a non-shaming way that allows more Self energy to emerge.
