    Integrating IFS and Listening Therapies with Marcella Cox

    02/23/2026 | 41 mins.
    In today's episode, I welcome my friend Marcella Cox back to the podcast.
    Marcella is a certified IFS therapist, approved consultant, and somatic IFS assistant trainer. She's also a certified Safe and Sound Protocol (SSP) and Rest and Restore provider, and the lead author of the new guidelines for integrating IFS with these listening therapies.
    We talk about:
    The basics of polyvagal theory

    How our nervous system states impact our parts

    Why co-regulation is central to healing

    The difference between SSP (connection to others) and Rest and Restore (connection to Self)

    How listening therapies can support safety in the body and allow more Self Energy to emerge

    I also share my own experience trying SSP with Marcella. I experienced some surprising physical shifts and insights that came up after a few short listening sessions.
    If you're curious about nervous system regulation and how it can deepen your IFS work, I think you'll really appreciate this conversation.

    The Courage to Start with the Ending - with Keith Miller and Courtney Corona

    02/13/2026 | 50 mins.
    On today's episode I chat with Keith and Courtney, cohosts of the podcast Tripping Over Love. Keith is licensed therapist and a Level 3 IFS Consultant, and Courtney is journalist and podcaster. They joined me to share their beautiful, messy love story.
    We dive into the courage it takes to start over, the "trauma" of the dating apps, and how they've used Internal Family Systems (IFS) and psychedelics to navigate the "breakups, breakdowns, and breakthroughs" of their relationship .
    We discuss:
    Starting relationships with truth instead of performance.

    Radical transparency — "starting with the ending" — as a foundation for trust.

    Why telling the truth early can save a relationship later.

    Loving someone while still grieving a past life.

    Speaking for parts instead of from them in moments of conflict.

    Finding the courage to try again after loss and heartbreak.

    Dating is messy: Getting honest about the "thrift store shopping" energy of dating apps.

    The difference between loving someone and being "in love."

    IFS as "four-wheel drive": Turning toward the model when relationships get stuck.

    How psychedelic-assisted journeys helped unlock grief — and create space to love again.

    Extended Interview
    At the end of our chat, I asked them each for one piece of advice for couples. This extended interviews is available for paid subscribers over on The One Inside Substack.

    Our Parts Are Angels In Disguise with David Stern

    02/06/2026 | 30 mins.
    On today's episode I welcome my friend David Stern to the podcast. This conversation feels so perfect right now. It's full of the kind of hope we all need. David has this beautiful way of seeing the spiritual dimension in everything we do.
    David calls us to remember our "Pure Soul"—the part of us that is already peaceful and cannot be destroyed. He talks about parts as "angels in disguise," the ones inside that have taken on difficult roles to protect that inner light. If you're looking for a way to stay connected to yourself in a chaotic world, this episode is a sacred reminder that your essence is always already okay.
    We Explore:
    Why David looks for the unbridled aliveness in every person he meets.
    Reimagining our parts as refractions of a primal, divine intelligence.
    How to hold the "horrors" of the world while still choosing to love our people and stay present.
    Practicing "remembrance" to help shift out of the noise and back into your heart.
    About David
    David Stern, Psy.D. is a licensed psycholgoist, certified IFS consultant, dedicated teacher, and the creator of the Thinking Heart IFS Intensive.

    When The World Feels Too Heavy with Daphne Fatter

    01/30/2026 | 34 mins.
    In this episode, I'm joined by my friend Daphne Fatter for a timely and honest conversation about what so many of us are navigating right now, as therapists, as parents, and as humans living in a polarized and chaotic time. We talk about nervous system overwhelm, numb and checked-out parts, news consumption, activism, community connection, and how to stay grounded when things feel "too much." We also touch on Daphne's new book: Integrating Internal Family Systems Interventions into EMDR Therapy.
    In this episode:
    Why so many of us feel numb, frozen, or checked out right now

    Normalizing survival responses and protectors during times of stress

    How polarization shows up both culturally and inside our own systems

    Staying curious about people with different political perspectives

    Finding ways to stay informed without burning out on the news

    Why connection, shared humanity, and community matter so much right now

    I get blended a few times in this episode and say, "I can't believe I said that." This is such a great example of how quickly any of us can blend with passionate and opinionated parts when navigating stressful topics. 
    Be sure to check out my extended interview with Daphne over on Substack.
    About Daphne
    Daphne Fatter, Ph.D., is a licensed psychologist, integrative trauma consultant, author, and international speaker specializing in integrative trauma-informed therapies. She is the author of Integrating Internal Family Systems Interventions into EMDR Therapy and is widely recognized for her expertise in blending parts work with evidence-based trauma modalities.

    Integrating IFS and EMDR with Bruce Hersey, David Polidi, and Joanne Twombly

    01/26/2026 | 51 mins.
    Today I welcome David Polidi, Bruce Hersey, and Joanne Twombly on the podcast to talk about their new book, IFS-Informed EMDR: Creative and Collaborative Appraoches.

    We talk about why this book is needed, what it took to bring together more than 20 contributors, and why integrating these models can create more options, more flexibility, and more hope for clients. 
    We talk about:
    Bringing together 21 contributors and creating a true community project

    Why integration can help when clients get stuck in one modality

    The idea that there is a natural, underlying healing process beyond any single model 

    Coping skills, resourcing, and the diverging views on when and how to use them 

    Joanne's "fire drill" and using IFS to work with therapist countertransference 

    Why strong foundational training in both IFS and EMDR matters before integrating them 

    The belief that there is no "perfect model," and that relationship and Self Energy matter most 

    There's a lot of heart here, a lot of theory, and a lot of love for clients, the field, and each other. I'm excited for you to listen, and be sure to catch my extended interview with them over on Substack.
