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.

Marcella Cox, LMFT, is a therapist, author, and presenter devoted to exploring the intersection of embodiment, trauma healing, and eating disorder recovery. She is a Level 3 Certified IFS Therapist, an Approved IFS Clinical Consultant, and an Assistant Trainer for Somatic IFS, the model developed by Susan McConnell.

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.

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.

• 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.

David Stern, Psy.D. is a licensed psycholgoist, certified IFS consultant, dedicated teacher, and the creator of the Thinking Heart IFS Intensive. He also co-founded IFS Healers, an online Community of Practice designed to foster connection, deepen learning, and build community among IFS practitioners. David has trained hundreds of students worldwide and has presented at the IFS International Conference and consults with practitioners globally.

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.

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.

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.

Bruce Hersey, LCSW is widely recognized for his work integrating EMDR and IFS. Together with Michelle Richardson, he created the Syzygy Institute, which offers training and certification in IIE.

Today's episode is a little different, in a really wonderful way.

I sit down with Dick Schwartz and Jeanne Catanzaro, President and Vice President of the IFS Institute, and partners in both leadership and life. This isn't a traditional interview; it's more like listening in on friends and colleagues talking about the things they care about, the serious, the personal, and the very human.

I've been feeling curious about what's happening inside IFS leadership right now. The model keeps growing, reaching more people, and carrying more responsibility with it. I wanted to hear directly from Dick and Jeanne about what that growth and momentum have been like for them, not just in terms of roles and plans, but personally and as partners.

In this candid conversation, we explore questions many of you have been holding. What happens as the Institute grows? Is Dick going to retire? What does transition even look like? We talk about all of that, but in a funny, sometimes ridiculous, and very real way.

What I hope you hear is the care, thoughtfulness, and humanity behind the scenes of both the IFS Institute and the IFS model.

We talk about:

• Jeanne stepping into leadership and visibility over time

• What it means to steward a model that's bigger than any one person

• Succession, responsibility, and caring for the future of IFS

• Collaboration and "sharing the stage"

• Knowing when to take a break from "parts talk"

• Bringing IFS beyond the therapy room and into the wider world

• Holding research, spirituality, and accessibility at the same time

• Finding balance between work, partnership, family, and rest

• Favorite shows, hobbies, and Firefighter behaviors

There's a lot of warmth here, some laughter, a little potty talk, and plenty of insight.

We all feel numb sometimes. Our numbing parts protect us from stress, pain, and overwhelm. But what happens when numbness lingers?

As we kick off The One Inside's seventh season, Jeff and I share what we've learned about working with numbing parts. We led a workshop at the recent 2025 IFS Annual Conference called Why Check In When You Can Check Out: A Self-Led Approach to Numbing Parts.

In this episode we walk you through the highlights of our workshop and share a few of the insights we brought home from the conference.

We discuss:

• What I discovered about numbness, embodiment, and grief this past year

• Numb parts are "invisible protectors" and why simply naming the numb matters

• The compounding opportunity costs of numbing and what we miss when we spend too much time checked out

• The grief of emerging from numbness

• How numbness shows up across generations and cultures

• The NUMB framework we created for reconnecting with Self

I keep returning to this slide from our deck: Our protectors think they're saving our lives, but sometimes they're quietly stealing our vitality.

I share a lot about my numb season, and how naming the "nothing" became a game-changer. I hope as you listen you'll notice your own ways of checking in and checking out and name the places where numbness shows up for you.

In this episode I chat with Joe Bielling, a Level 3 IFS practitioner, licensed therapist, and co-author of From Broken to Badass. We talk about what happens when coping, adapting, and belonging slowly pull us away from ourselves, and how to find your way back.

Joe shares parts of his personal story, including a period he describes as a mental breakdown and spiritual awakening, and how IFS helped him slow down, notice his parts, and reconnect with his body, heart, and Self Energy.

We discuss:

• Self-forgetting, people-pleasing, and the "chameleon" strategies of belonging

• How Enneagram dynamics show up in relationships and identity

• Unblending as both a psychological process and a spiritual experience

• Why "the resistance is actually part of the path"

• How IFS and non-duality can point to more than either-or thinking

• Why staying "broken" can feel safer to some parts of us

• Gratitude for coping strategies before trying to change them

• The question underneath it all: Who is the one behind my eyes?

Extended Substack Conversation

In the extended interview over on Substack, Joe and I talk about hope, embodiment, trauma, and the Enneagram centers. Joe shares what helps him stay embodied now and where he's finding hope.

In this episode I talk with Anna Christine "AC" Seiple about slowing down, embodiment, and what it means to listen to our bodies and our parts.

AC is a licensed counselor and the author of The Sacred Art of Slowing Down. She lives in St. Andrews, Scotland, where she's working on her PhD exploring the intersection of ancient contemplative practices and modern mindfulness.

She shares why she felt called to write her book, how slowing down was not something she chose at first but something life required of her, and how chronic pain, illness, and unexpected disruptions shaped her relationship with her body. She talks honestly about what it's like to move from living primarily in the head, to slowly rebuilding trust with the body.

Takeaways from this episode:

• why slowing down often happens through life events rather than choice • how disconnection from the body can begin as a survival strategy • the role of self compassion and curiosity when parts resist slowing down • how faith, culture, and early messages can shape our relationship with our bodies • the importance of establishing safety before forcing embodiment • how slowing down and embodiment support parts that have been neglected • what it means to build new "muscle memory" with our nervous systems and parts • how seasons, light, and cycles mirror internal emotional rhythms

I loved how she normalized how hard this work can be, and how she reminded us that slowing down does not mean changing who we are or stopping our lives. This conversation felt especially timely as the year winds down, a time when slowing down can feel counterintuitive.

We continue part of this conversation in an extended interview for our paid community over on Substack, where we talk more about hope, seasons, and what it looks like to live with greater acceptance of where we are.

About Anna Christine Seiple

Anna Christine ("AC") is a licensed counselor, retreat leader, and researcher. She loves cultivating healing spaces that honor the entirety of our embodied beings. She holds two master's degrees, one in clinical mental health counseling and a second in ancient languages and is currently working on a PhD at the University of St Andrews in Scotland, exploring conversations between ancient contemplative practices and mindfulness interventions.

This week I talk with IFS therapist and teacher, Kendhal Hart, about the real-world practice of IFS, how she integrates it with EMDR, and her view of IFS as a neurodivergent clinician.

Kendhal is the author of Treating Trauma with EMDR and IFS, a new book that offers clinicians a practical and compassionate guide to integrating the two models.

She shares openly about her recent autism diagnosis and how her neurodifferences shapes the way she understands, lives, and teaches Internal Family Systems. We explore what it looks like to practice IFS in real time, outside of demos, outside of formal training, and inside the small everyday moments where our parts and Self show up.

We discuss:

• Practical IFS steps tailored for neurodivergent minds

• What's missing in many IFS trainings

• How EMDR complements the IFS healing steps

• Befriending parts before moving to Phase 4 of EMDR

• How to track our internal systems throughout the day

• How to reflect parts and Self back to clients in simple terms

• IFS as a lifestyle

I didn't want this conversation to end. If you love IFS and want a fresh take on living and embodying it every day, in the real world, this episode is for you.
