The One Inside: An Internal Family Systems (IFS) podcast
My guest on today's episode is Achara Tarfa. She is a certified IFS practitioner, co-founder of the Global Trauma Institute, and director of the PATH program. We talk about finding IFS, what trauma coaching offers that therapy often doesn't, and why she and her co-founders built GTI to create the spaces they needed but couldn't find. Takeaways IFS gave Achara language for her own anger for the first time When the people you turn to for help fail you, the harm compounds. Achara experienced this firsthand and it shaped everything she built Trauma coaching isn't replacing therapy. It's...

On today's episode I welcome Jessica Tomich Sorci to the podcast. She's a therapist, perinatal mental health specialist, and creator of the Mom Parts Method. She's spent 15 years working with moms and noticed the same parts showing up, so she began naming them, then created a methodology and a new book. Her Mom Parts Method is a five-step IFS-based process specifically for mothers. It starts with a meditation to connect with a triggering experience, then moves through naming which parts showed up, speaking truths on their behalf, noticing underlying shame or grief, and identifying what...

Today I welcome to the podcast Drs. Risa Adams, Robin Beardsley, and Elizabeth Parsons. They are family physicians turned psychotherapists who came together during the pandemic to write, find community, and speak for their parts.

Today I welcome Irina Diyankova back to the podcast. Her last episode, was one of our most popular. This time we explore what happens when "going inside" during an IFS session becomes hard for clients. She finds this is especially true with neurodivergent and C-PTSD clients. Irina shares why externalization can be so helpful in these cases. Instead of relying only on what’s happening internally, bringing things outside, like mapping, speaking out loud, connecting visually or relationally, really help. We also talk about how IFS isn’t a cookie-cutter model. We all...

On today’s episode, I talk with Joanna Curry-Sartori, founder of the Self-Leadership Collaborative and author of The Self-Led Educator. We explore this idea of how to bring IFS into everyday life, to invite more Self Energy into our conversations and interactions. Joanna teaches us her PAUSE model, a five-step process to help you slow things down and notice what’s happening inside before you respond. Sometimes it's in moments where you can feel yourself starting to react, or a conversation begins to shift. Instead of pushing through, you pause, get curious about your parts,...

On today’s episode I welcome Nitsan Joy Gordon, a dance movement therapist, IFS practitioner, and peacebuilder who lives in Israel. Nitsan shares about growing up in Israel, living near the border, and what it’s like to live in a place where war and trauma have been part of daily life for generations. She also tells the story of how Internal Family Systems changed her own life. A powerful experience at Esalen with Dick Schwartz inspired her to use IFS in her work back home. Nitsan leads an organization bringing Israelis and Palestinians together to transform pain through deep listening...

On today’s episode I welcome psychotherapist and author Meg Josephson to the podcast. Her book Are You Mad at Me? names something so many of us feel but rarely say out loud: Did I do something wrong? Are you mad at me? Meg and I talk about the fawn response, people-pleasing, and the parts of us that learned early on to stay ahead of conflict. We explore how “being nice” can disconnect us from ourselves, why grief and anger are essential to healing, and how mindfulness helps us slow down enough to notice what’s really happening inside. If you’ve ever swallowed your needs to keep the...
info_outlineToday 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.
