IFS Community

About IFS Healers

Where inner work meets community.

IFS Healers was born from a simple truth: doing transformational work alone isn’t sustainable.
We need each other.

Post-COVID, in a world of Zoom fatigue, polarization, and endless online noise, we wanted something different — a space that felt real.

A space that prioritized connection, humility, and embodied healing.

IFS Healers began as a small circle of practitioners committed not just to learning the IFS model, but living it. That circle grew. And kept growing.

Today, we are a living, evolving community of coaches, therapists, nurses, spiritual guides, artists, and more — each integrating IFS into our lives and work.

We are united not by profession, but by practice.

Our Roots: Toni & David

IFS Healers was co-founded by Toni and David — longtime practitioners, facilitators, and teachers in the IFS world.

They created this space not as an extension of a training program, but as a community laboratory — a place for us to try things, learn from mistakes, co-create rituals, and build sustainable healing culture.

They brought clarity of vision, big hearts, and deep trust in the intelligence of the collective.
That ethos lives at the core of everything we do.

What Makes Us Different
We’re experiential by design

Everyone here has had some kind of IFS practice experience — not just intellectual study. You don’t need to have taken our courses, but you do need to show up ready to be present, real, and in process.

We’re not a guru culture

We believe in skill and wisdom — and we share it generously. But hierarchy isn’t the vibe here. Every member has something to offer. We’re here to lift each other up.

We grow our own leaders

You don’t need to be “certified” to lead. If you’re walking the walk and want to guide others, we’ll support you in stepping into PA roles, teaching, or co-facilitating your own work.

We repair what breaks

Real community involves rupture. And repair. We’re proud of our agreements and the structures we’ve built for holding conflict and staying in connection.

This is a community of practice
Not a club, not a brand, and not a training factory.
It’s a home for people doing real work.
And we’re glad you’re here.

Meet the Team

David Stern

My name is David Stern, I’m a licensed psychologist since 1992, trained in EMDR, Brainspotting, and I am a Certified Internal Family Systems (IFS) consultant.

I have been teaching this model for the last 10 years.

WHAT I DO

I help people connect with their inner vitality and the primordial wisdom in which they and we all are drenched.

I help people work with the obstacles, parts and patterns that, in their effort to protect and serve the system, mute, obscure, or warp the very vitality and wisdom they are committed to protect and serve. They too are expressions of that deeper wisdom and vitality. Together we will transform your relationship with these so that their hidden genius, and the buried treasure they carry can become a glorious part of your life and the life of your communities.

Increasingly, my work, teaching, and my spiritual practice is informed by ancient and contemporary non-dual contemplatives. As I grow, my healing practice is informed and transformed by said growth.

WHO I AM

My undergraduate studies included a focus on music, and an obsessive exploration of philosophy and mystical theology.

After a number of years playing music in various bands throughout the great northwest, I returned to graduate school and got my doctorate at the Massachusettes School of Professional Studies (now, William James College).

I’m a licensed psychologist since 1992, trained in EMDR, Brainspotting, and I am a Certified Internal Family Systems (IFS) consultant.

I am also a husband since 1988, and a father of two wonderful and wonder-filled children. I play the saxophone and clarinet and sing.

For many years, I co-led a monthly drumming and chanting service at Temple Emanu-El. As part of a larger contemplative prayer sub-community, this service has been going on since 1996 or so.

My office is in Providence Rhode Island where I have a busy psychotherapy/consultation/teaching/healing practice.

Toni Rosati

I’m Toni Rosen Rosati, co-founder of IFS Healers.

I’m an Allied Mental Health Professional and NBHWC credentialed coach. I’m a Level 3 trained IFS Practitioner who’s been dedicated to the Internal Family Systems (IFS) model since 2021.

I earned my Masters degree in my 30s when I decided to close my photography business and make the “ridiculous” career change to climate data scientist. 

As an intersectional scientist, I’ve never fully fit into an existing box. But psychology,  perception, and how we make decisions have always been important to me. Once I learned about my AuDHD (in my 40s!), the world made a lot more sense!

A bit more about me:

I am based in the Denver/Boulder area and use IFS as my main modality. I have completed Level 2 with Ann Sinko and Mike Elkin, Level 2 Deepening training with Stephanie Mitchell, and Level 3 with Pam Krause. I’ve had the honor of being a PA at the Institute for Level 1 and Level 2 six times. I ADORE teaching, mentoring, and coaching. 

My identities include being raised female, Adult Child of an Alcoholic, child of an adoptee, and grandchild of an Auschwitz survivor. I am happily child-free with a wonderful partner, two dogs, and two cats. 

Some of my identities are: tomboy, nerd, gardener, wig maker, and watercolorist.

I was diagnosed with ADHD in my 40s – which explains my career changes! I’ve been a professional photographer, climate and society scientist, data curator, and UX researcher. In my private practice I focus on confidence, creativity, and living congruently.

Stephanie Mitchell

My name is Stephanie Mitchell and I’m a Certified Level 3 IFS Therapist working in private practice in Australia

Stephanie is a Certified Level 3 IFS Therapist. She is interested in how healing and change occur in the human-to-human relationship, within spaces of safety and acceptance and outside the constructs of diagnostic labels.

Stephanie has worked in mental health services for the past 15 years, beginning her life as a therapist working with clients diagnosed with “BPD” or “Schizophrenia”.

Stephanie has co-facilitated Hearing Voices groups, trauma therapy groups and trained therapists across the world on working with psychosis. 

Stephanie is currently undertaking research on IFS and psychosis with the University of California, San Francisco and Flinders University.

Stephanie has worked with many of the leading people in the psychiatric survivor’s movement including members of ISPS, A Disorder for Everyone, Drop the Disorder, and Mad in America. 

Stephanie is well position to offer this training because of her own deep healing with IFS.

Having a tenacious system of parts who have been dedicated to ‘full healing’ of her extensive early developmental, trauma, neglect and abuse, she has undertaken over 700 hours of her own IFS work with a senior IFS Practitioner.

Stephanies embodies the grounded energy that is possible when our parts allow us to go to their core wounding and unburden.

In this course Stephanie briefly shares her own experiences of transference enactment, unbearable times of feeling “crazy”, and how she made it out the other side to a Self-led life that is deeply connected to her parts.

This course is enriched by significant academic rigor and the student is invited to take both a deep dive into the research and then allow that to stay on the side of their therapeutic work as they move to a right-brained connection to their clients.

Sigrid Kulkowitz

I’m Sigrid Kulkowitz, a Certified IFS Therapist, Consultant, and Clinical Supervisor.
I’ve been a licensed Marriage and Family Therapist for 14 years and have focused on IFS for the past 9, assisting in multiple Level 1 and 2 trainings and offering consultation to individuals and groups.

I’m Sigrid Kulkowitz. I’m currently 66 years young and live in upstate NY with my husband in a community of about 250 residents. I have been a licensed Marriage and Family Therapist for 14 years. The past 9 years with a focus on learning and practicing Internal Family Systems (IFS). After my own Level 1 and 2 training, I became a program assistant for several Level 1 and 2 trainings for the IFS Institute as well as assisting twice for Dick Schwartz. I became a Certified IFS therapist, consultant, and clinical supervisor 4 years ago. Along the way I have taught IFS introduction courses as well as done IFS consultation for both individuals and groups of therapists. Some would say I kind of eat and breathe IFS.

I love people and have a long history of working with them as a coach, acupuncturist, midwife assistant, and crisis counselor. I’ve also been a baker, waitperson, house cleaner, artist and dancer. 

I love turning others onto IFS. To me it is a particularly beautiful and hopeful model for working with trauma. My work focuses on supporting my clients in healing their injured parts and therefore their relationship with themselves and others. 

In my own inner work, IFS afforded healing in my system that I never had been able to experience before (thank you, Derek Scott!). I understand and am indebted to this model from the inside out so it is an honor and privilege to support this journey for others.

Sylvia Schyberg

I am a Licensed Clinical Social Worker (LCSW) and maintain a private practice in Colorado Springs, CO. I specialize in working with individuals wanting IFS therapy or consultation, and love mentoring other professionals, with their own healing or in consultation, to get their license, or to continue in their IFS journey.

Who I am professionally
I am a Level 3 trained, Certified IFS Therapist and IFSI Approved Clinical Consultant. I have PA’d in trainings by the IFS Institute too many times to count, and especially enjoy helping others become an assistant themselves. Through my own IFS journey (since 2017) I discovered my passion of mentoring others to become who they are meant to be as an IFS practitioner.
In my over 20 years experience working in the mental health field, I worked with a broad spectrum of of situations, such as behavioral and emotional concerns, anxiety, cultural difficulties, military life issues, adoption and attachment issues, child development, parenting gifted and spirited children, spiritual questions and healing and of course trauma.
I attended community and tribal college in Washington State, and am a graduate of Auburn University and the University of Alabama. Further, I received a Certificate in Animal and Human Health Connection from Denver University. In terms of non-western healing, I also provide energy and sound healing, use intuitive shamanic techniques, and am clairsentient and claircognizant.
I have run a variety of successful consultation groups, have presented at conferences and general audiences speaking on various topics. Being a therapist is my second career.

Who I am personally
I was born and raised in Germany, and moved to the US after marrying a service member who is now retired. We have one biological child in college, and 2 adopted children (one in college and one finishing high school), as well as one dog and 2 cats. In another life I would have been a dragon rider.
Through IFS I discovered my own neurodiversity and am now ok with not fitting in anywhere. I love the ocean and the forest, astrology and music, reading and dancing, puzzles and tarot, and love discussing anything mystical and out of the box.

My Approach
I consider myself to be an interactive IFS therapist, or actually, a holistic healer. I integrate complementary methodologies and techniques if that’s what you would feel comfortable with.
Body, Mind, Spirit, and Emotion cannot be separated. We often attempt to heal one area, or use our intellect to manage our emotions, and find ourselves wondering why we keep doing the same things, or why we are still dealing with the same things.
My intention is to lead with compassion and understanding, in order to empower you and build on your strengths to attain your personal goal.
As a Social Worker and human being, I strive to be socially conscious, and am committed to continue my own understanding in cultural and ethnic diversity, while being aware of my own privilege and limitations. I strive to help end discrimination, oppression, poverty and other forms of social injustice through public education and social justice advocacy.
