In this skillfully curated collection, author and clinical editor Jenna Riemersma invites 30 leading IFS experts to discuss how to apply the transformative insights of the Internal Family Systems (IFS) model with a wide range of clients, communities and modalities. Altogether Us opens with IFS founder Richard Schwartz sharing the origin story of the model and describing its remarkable growth. Jenna then presents a never-before published IFS shorthand tool. Each of the following chapters explore the integration of the IFS model with a remarkably comprehensive array of topics including: EMDR, Psychedelic-Assisted Psychotherapy, Somatic Practices, Groups, Polyvagal Theory, Play Therapy, Sandtray, Psychodrama, Addictive Processes, Disordered Eating, Sexuality, Couples, Parents, Adoption, Ancestral Lineage Healing, and the Enneagram. Intersectionality chapters speak to the use of IFS in providing culturally-affirming care to clients with traditionally marginalized identities, including Black, Asian & Pacific Islander, LatinX, Native American, and Neurodivergent clients, as well as clients navigating sexual orientation and gender identity. A powerhouse group of contributing authors, led by Dr. Richard Schwartz, include: Dr. Frank Anderson, Dr. Mona Barbera, Chris Burris, Dr. Sand Chang, Candice Christiansen, Marcella Cox, Dr. Daphne Fatter, Fatimah Finney, Carmen Jiminez-Pride, Mary Kruger, Kathy Mackechney, Meg Martinez-Dettamanti, Susan McConnell, Dr. Suzan McVicker, Dr. Nancy Morgan, Gregg Paisley, Halie Parmalee, Pete Patton LCSW, Leslie Petruk, Patricia Rich, Dr. Alexia Rothman, Joan Ryan, Gaby Satarino, Valerie Simon, Tammy Sollenberger, Julia Sullivan, Cece Sykes, and Regina Wei. Intended for both helping professionals and students of IFS, Altogether Us expands access to this exciting new paradigm in psychotherapy while affirming the vision of Dr. Schwartz to welcome all parts and celebrate diverse and inclusive expressions of Self-leadership in the world.
