Our outer worlds are complex.
So are our inner worlds.

A little understanding can help you navigate both.

All Parts Welcome is a resource for anyone looking to have a more compassionate understanding of themselves and others and who want to find new ways to decrease their anxiety, depression, relationship challenges and address their trauma by engaging in parts work.

All Parts Welcome is about evolving the way we relate to ourselves, our parts, others and the world so that we can be liberated from the old narratives that no longer serve us.

Mariah Rooney, MSW, LCSW (she/they)

After her time at the world-renowned Trauma Center in Boston, as well as teaching graduate-level courses in parts work and leading trainings across the US and online featuring parts work approaches in psychotherapy, Mariah is bringing her rich experience with the modality to life through All Parts Welcome’s self-paced framework.

Combining her comprehensive experience as a therapist and as an instructor, Mariah created All Parts Welcome for individuals seeking a better understanding of self and for professionals who want to learn how to use parts work with clients through in-depth trainings, consultation and community.
