Healing Trauma at the Root
Mercedes Cusick is a Licensed Marriage and Family Therapist, trauma specialist, and EMDR expert based in Los Angeles, California.
Her work is centered on healing trauma at its root not just managing symptoms but addressing the underlying wounds that shape how people live, relate, and survive.
Mercedes specializes in trauma-focused therapy and EMDR, supporting clients who feel stuck in patterns shaped by childhood trauma, relational wounds, addiction, and nervous system dysregulation.
Her approach integrates EMDR, somatic practices, and attachment-based therapy to help clients reconnect with their bodies, build emotional safety, and develop an internal sense of stability that may have never existed before.
In addition to her clinical work, Mercedes mentors and supervises emerging trauma clinicians.
She supports them in developing strong clinical judgment, ethical clarity and the confidence required to do deep trauma work responsibly and sustainably.
A Practice Rooted in Lived Experience
Mercedes didn’t come to this work by accident.
She entered graduate school at 46 years old, driven by a deeply personal calling.
She is in long-term recovery, and her own healing made it impossible to ignore the connection between unresolved trauma, addiction, anxiety, and self-destructive behavior.
Before becoming a therapist, Mercedes worked as an addiction counselor and repeatedly witnessed people being blamed for behaviors that were actually survival responses.
What she saw wasn’t a lack of willpower, it was trauma without support.
She started her practice to do this work differently.
To tell the truth about trauma.
To honor resilience.
And to create a space where healing could happen without shame.
Her work is grounded in lived experience, rigorous clinical training and a core belief: recovery is not about fixing people, it’s about helping them come home to themselves.
Redefining Ethical Care
One of the most challenging paths in Mercedes’ journey has been learning how to balance accessibility with sustainability.
Trauma therapy is deeply needed, and many of the people she serves have never had consistent or affordable access to high-quality care.
Early on, she felt compelled to say yes to everyone to offer sliding-scale rates whenever possible and stretch herself thin in the name of service.
Over time, she had to face a hard truth: a practice that isn’t sustainable cannot remain ethical.
Keeping her business healthy meant paying her mortgage, supporting her family, and protecting herself from burnout so she could continue showing up fully for her clients.
That tension forced her to redefine what ethical care truly means.
Sustainability, she learned, is not selfish. It is what allows care to be delivered with depth, integrity, and presence over the long term.
Growth With Depth
Mercedes’ work sits at the intersection of growth and responsibility.
She offers full-day and multi-day EMDR intensives, mentors and supervises multiple associate therapists, and maintains a full clinical caseload.
Each of these roles requires deep presence, emotional regulation, and a well-supported nervous system.
At the same time, she is working toward her next professional vision: offering equine-assisted EMDR therapy.
This expansion requires significant financial investment, advanced training, ethical infrastructure, and the right conditions to ensure both client and animal safety.
Balancing leadership, intensive clinical work, long-term vision, and burnout prevention is the current edge of her practice.
It’s a challenge rooted not in limitation, but in growth.
Building the Runway
The primary factor slowing that next phase is capacity.
Equine-assisted EMDR requires substantial resources: certification, training, insurance, the right horse, and a facility that meets ethical and safety standards.
Mercedes’ EMDR intensives are the most realistic way to fund that vision, but growing that arm of her practice requires time, bandwidth, and careful pacing.
She knows exactly where she’s headed.
The work now is building the runway, expanding thoughtfully while protecting the quality of her care, supporting the clinicians she mentors, and preserving a life outside of work.
For Mercedes, growth isn’t about speed.
It’s about doing the work the right way and staying well enough to keep doing it.
At Reignelle, we center stories like Mercedes’ to remind us that true healing requires depth, integrity, and care that can be sustained over time.
These are the stories of women who choose to do trauma work responsibly: honoring resilience, telling the truth about survival and refusing to let speed or systems dictate the quality of care.
We believe ethical care includes sustainability, that recovery is a homecoming rather than a correction, and that healing happens when safety is built from the inside out.
Mercedes’ work reflects what we stand for: trauma-informed care rooted in lived experience, leadership guided by responsibility and growth that never compromises presence.
This is healing done the right way with patience, courage, and integrity.
