Synergetic Play Therapy

Synergetic Play Therapy (SPT) is a research-informed model of play therapy that blends the therapeutic powers of play with principles from nervous system regulation, interpersonal neurobiology, attachment theory, physics, mindfulness, and therapist authenticity.

Synergetic Play Therapy (SPT) is a research-informed model of play therapy that blends the therapeutic powers of play with principles from nervous system regulation, interpersonal neurobiology, attachment theory, physics, mindfulness, and therapist authenticity.

What is Synergetic Play Therapy?

Developed by Lisa Dion in 2008, SPT emerged from both clinical experience and key research in neuroscience, Interpersonal Neurobiology, and attachment theory (see Badenoch, 2008; Porges, 2011; Schore, 1994; Siegel, 1999). Preliminary research has shown that SPT can significantly enhance a child’s capacity for emotional regulation and tolerance (Dion & Gray, 2014; Simmons, 2020).

More than a model, SPT is a way of being in relationship with oneself and others. Its principles are universal and can be integrated with any existing therapeutic approach—or used as a foundational framework. SPT includes both directive and non-directive elements, allowing flexibility to meet the individual needs of the child and therapeutic context.

What Makes SPT Unique?

Introduction to the Treatment Model

The term “Synergetics” (from physicist Buckminster Fuller) describes how systems transform through dynamic interaction. In the playroom, this principle is mirrored in the relational process between therapist and child. Healing happens not in isolation, but through a “synergy of systems” where internal and external regulation co-exist.

By first attuning to their own internal state and then to the child’s, the therapist creates a synergetic field where co-regulation becomes possible. Through this right-hemisphere-to-right-hemisphere communication, integration and transformation begin. New neural connections are formed, paving the way for lasting change (Dion & Gray, 2014).

SPT is built on three pillars:

The Philosophy of SPT

In SPT, the therapist is the most important toy in the playroom. The toys become tools to help:

But in SPT’s truest form, toys and language aren’t required. What matters most is the emotional energy and the perceptions being expressed through play.

SPT views the therapist as an external regulator who helps the child stay within a window of tolerance as they explore challenging thoughts, feelings, and sensations. Just as a caregiver regulates an infant, the therapist leads the way—modeling authenticity, congruence, and presence.

Because over 60% of communication is non-verbal, it’s essential that the therapist’s verbal and non-verbal signals align. This alignment builds trust and safety, opening space for integration.

The Tenets of Synergetic Play Therapy

The following nine tenets support SPT therapists in understanding their role and guiding clients toward integration and regulation:

To track therapeutic progress, SPT integrates:

These processes guide treatment planning, goal setting, and integration over time.

Training & Certification Pathway

SPT is taught across multiple platforms, including the Lessons from the Playroom Podcast, blogs, YouTube videos, and formal courses. Certification is available for both licensed mental health professionals and non-clinicians.

Prerequisite: Must be working with children or have prior experience doing so. Those seeking CE credit must be enrolled in or have completed graduate-level mental health training (or equivalent in their country).

Level 1: Introduction to Synergetic Play Therapy

Level 2: Certified Synergetic Play Therapy Program

Level 3: Certified Synergetic Play Therapy Supervisor Program

Strengths of SPT

SPT can serve as either a foundational play therapy framework or be layered into an existing one. Its principles apply beyond children—extending to teens, adults, groups, and families.

SPT centers therapist authenticity, self-regulation, and congruence, supporting both therapist and client transformation. This emphasis reduces compassion fatigue and vicarious trauma while preparing therapists to hold intensity in the playroom, including aggression and dysregulation.

Why Therapists Love SPT

Scope of Practice & Population Considerations

While SPT tenets are broadly applicable, Level 1 focuses on children ages 4–11. Therapist readiness and ethical scope are emphasized, and parental involvement is often a vital component.

For more complex family systems, therapists may require additional training. SPT therapists are encouraged to continue consultation with Certified SPT Supervisors to responsibly integrate the model across diverse populations and challenges.

Who Thrives in This Model

Therapists who are drawn to SPT typically:

SPT is not well suited for those looking for a primarily cognitive modality of play therapy. It calls for presence, creativity, curiosity, and a desire to evolve alongside one’s clients.

Publications & Research

The Synergetic Play Therapy Institute collaborates with the SPT Foundation and academic partners to conduct and publish research. Explore the Publications section for access to peer-reviewed articles, book chapters, and books.

The heart of Synergetic Play Therapy lies in the synergy between therapist and child—a relational field where nervous system regulation, authentic connection, and co-regulation pave the way for transformation. When the therapist becomes the external regulator, children can access and move through challenging internal experiences in ways that are safe and reparative.

This synergy not only supports the healing of the child but also fosters integration for the therapist—bringing both into deeper connection with themselves and others.
