Over the past several decades, psychotherapy has produced an impressive library of diagnosis-specific treatments — one for panic disorder, another for social anxiety, another for PTSD, and so on. But most people don't arrive with a single, cleanly defined diagnosis. They arrive with overlapping behaviors, emotions, and thinking patterns that the diagnosis-specific model was never designed to handle. 

Fortunately, a growing body of research points toward a more elegant solution. Across the spectrum of emotional and psychological disorders, a small set of core mechanisms keeps appearing — avoidance and self-defeating behavior, emotional dysregulation, maladaptive thinking and rumination, relational patterns rooted in early experience, a diminished sense of self, and the lasting effects of unprocessed trauma.

Transdiagnostic thinking — the insight that a small set of core mechanisms underlies many emotional disorders — has reshaped how leading clinicians and researchers approach treatment. At Onto, we use transdiagnostic principles to deliver the full complement of available evidence-based treatments, matching each one precisely to the issues driving that particular person's difficulties.

CBT identifies and shifts the thought patterns and behaviors that sustain psychological distress, with one of the broadest and most robust evidence bases in psychotherapy.

DBT builds skills in emotional regulation, distress tolerance, mindfulness, and interpersonal effectiveness — originally developed for severe emotional dysregulation, now applied across a wide range of presentations.

ACT cultivates psychological flexibility and values-guided action, helping people move toward the lives they want rather than simply reducing symptoms.

MBCT integrates mindfulness with cognitive therapy to change a person's relationship to difficult thoughts and feelings. It has one of the strongest evidence bases in the field for depression relapse prevention and extends naturally to anxiety and stress.

Motivational Interviewing is woven throughout our work as a foundational clinical stance — a collaborative, research-supported approach to resolving ambivalence, clarifying what a person most wants, and building the internal momentum for change.

Trauma-Focused Treatments address one of the most common and underrecognized drivers of psychological suffering. Our clinicians are trained in the leading evidence-based approaches:

• Prolonged Exposure (PE) systematically reduces the avoidance and fear responses that keep trauma alive. Research by Onto's Scientific Advisor and colleagues, published in the Journal of Affective Disorders, demonstrated the effectiveness of PE even in complex presentations.

• Cognitive Processing Therapy (CPT) targets the stuck-point beliefs about self, others, and the world that trauma leaves behind.

• EMDR uses bilateral stimulation to facilitate the processing of traumatic memories, with a robust evidence base across diverse trauma populations.

• Written Exposure Therapy (WET) is a brief, highly accessible trauma treatment shown to be non-inferior to Prolonged Exposure in a 2023 randomized trial published in JAMA Psychiatry.

Psychodynamic Approaches attend to the deeper patterns — rooted in early experience and often outside conscious awareness — that shape how a person relates to themselves and others. At Onto, psychodynamic thinking serves as a depth-oriented approach that enriches other treatments by attending to what is happening beneath the surface.

Together, these approaches give Onto clinicians a precise, flexible toolkit — one that can be calibrated to each person's history, goals, and the life they are working to build.
