The Safe and Sound Protocol (SSP)

Many people arrive carrying patterns that feel stuck — chronic stress, sensory overload, anxiety that seems to appear from nowhere, or difficulty connecting and engaging. These patterns make sense. They're the nervous system doing exactly what it learned to do to survive.

 SSP is offered in-person at our Chicago office and remotely for clients throughout Illinois, with delivery determined by clinical judgment and individual need. 

SSP works at that foundational level — helping the body find enough safety that something new becomes possible.

Dysregulation doesn't look the same for everyone. For some, it shows up as being stuck on — chronic anxiety, hypervigilance, sensory overwhelm, a body that can't seem to downshift. For others, it's stuck off — low energy, disconnection, difficulty engaging or finding motivation.

When the nervous system can't move fluidly between these states, it affects everything: how we feel, how we think, how we relate to others. SSP works at that level — supporting the system's capacity to shift, so regulation and connection become more available.

The Safe and Sound Protocol (SSP) is an evidence-based, sound-based intervention grounded in the neurobiology of safety. Developed by Dr. Stephen Porges, author of Polyvagal Theory, SSP uses specially filtered music to help shift the nervous system from a chronic defensive state toward regulation, connection, and resilience. SSP works through the auditory system to stimulate the vagal nerve complex and activate the social engagement system — supporting the nervous system's capacity for presence, connection, and therapeutic progress. 

Higher-order functions like attention, communication, problem-solving, and learning depend on how well the nervous system processes incoming sensory information. Neurological development builds from the ground up — but when the foundation is disrupted by early experience, life stressors, or neurodevelopmental differences, regulation and connection become harder. SSP works at that foundational level, designed to support the nervous system in shifting toward safety and is intended to complement other therapeutic approaches and modalities.  

SSP is suitable for children and adults and is well-suited for individuals navigating:

• Trauma and complex trauma
• Sensory sensitivities and auditory processing differences
• Anxiety and emotional dysregulation
• Difficulties with social communication and engagement
• Neurodevelopmental differences
• Sleep disruption and executive functioning challenges

Polyvagal Theory focuses on what is happening in the body and nervous system, and how our sense of safety, danger, or life-threat shapes our behavior and capacity for connection. Developed by Dr. Stephen Porges, it provides a scientific framework for understanding why "bottom-up," physiologically-based approaches — like SSP — can create meaningful change in how we feel, think, and relate to others. 

SSP is delivered in phases, beginning with an intake and assessment and moving through structured listening sessions at a pace that fits your nervous system. The full intervention totals five listening hours, typically delivered in 30-minute increments — though actual frequency and duration will vary based on individual responses. It may be necessary to slow down significantly, and that is a normal and expected part of the process.

Each delivery plan is individualized based on clinical features, history, circumstances, and tolerance.  Sessions may be in person at our Chicago office, remote for clients throughout Illinois, or a hybrid — determined by clinical judgment and individual need.  Not all clients are appropriate for remote delivery; some individuals need direct therapist presence for safety and effectiveness.

Prior to beginning, we'll discuss scheduling, environment preparation, activities during listening, co-regulation support, headphone fit, what to avoid, and any individual considerations. For remote delivery, additional planning is required to ensure the home environment is prepared to support a safe and effective experience.

Throughout the process,  your SSP-trained therapist  supports your nervous system, monitors your responses, and adjusts pacing, timing, and frequency to ensure the safest and most effective delivery.

 SSP is available as a standalone service or integrated with ongoing treatment — you don't need to be an existing therapy client to access it. Clinical support throughout and after delivery is essential, not optional. The nervous system needs time to adapt and settle, and benefits can fade without continued follow-up. Most gains emerge 2–6 weeks after completion, as SSP potentiates neuroplasticity and enhances the impact of subsequent therapy. Clients typically see the fullest benefits 6–8 weeks out. 

 Stress lives in the body. SSP is a physiologically grounded approach that helps the nervous system shift out of chronic defense and build capacity for regulation and connection. Research supports what clinicians see in practice:

• 85% of clients with anxiety symptoms reported improvement post-SSP
• 81% of clients with depression symptoms reported improvement post-SSP
• 87% of clients with trauma-related symptoms reported improvement post-SSP
• 84% of clients experiencing challenges with psychosocial functioning reported improvement post-SSP
