Widening the Window of Tolerance and Supporting Trauma Recovery

A 7-Module Online Course

At a moment when the impacts of trauma are widespread, there’s an urgent need for mindfulness practitioners who can recognize trauma, respond effectively, and support trauma recovery.

Are you WILLING to develop the skills to do this?

Hi there, my name is David Treleaven.

I’m an educator, researcher, and trauma professional who created Trauma-Sensitive Mindfulness (TSM)—a framework that empowers you to teach mindfulness in a safe, effective, trauma-informed way.

How is this relevant to you?

Trauma is highly prevalent. Research tells us that 90% of us will live through a traumatic event, and some will develop debilitating symptoms in its aftermath.

Mindfulness is also increasingly popular. From online meditation programs to grade-school classrooms, people are practicing mindfulness in a variety of ways.

This means that anywhere people are practicing mindfulness, someone is likely to be struggling with trauma.

This isn’t necessarily a bad thing in meditation, but it’s not a simple thing, either.

While mindfulness can help with trauma recovery, the practice of meditation can create particular challenges for trauma survivors. Absent an understanding of trauma, people can end up over-focusing on intense stimuli that requires more than mindful awareness to heal.

For those of us offering mindfulness to others, this lays a certain responsibility at our feet.

First, we need to learn how to recognize trauma, prevent retraumatization, and keep people safe in practice.

Beyond this first step, we can also discover how to offer people life-changing skills that ultimately support their trauma-recovery.

My commitment? To train you to be effective at both.

Below you’ll learn about the path to mastering TSM, specifically through two courses I developed to train you to become a powerful TSM practitioner.

Thank you for being here, and for your practice and work.




First, Do No Harm

Trauma is a form of stress. Mindfulness has been shown to help reduce stress. Therefore, anyone suffering from trauma would benefit from practicing mindfulness.

Straightforward, right?

Not necessarily. Paying close attention to one’s inner-world in meditation can actually create problems for people who’ve experienced trauma. Despite their best efforts, people can end up stuck, dysregulated, and even retraumatized.

To guard against these pitfalls, you can train to be a Trauma-Sensitive Mindfulness practitioner.

In a short amount of time, you can acquire the skills to recognize trauma, respond to it skillfully, and prevent retraumatization in mindfulness practice.

You can learn the specific reasons people run into difficulty in meditation, and specific tools to help them avoid dysregulation and access the full power of mindfulness practice.

But the commitment to “do no harm” only scratches the surface of what mindfulness can offer trauma survivors.

The full potential of mindfulness practices to support trauma recovery can remain untapped if we don’t develop beyond this initial level of training.

With advanced skills, you can offer trauma survivors practices to help them be safely present with a greater range of experiences—ultimately supporting their path of trauma recovery.


A key concept on the path to becoming trauma-sensitive is the window of tolerance—an optimal zone of arousal in the nervous system we can track to support safe mindfulness practice.

As a TSM practitioner, you can learn to identify when someone is outside of their window of tolerance, and then respond with specific modifications that can help them access an optimal zone of arousal and receive the full benefits of mindfulness practice.

But staying in one’s window isn’t the only answer to trauma recovery.

With time and practice, people can learn to widen their window of tolerance and expand their capacity for presence.

In safe and strategic ways, basic mindfulness can be paired with other interventions that can enhance one’s sense of agency, self-worth, and resilience. While mindfulness practices can’t “cure” trauma, they can play a radically supportive role in promoting self-regulation and trauma healing.

Because of this, we combined two training courses: one that teaches you to prevent retraumatization and the second to help people widen their window of tolerance.

Now you can equip yourself with the Complete Trauma Sensitive Mindfulness Training Program for Practitioners

This comprehensive, two-part training includes the fundamental components of preventing retraumatization AND advanced tools to help you support trauma survivors on their path to recovery in mindfulness practice.

The Complete Trauma-Sensitive Mindfulness Training Program for Practitioners is a two-part, self-paced training program designed to offer you foundational and advanced skills in Trauma-Sensitive Mindfulness.

This comprehensive training includes the theory and practice you’ll need to recognize and respond skillfully to trauma symptoms. Whether you’re a meditation or yoga teacher, religious or classroom teacher, or a mental-health professional who utilizes mindfulness, this course is designed for you.

Here’s a closer look at exactly what’s included in

  • Discover the three steps to widening the window of tolerance
  • Learn the distinction between “being with” and “working with” trauma in TSM
  • Integrate a map of tools you’ll be learning in the advanced course (the TSM “Wheel”)

Mindful Gauges: Empowering Trauma Survivors on their Path to Recovery

In this module, you’ll learn an advanced TSM practice that’s key to safely expanding one’s window of tolerance: mindful gauges. Mindful gauges are a way to help people evaluate their response to different stimuli in the present moment. As you’ll discover, mindful gauges are invaluable for helping trauma survivors feel a sense of choice and agency in their practice and lives. 

In Module One, you’ll also:

  • Receive a refresher on the window of tolerance and how it relates to trauma-sensitive mindfulness;
  • Integrate case studies of students and clients that have successfully used mindful gauges in their practice and work;
  • Learn how to assess and discern what mindfulness practices will best widen the window of tolerance using mindful gauges.

Generating Safety: Offering Embodied Practices that Support Choice and Agency

In Module Two, you’ll take a deep dive into the importance of safety and embodiment in TSM. You’ll learn a series of mindfulness practices you can offer clients and students to help generate safety, including embodied exercises that establish a visceral sense of protection—all to support trauma recovery.

In Module Two, you’ll also:

  • Discover how basic, embodied practices around consent can generate an embodied sense of safety for those you’re working with;
  • Learn how the three subsystems of the Polyvagal Theory apply to TSM—specifically our ability to help people “neurocept” safety in practice;

    • Integrate contemporary research on mindful self-compassion and connect this to TSM practice;
    • Learn about the potential risks and drawbacks of self-compassion for trauma survivors in practice, including working with shame;
    • Integrate three guided, trauma-sensitive self-compassion practices you can offer to students and clients.

    Truth, Reality, and Social Context: Creating Belonging in a Time of Division

    In Module Six, you’ll explore how best to create belonging in the settings you work within—without disappearing dynamics of power and social context. Using a trauma-sensitive lens, we will explore dynamics of “othering” and “belonging” within TSM, and you’ll learn practices that integrate a systemic understanding of trauma to help build safety and trust.

    In Module Six, you’ll also:

    • Hear strategies to help navigate the tension between the “truth” that we are all equal and the “reality” of being treated differently because of our identity;
    • Discover embodied mindfulness practices that support dignity at individual and collective levels while staying with discomfort;
    • Learn about the ways that social context connects to systems theory and the window of tolerance, and how this can support you as a TSM practitioner.

    Cultivating Presence: Healing Ourselves and the World with Mindfulness

    In this final module of the course, we’ll return to the healing power of mindfulness with respect to trauma—specifically through the practice of RAIN (Recognize, Allow, Investigate, Nurture). You’ll learn how RAIN helps cultivate presence, why this is so powerful in trauma recovery, and trauma-sensitive modifications that can be applied to a guided RAIN practice.

    In Module Seven, you’ll also:

    • Learn why trauma survivors have difficulty cultivating presence because of dysregulated arousal;
    • Discover the two specific reasons why presence is so important within trauma recovery (and how you can integrate this into your teaching and practice);
    • Learn to offer RAIN meditations in a way that can support people’s presence and help widen their window of tolerance.

    Towards Completion: The Advanced TSM Finale

    In the Finale, we’ll review the new tools that are available to you within TSM, remind you of how they fit together, and reveal new ways these tools complement one another. You’ll also:

    • Be reminded of the importance of mindful gauges in empowering survivors within TSM—particularly by supporting discernment;
    • Hear stories from people about their own process of discovery and practice within TSM;
    • Be offered a chance for closure in a dynamic, trauma-sensitive way.

    The Complete Trauma-Sensitive Mindfulness Training is proud to offer CE units through our CE partner for a wide variety of professions. The Introductory course offers a total of 6 CEUs and the Advanced course offers 14 CEUs. More information can be found below. 

    Is the Complete Trauma-Sensitive Mindfulness Training all pre-recorded materials?

    Yes. The entire training was recorded while being taught to a live cohort of participants. These programs were dynamic, impactful, and participants reported significantly expanding their understanding of TSM through the course. To ensure more practitioners had access to this comprehensive training (and at the request of many practitioners), we converted the program to a self-paced study format designed for you to complete at your preferred pace.

    Is this course intended for professional training or personal healing?

    This course is offered as a professional training for mindfulness practitioners. While some benefits may result from learning or practices, it is not intended to be an individual trauma healing course.

    I understand this is not a trauma healing course, but I am a mindfulness practitioner who has experienced trauma. Is this course for me?

    If you’re taking the course explicitly to heal your own trauma, this course will likely not be a good fit for you. Given the ubiquity of trauma exposure, however, it’s common that a mindfulness practitioner taking the course will have experienced trauma, and we encourage you to pace yourself and be self-responsive as you move through the material. There’s also a 7-day money back guarantee with the course, so if you take the course and find that it’s not a good fit, you can always ask for a refund.

    How long can I access the sessions online?

    You will have lifetime access to all sessions following the completion of the course.

    Is there a group discount available?

    Yes, for groups of 5 or larger. Please email us at support@davidtreleaven.com to inquire.

    Do you offer scholarships for this program?

    Yes, we have scholarships available for this course. Given that trauma disproportionately impacts marginalized communities, these scholarships will prioritize people of color, poor and working class people, and others who are marginalized by systems of oppression and subsequently have less access to resources. If you would like to apply for a scholarship, please reach out to us at: support@davidtreleaven.com.

    Will Continuing Education Units (CEUs) be offered for this course?

    Yes. CEUs are offered for most professions for both the Introductory and Advanced TSM courses through our Continuing Education (CE) partner. The Introductory course offers a total of 6 CEUs and the Advanced course offers 14 CEUs. CEUs are broken down per module, so you can obtain the full 20 or a lesser amount. At the end of each course module, you will be presented with a link to our CE partner’s page, where you will be asked to pay a small fee ($15/module) and take a short true/false test to obtain the CEs for that module. More information, including the professions that our CEUs are available to, can be found on our CE partner’s page.
