Backed by science. Built for ADHD.

Accessible, high-quality support for ADHD is a necessity.

At Shimmer, we are committed to raising the bar for non-clinical support by grounding our work in rigorous research, measurable outcomes, and meaningful change. Our commitment is simple: to lead with evidence, deliver with excellence, and ensure every person with ADHD has the tools they need to thrive.

Our methodology

Where science meets everyday ADHD

We strive to provide evidence-based, culturally sensitive, and effective support for individuals with ADHD. The Shimmer Program combines the best of:

Coaching psychology, which enables engagement with the unacknowledged or underdeveloped capacities of ADHDers to improve wellbeing.
Positive psychology to understand what makes life with ADHD a good life and how to bring it about by using strength-based approaches and character traits.
Neurodevelopment & executive functioning research: for inclusive practices to meet the unique challenges of ADHD within the contextual behavioral science paradigm.
Behavioural Science which allows precision in shining the light on what can move the needle in the direction the person wants to go in, whether it is determined by their psychology, their environment or motivational forces.
Phenomenological and existential perspectives which focus on the uniqueness and value of every person’s life journey, and coach towards courage, self-efficacy and authenticity in life.
Lived ADHD experience: to meet these needs, our program is co-designed by people who live it every day

Measurable results that last

Across hundreds of thousands of data points and thousands of member journeys, we track outcomes through structured quality assurance processes which includes post-session surveys, monthly feedback loops, and longitudinal tracking. This systematic approach gives us a reliable picture of member progress and ensures accountability for sustained autonomous change. The evidence demonstrates not only short-term improvements but also lasting gains in how members move towards their vision of good life and achieve their goals.

The Need for Non-Clinical Support

While medications are often considered first-line treatment for ADHD, alone, they do not always lead to improvement in wellbeing and quality of life. Areas such as self-regulation, organization, planning, and time management often remain challenging even when medication is used.

Research shows that non-clinical and psychosocial supports are an essential part of comprehensive ADHD care. Goal-oriented, skills-based supports, including ADHD coaching, psychoeducation, and peer learning, have been shown to help people sustain motivation and improve quality of life. These approaches go beyond reducing symptoms to improve real-life functioning and wellbeing, while also fostering positive identity development, self-compassion, and resilience.

Without non-clinical psychosocial support, ADHD care is incomplete.

The Shimmer Research Lab

ADHD coaching is a rapidly expanding field, and Shimmer is committed to strengthening its foundation.

We see our unique role as both researchers-practitioners: applying insights from established evidence-based fields while also generating new knowledge through original research. With the collective experience of our coaches and members, we’re able to study what works in practice, what supports well-being, what clients value most, and move toward truly scalable, effective ADHD care.

By sharing these insights, we aim to set benchmarks for best practice, advance the evidence base, and ensure that progress in this field benefits individuals with ADHD as well as the wider professional community.

The Hero’s Journey

The Shimmer research team developed a multi-dimensional working model of individualized ADHD coaching, mapping key functional life areas, executive function domains, and psychological processes addressed through the coaching journey. The purpose of the model is to support more contextual, dynamic, and outcomes-informed coaching practice.


We tested this model through rapid case studies which included both coach and client perspectives. The results showed that ADHD coaching goes far beyond task management. It necessarily includes life-span perspectives and supporting growth in positive self-concept, emotional regulation, motivation, values, behavior patterns, and social relationships.

Interpretive Phenomenological Analysis

Traditional clinical ADHD and executive functioning assessments are designed to compare against a “normal,” "neurotypical" brain. And, unfortunately, these tools aren’t sensitive enough to the myriad ways in which ADHD can impact human identity, cognition, emotion, and behavior.

To address this, we used interpretive phenomenological analysis, a research method that examines how people make sense of their lived experiences. By analyzing the words and stories shared by the ADHD community, we identified recurring themes in how individuals describe their challenges.


From these themes, we developed the Shimmer Mastery framework, a reflective tool designed to help members better understand their ADHD and see how it plays out across three key domains of everyday life.

Management of time: how we relate to the past, present, and future

Getting things done: starting, following through, and completing a project

Pause (Emotional regulation): pausing, generating options, and implementing solutions even when under pressure

Practice-based evidence of ADHD Coaching: Localized Delphi Study

The Shimmer Research Lab brought together a council of our experienced ADHD coaches to share real-world insights from their work with clients. Through dozens of case study submissions, we captured their collective wisdom and identified the practices that make the biggest difference in ADHD coaching.



The study was designed to support coach development and increase the field’s credibility, while allowing practitioners to retain their own philosophies and coaching styles.
This type of study aims at exploring the practice-based evidence on the ground to infuse the already established methods in the field of neurodiversity-focused coaching.

Shimmer triple vantage point: Person, Practitioner & Tech

Shimmer occupies a unique position in the ADHD support ecosystem: we serve both individuals with ADHD and the practitioners who work with them. We also hold expertise in digital tools, data practices and technology which is there to support those with ADHD.


This triple perspective allows us to generate practice-based evidence, identifying not only what members report as effective, but also what practitioners need to deliver high-quality, sustainable care through the use of modern digital tools.


Our capabilities allow us to move beyond isolated case reports to identify patterns that inform person-centered, scalable, evidence-informed models of care fit for the digital age.
