Our Story "The Why"


Nothing grips the heart more than a parent afraid of losing their children, especially from something that's entirely avoidable. When our teenage sons lost close friends to drug overdoses, we struggled with how to support and protect them. Our 6 decade combined experiences in healthcare and specialized therapies has helped us recognize that no illness is more misunderstood and poorly treated than addictions. Early identification is key to prevention and recovery. Yet, there's a gaping hole in how people are being assessed and treated compared to other chronic illnesses. Compris is a culmination of our life's work and shared vision to reach as many people as possible with our online tool. We believe Compris can change the conversation from stigma to inclusion—turning substance misuse behaviors into opportunities to save lives. We hope it helps many people.

Meet The Founders


Calvin McGinn PhD, LMFT, RN

Founder / Principal Researcher

A singular goal has informed my personal and professional choices: to be and do whatever helps me and others become better expressions of ourselves. This guiding light has infused my four decades as a healing collaborator in a variety of classroom, hospital, and private practice settings. Whether teaching high schoolers in Jamaica, community college adult learners on a naval base in Washington State, or special education teachers among Montessori and Chicago Public Schools, classrooms and I have always shared a rich narrative of creative, mutual learning.


As a pediatric ICU nurse on a cancer unit in a university teaching hospital, I would often sit with families in the midst of unimaginable pain and despair, offering them a safe container to express the full range of their experiences. This early and enduring exposure to life at the crossroads of medicine and the human struggle forever changed the direction and priorities of my life.


Throughout graduate school, I continued a synergistic dance with family therapy training and ER nursing. Upon graduation, I was invited to teach family practice residents how to bring a therapeutic presence to each patient encounter. Family Medicine was my first professional home. It was also where my ongoing family therapy practice had its roots. Over the next ten years, as Chair of the National Forum for the Behavioral Sciences in Family Medicine, I encouraged my colleagues to bring their therapeutic teaching tools to a national stage, while continuing to nourish healing human collaboration between physicians and their patient families.


As a relationship therapist, I've provided decades of therapeutic guidance and healing among couples, families and teens. Those struggling with brain illnesses, including addictions, have been among my most challenging and rewarding experiences.


When the opioid crisis exploded, I contributed as an addiction counselor and program director for a medication-assisted SUD treatment program in Chicago’s northern suburbs. Once again, I found myself at the crossroads of medicine and the courageous human struggle. In the spring of 2016, I joined the Lake County Opioid Initiative to help develop practical solutions to the growing epidemic.


Reviewing the literature, I was surprised to learn that only two kinds of SUD illness assessment tools were currently available: brief screens for acute illness detection, and 60-90 minute, provider-intensive interviews for risk and level of care placement. For those working in busy ERs or primary care settings, this translated into either insufficient information or insufficient time to adequately assess risk in order to commence targeted care at a critical point of life-threatening illness expression. With this in mind, I decided it was time to bring better answers to this latest human tragedy.


Compris' quality improvement organization is dedicated to providing those answers.

Addictions remove the capacity to make healthy choices. To the extent that the opioid crisis is connected to poor management of chronic pain and related illnesses, including PTSD, my integrated healing methods have found increasing relevance. At each step of my career, the role of neuroplasticity in restoring balance has become more fundamental to the process of sustained, healthy, whole person change. I believe that in order to achieve balance in living, there must be an equilibrium between our habits, reflexes and choices.


I have worked as an Occupational Therapist in a range of therapeutic settings: industrial, psychiatric hospitals, schools, early intervention, assisted living and home health. Early on, I became aware that fully sustainable health required a more integrated biopsychosocial approach. This left me unwilling to simply return clients to their baseline functioning.

In response to my commitment to offering a more complete integration within my private practice, I pursued additional training in the Feldenkrais Method®, which allowed me to more fully explore efficient movement and healthy habits with my clients, Masgutova Neurosensorimotor Reflex Integration (MNRI)®, for re-establishing and re-integrating primary reflexes, and Nondual Kabbalistic Healing (NKH). Through these integrative approaches, I experience improved, mutually nourishing, connections with my clients. 


Through hands-on interventions that reference all four of my specialized trainings, I have achieved considerable success supporting movement efficiency with children and adults whose struggles include developmental delays as well as neurologic, orthopedic, chronic pain, balance, emotional and behavioral challenges.


When Calvin got involved in the addiction field, my backdrop dovetailed well with the new chronic Illness SUD assessment tool he was developing. As Compris' chief operating officer (COO), I collaborate with Calvin to increase awareness of a more useful way of both perceiving and assessing those struggling with addiction. I am assisting with research efforts to confirm the validity and utility of this longer life-saving view of recovery.


Based in Illinois, I continue to provide my clients a wide and well integrated path for sustained health. For more information, you can visit my website at

The Technology

Based on decades of research, we pulled the best and most effective tools together to create the most accurate prediction, prevention guidance, and measurable outcomes.

Compris (French, Com·pree, “understood”) is the only substance addiction assessment available today that offers comprehensive addiction diagnostics and risk stratification consistent with a chronic illness treatment paradigm. Its 13,000 machine learning algorithms translate evidence-based lifetime risk and resilience factors, DSM-5 and HSI illness diagnostics, motivation, denial, and self-reported readiness, into the first complete prevention, treatment, and long-term addiction management guide.
