Health and Well-being Quatuor
Mental health is crucial to the overall well-being of every individual. At Quatuor, our multidisciplinary team is dedicated to providing high-quality care that supports our patients on their journey to optimal well-being.
Multidisciplinary Team
Composed of three psychologists, two psychiatrists, and a neuropsychologist, our team combines its expertise to offer precise diagnoses and treatments tailored to each patient.

Our mental health and well-being department is divided into four complementary areas
Psychiatric Care
The evaluation and administration of psychiatric care at Quatuor are overseen by Dr. Nicolas Garel, supported by his pillar, Dr. Longpré Poirier. Our psychiatrists specialize and focus on acute and refractory depression disorders. Their mission is to optimize the daily lives of patients who suffer, not only with traditional methods but also with innovative treatments over the medium and long term.
Dr. Garel specializes in the use of psychoactive substances in combination with psychotherapeutic approaches for mental illnesses considered resistant to conventional treatments. He participates in many research projects on the use of psychotropic substances, such as ketamine and psilocybin, in patients suffering from depression. He was, in fact, the first to administer psilocybin treatment in Quebec.
Dr. Longpré Poirier studies the correlation between physical health and mental health. His expertise is based on metabolic psychiatry, a recent field in psychiatry that highlights the connection between metabolic health and mental health. He is committed to exploring how physical activity and the optimization of metabolic health can be integrated into a therapeutic framework for mental illnesses such as depression, anxiety, bipolar disorder, and nearly all other brain disorders.
Neuropsychological Care
Under the expertise of Dr. Sonia Marcone, specializing in behavioral disorders, paradoxical sleep, and neurodegenerative diseases, her specialization allows for an in-depth understanding of the links between the brain and behavior. She conducts cognitive and behavioral assessments to help diagnose various conditions, including neurodevelopmental disorders, traumatic brain injuries, age-related cognitive deficits, and neurodegenerative diseases such as Alzheimer’s, Parkinson’s disease, Friedreich’s ataxia, and others.
Psychotherapeutic Care
Our team of psychologists offers a range of therapies tailored to the needs of each patient, including counseling, diagnostic evaluation services, psychotherapy, and coaching: family, couple, and professional. Psychological assessments and treatments are directed by Dr. Elie Rizkallah, psychologist and collaborator in the department’s development. Elie adopts an integrative approach that places acceptance, commitment, and transparency at the heart of his practice. This approach effectively addresses a wide range of disorders, from anxiety and mood disorders to addictive behaviors and crisis situations.
Dr. Katy Davar, on the other hand, has clinical experience in university, hospital/psychiatric settings, and private practice. Katy practices medium and long-term individual psychotherapy. She works with people who have difficulties with depression, stress, or adaptation, as well as those experiencing relationship challenges at the professional or romantic level (conflicts, intimacy, emotion management, impulsivity). She helps individuals clarify their needs and express their feelings to gain a better understanding of themselves, regain confidence in their abilities, and rediscover their strengths.
Psychoeducation
While the other areas focus on supporting patients on their individual journeys, psychoeducation aims to reach a broader audience by making mental health knowledge accessible to a collective public. We offer educational programs designed for employees and business leaders. This helps spread practical resources and mental well-being management strategies within the same community circle. This approach strengthens collective resilience and fosters ongoing support. The goal is to enable leaders to better support their teams and provide them with the necessary resources to prevent or at least reduce burnout, anxiety, and depression. Our teams are committed to identifying various disorders in professional settings and offering recommendations to redesign at-risk situations.
Psychiatry, neuropsychology, psychotherapy, and psychoeducation are intrinsically linked disciplines that advance precise diagnostics. The work of several experts, combined under one roof, yields effective results for our patients and future patients, in the short, medium, and long term. This synergy is essential for the deployment of appropriate, precise, and vital treatments for each individual.
