What makes us unique?

At Breakthrough Therapies, we are committed to easing our patients’ suffering and fostering trust and unity in our community. We believe that patients know their own well-being best, and our therapists help them tap into their inner wisdom, sometimes with the aid of mind-expanding compounds. This innovative approach redefines mental health treatment and builds strong, trust-based therapeutic relationships.

Our team’s passion, commitment and expertise are key to our specific approach to transformational change. With specialized training and extensive experience, we are a friendly, approachable team dedicated to not only making a meaningful difference in our patients’ lives, but also with the medical and psychological communities to inform and bring this groundbreaking science forward.

Our Vision

We believe Nature is integral to healing. By simply being in her presence, without a goal, we can rest, stay curious, and let the trees’ energies heal us. Imagine leaving a doctor’s office and stepping into the serene scent of pine and cedar, under a blue sky, with birds and the sound of water. Our vision is to create these peaceful, beautiful, and safe environments in the heart of the city, easily accessible to everyone.

We strive to be pioneers in Psychedelic-Assisted Psychotherapy, fostering a united and innovative psychedelic community. Our dedication to excellence drives us to develop and apply transformative therapeutic practices that promote profound healing and self-transformation.


Our Mission

Our mission is to alleviate suffering, one person at a time, by providing our groundbreaking method to patients, educating the general public as well as health care providers, and politicians and policymakers. We believe change needs to be systemic, from the top down and the bottom up.

We strive to fuse ancient wisdom with cutting-edge insights to enhance healing. We bring our innovations to life through teaching, training, and mentorship programs for emerging therapists. Additionally, we aim to lead in education and research by collaborating with top minds to dismantle outdated structures and meet the evolving needs of our community.

Our Values


Our Patient is the Core of our Work

We are aware that our patients suffer a great deal, and our work is to alleviate some, or all, of that suffering.  We strive to improve our capacities for deep listening, non-interference, and expanded awareness to provide the best, most transformative experience possible for our patients.



We respect and remain in awe of the infinite complexity of the human mind.  We remain on a constant quest to understand more and commit to applying our knowledge in a nuanced and humble way to achieve the best possible outcomes for our patients.



We intend to remain radically honest and transparent in our dealings with anyone associated with our practice.  We believe full disclosure is at the heart of trusting and sustained relationships with our patients and our partners.




We intentionally strive to always maintain a non-judgmental attitude in all our interactions to create an environment in which all individuals feel understood and included.



We respect and honour the view that there are many paths that lead us to knowing ourselves better, from indigenous and shamanic, to empirical and evidence-based, to spiritual and Gaia-based cosmologies. All are welcome.
