Approach Description: Welcome to a transformative journey where our connection forms the bedrock of healing. My approach to psychotherapy is rooted in creating a sacred relationship with my clients, delving deep into the roots of the issues at hand. Within this secure and supportive environment, individuals can experiment and develop new skills while rediscovering the empowering potential of existing ones. My passion lies in making personal healing and growth a dynamic, enjoyable, safe, and effective process firmly grounded in evidence-based and client-centred approaches. I deliver personalized care, fostering a collaborative relationship with each individual I serve. While I am equipped to provide education or counselling when needed, my genuine pride lies in guiding clients to discover themselves. I offer an array of tools to deepen well-being and achieve health and personal goals. Every facet of my work is trauma-informed and somatic-based, focusing on healing through the body and reconnecting with your full energy through mindfulness and meditation techniques. I employ an eclectic approach, drawing from gestalt, psychodrama, art therapy, somatic center therapy, trauma-informed therapy, CBT, DBT, internal family systems, inner child healing, and brief psychodynamic therapy. These strategies, honed through extensive training, are deployed as needed to tailor the therapeutic experience to each client's unique journey. As an Argentinean lawyer trained in mediation, I bring conflict resolution techniques into the therapeutic realm. Whether working with couples, families, or corporate clients, I assist in navigating disagreements constructively, fostering mutual understanding and deepening the fabric of their relationships. Welcome to a space where healing is personalized, transformative, and tailored to your unique needs.

Gui Mansilla Practice Description
Welcome to a journey of transformation and empowerment! As a passionate Registered Psychotherapist, coach, and proud member of the College of Registered Psychotherapists of Ontario, I'm here to shatter stereotypes and ignite the spark of positive change in your life. I vividly recall encountering misconceptions about therapy—claims that it's only for those deemed "crazy" and suspicions that financial interests solely drive therapists. These myths were barriers I had to overcome on my path to healing, a journey that began over three decades ago. The guidance of a dedicated therapist helped me navigate toward a life I can now proudly call my own. From a young age, I sensed something was amiss in my world. A tumultuous family breakdown when I was eight thrust us into hardship. Motivated by the desire to spare others from such suffering, I pursued law, earning a Master's degree in Criminal Law and becoming a criminal lawyer in Buenos Aires, Argentina. Yet, disillusioned by the limitations of my legal practice in alleviating suffering, I returned to my heart's calling. Recognizing that true change starts within, I delved into self-discovery, realizing the power of interconnectedness and the ability to shape my reality. My quest for personal growth led me to work with remarkable therapists, mentors, and artists worldwide. Through extensive training and individual therapy, I emerged as a Registered Psychotherapist. It is my profound honour to support others on their healing and awakening journey. Join me in embracing the transformative power of self-discovery, interconnectedness, and healing. Together, let's embark on a thrilling adventure towards fulfillment and empowerment. Your journey begins now! Book a free consultation here
