Chief Clinical Advisor

With over three decades of experience, Carmen Dominguez, LMHC is a psychotherapist, educator, and consultant who has dedicated herself to fostering healing, personal transformation, and societal change. This dedication sets her apart in her field. Drawing from a diverse range of therapeutic disciplines such as contemporary neuroscience, holistic medicine, yoga therapy, and expressive therapy, she brings a wealth of knowledge and expertise to her work. By integrating these disciplines, Carmen creates a therapeutic paradigm centered around honoring individuals’ unique narratives and crafting interventions that catalyze profound healing. She also has a deep appreciation for evidence-based treatment models, constantly striving to broaden our understanding of these modalities to better support those seeking treatment and tap into a greater sense of self. Carmen specializes in trauma, addiction, social justice, and mental health.

In her formative years as a therapist, Carmen was greatly impacted by the HIV/AIDS crisis. This transformative experience influenced her advocacy for safe and dignified therapeutic environments that nurture inner exploration and self-awareness. She has been an adjunct professor at Lesley University for more than two decades, imparting her knowledge and nurturing the next generation of therapists through compelling courses such as “Treating Addiction,” “Culture and Identity,” “Clinical Skills,” and “Children and Adolescent Psychopathology.” As Chief Clinical Advisor, she also trains and mentors the clinical teams at Integrative Life Network’s family of treatment centers.

Motivated by an unwavering passion for expanding the perspective on healing and transformation, Carmen seeks to redefine entrenched paradigms within behavioral health. She envisions a new paradigm based on collaborative synergy among healthcare disciplines to achieve holistic healing and social justice. In her consulting work, Carmen advances trauma-informed DEIB (Diversity, Equity, Inclusion, and Belonging) frameworks within organizations, drawing on her substantive experience.

Carmen’s influence extends globally through co-facilitating transformational experiences with best selling author of ‘Dreaming Down Heaven‘, Gini Gentry, and also the former teaching partner to Don Miguel Ruiz, author of ‘The Four Agreements‘ in Teotihuacan, Mexico.
