About me
I am a Psychologist and P.E teacher with experience working in both educational and sports settings in Argentina and the United States. Throughout my career, I have worked as a coach, P.E teacher, team psychologist, and grade-level coordinator, supporting athletes, students, teams, and individuals in their personal and professional development. I have training in neuroscience applied to sport, futsal training, positive psychology, integrative psychology, amongst other areas.
I am bilingual in English, born in the US, and have worked in educational and sports institutions in both Argentina and the United States. My experience includes coaching youth soccer programs in NYC and Rosario (Argentina), managing youth futsal divisions, and working at United Nations International School as a Physical Education and Health teacher, social-emotional learning educator, and soccer coach. My experience at United Nations International School allowed me to work within an international and multicultural environment, where I deepened my understanding of human development, communication, and emotional well-being.
Since 2025, I have been part of the Argentine Litoral Hockey Association (AHL, Asociación de Hockey del Litorl), working with both women’s and men’s teams as a team psychologist. I also support athletes and professionals from the sports industry across a variety of disciplines, including futsal, boxing, rowing, tennis, running, and e-sports. My work includes counseling and emotional support aimed at strengthening mental skills, well-being, and performance. I addition to this, I work part-time as an athlete mental-trainer helping individuals strengthen their decision-making, attention, visual skills, focus, motor coordination, reaction time, and executive functioning abilities.

Approach
My work integrates the approaches of sport and performance psychology, neuroscience, positive psychology, counseling, and Nonviolent Communication. Consultations are designed to support you in strengthening emotional connection, values-based decision-making, and authentic relationships, based on your individual needs and interests. I also work with people to navigate pressure and conflict more effectively while cultivating a deeper sense of purpose and greater alignment between their values, performance, and everyday life.
I approach performance and personal growth from a holistic perspective, grounded in my background in Physical Education and psychology, understanding that sustainable achievement emerges from greater self-awareness, emotional awareness, and connection with one’s own values and needs, as well as those of the significant people around us.
Sessions with me are collaborative and tailored to your individual needs. Some sessions are more reflective, while others are more practical and action-oriented, depending on what you need at each stage of the process. I combine sports psychology tools and exercises — including breathing techniques, relaxation, visualization, psychoeducation, and communication skills — with a positive psychology approach to support both well-being and performance.
