Sidney Mandis

Sidney is a compassionate psychologist specialising in both general and performance psychology, integrating evidence-based therapeutic methods with a holistic approach to help individuals and athletes achieve mental wellbeing and peak performance.

With a commitment to personalised care, Sidney works with people across the lifespan to address a broad range of psychological concerns including anxiety, depression, trauma, stress, burnout, ADHD, ASD, body image issues, low self-esteem, addiction, anger management, and relationship difficulties. In the realm of performance psychology, she supports athletes from diverse sports to develop mental skills, manage performance anxiety, build confidence, enhance motivation, and navigate the psychological challenges associated with injuries, mental fatigue, and competition pressure.

Sidney’s passion for performance and psychological resilience is informed not only by her clinical training but also by her personal experience in strength sports. She has been weightlifting since 2013, powerlifting since 2019, and became a personal trainer in 2019 — experiences that deepen her understanding of motivation, discipline, growth, and psychological recovery.

Known for her warm and evidence-based practice style, Sidney emphasises collaboration, resilience, and empowerment, helping clients build mental strength and achieve meaningful, sustainable change in both daily life and performance contexts.
