Her practice has ranged from youth performance athletes to elite and professional athletes and coaches that are part of National squads.


Nicole’s primary aim is to help her clients generate a greater sense of self-awareness, where together they can develop their skill set to manage challenges throughout their athletic journey and ultimately support them in their efforts of goal attainment. Nicole is passionate about providing proactive support, whereby clients develop their psychological resilience and skills throughout their athletic careers so that when difficulties or setbacks arise, they are better equipped to handle them.


Nicole is available to deliver support in a 1-2-1 capacity where specific individual needs are developed, integrated sport psychology support into training and competition/performance environments, and group workshops.

My role is to help individuals navigate those challenges."
