Unleash your talent
Duncan is a Performance coach working with athletes preparing to perform at international and national competitions, focusing on mindset, mental skills and sport science to optimise performance.
World-class athletes can feel pressure to perform.
They can feel nervous before competition.
They can have days where they don't want to train.
They can have 'bad' days or moments, and make mistakes.
They question their worth in team selection.
What makes them world-class, is the skills and techniques that they use in response to these moments.
Athlete's of all competitive levels share similar experiences, from international level through to club level.
At DSF Coaching, we lead athletes of all levels all over the world to power their mindset in competition and in training.
Founder, Duncan Foster combines formal training and 15 years proven impact in Coaching, Sport Psychology and Sport Science.

Duncan Foster
I live for the energy of preparation and competition.
I love the relentless pursuit of excellence.
I love my role as a coach - consistently driving you to be confident and assured in how you will perform.
I am fiercely loyal and intensely invested in your development and for you to achieve more and to succeed.
Outside of coaching, I look for different training and events to challenge myself physically and mentally.
I have a phenomenal close support network whom I adore spending quality time with.
I played football to a decent level in the USA, playing for the #2 ranked team in the country in college soccer.
I've now moved on from football and into a variety of events as I strive to see what my body and mind are made of.
Teri is a Certified Mental Performance Consultant (CMPC) through the Association for Applied Sport Psychology (AASP).
She earned her Doctoral degree in Kinesiology and Sport Studies (specialization in Sport Psychology and Motor Behavior) from the University of Tennessee, her Master’s degree in Exercise Science and Sport Studies (concentration in Sport and Exercise Psychology) from Springfield College, and Bachelor of Science degree in Exercise Science (concentration in Motor Behavior; minor in Psychology) from Pacific University. At Pacific, she competed in 4 years of Division III varsity soccer and 2 years of varsity softball.
She has worked with youth, high school, and collegiate athletes and coaches, as well as adult recreational sport participants.
While her primary role is as an Assistant Professor at Adler University in Chicago, IL, USA, Teri loves working with performers on their mental game. She particularly loves helping performers transfer mental skills and strategies from their performance context into their everyday life, in addition to enhancing their overall enjoyment of their performance.
Teri’s ultimate goal is to help performers’ minds to work for them rather than against them, and also perform more optimally, on a more consistent basis.

Danielle DeLisioCMPC

Danielle is a Certified Mental Performance Consultant (CMPC) through the Association for Applied Sport Psychology (AASP).
She earned her Master’s degree in Sport Psychology and Motor Behavior from the University of Tennessee and Bachelor of Arts degree in Psychology from Siena College while also a goalie for the Siena College NCAA Division I lacrosse team.
She has worked with youth, high school and collegiate athletes, military personnel, high school and college coaches, and a variety of sports teams.
Though her work has varied greatly across a wide variety of programs, she has spent an immense amount of time building strong, trusting relationships with performers. She is a mental performance consultant because she loves having the opportunity to help others achieve their highest level of performance.
From experience as a former athlete, there is no better feeling than when you perform your very best. She provides clients with the skills and strategies that can lead to having that feeling of greatness more consistently.
