AthleteOS · Expert Partner Trainers
Train With the Right Expert for Your Sport, Position and Development Goals
GESI AthleteOS connects student-athletes with qualified experts matched to their sport, position, age, assessment profile and development goals.
Our trainers are experienced with early high-school athletes — boys and girls entering 9th grade — and with the older age groups GESI will serve as the network expands.

Sport and position
Matching starts with the demands of the athlete's sport and the position they actually play.
Age and stage
Recommendations respect training age and maturation — starting with athletes entering 9th grade.
Assessment profile
Approved assessment results and stated goals shape which development priorities come first.
How Training Happens
In Person, Virtual or Hybrid.
In Person
On-site sessions at schools, clubs and partner facilities where a qualified expert is available locally.
Virtual
Remote sessions for technique review, programming and education when distance or cost is a barrier.
Hybrid
A combination of periodic in-person work with ongoing virtual support between sessions.
Expertise Across Sports
Sport and Position Specific.
The expert network is in development. Expertise is organized by sport and position so athletes are matched to relevant specialists rather than browsing a directory.
Not Just a Trainer Directory
Qualified Expertise. Trusted Standards.
Qualified
Relevant certifications, qualifications and demonstrated expertise.
Vetted
Identity, professional history and appropriate background screening.
Safe
Safeguarding standards and appropriate athlete protections.
Accountable
GESI professional standards, privacy requirements and ongoing review.
GESI expert partner trainers provide additional specialized capacity. They supplement school coaches and athletic programs — they do not replace them, and they take no part in team selection or playing-time decisions.
Access
Expertise Should Not Depend on Zip Code.
GESI is building the network with equitable access in mind — a mix of in-person, virtual and group formats, transparent expectations and pathways that work for families across a range of circumstances, not only those already inside private training ecosystems.
Partnerships
Built With Schools and Communities.
Schools, districts, clubs and community organizations can work with GESI to bring assessments, education and qualified expert capacity to their athletes — coordinated with existing coaching staff rather than around them.
