Who we are
At One and All Education Services, we are committed to supporting students, families, and communities through expert educational advocacy and conflict resolution. We understand that navigating the education system or addressing school-based challenges, such as discipline issues, special education services, or academic concerns, can be overwhelming. That’s why we provide dedicated advocacy to ensure students’ rights are upheld and that families have the tools, information, and support they need to advocate for equitable, student-centered outcomes.
In addition to advocacy, we offer professional mediation and conflict coaching services to help individuals and organizations resolve disagreements in healthy, constructive ways. Whether it's school-based conflict, interpersonal challenges, or organizational tension, our approach is grounded in empathy, collaboration, and effective communication.
At One and All, we believe that every conflict is an opportunity for growth and that strong educational outcomes are possible when students and families are heard, respected, and included. Our goal is to build trust, restore relationships, and foster lasting change through thoughtful, inclusive support—one conversation and one solution at a time.
One and All Education Services was founded by professional mediator, ombud, policy advocate, and educator Bri Sullivan.
Bri began her conflict resolution and advocacy work at the DC State Board of Education, where she mediated conflicts within the DC Public School system, addressing matters related to truancy, bullying, safety, and special education. Driven by a desire to support the greater DC community, she founded her mediation practice to offer tailored conflict resolution services that foster understanding and create positive, lasting solutions. With a focus on building healthier communication and stronger relationships, Bri is dedicated to empowering individuals and organizations to resolve conflicts constructively.
