Expert-Led Training from BCBAs® Who Care About the Future of ABA

The Dojo isn’t just about earning CEUs—it’s about learning from passionate, ethical, and experienced BCBAs® who are committed to sustainable, client-centered ABA. Meet the instructors who bring real-world expertise, mentorship, and practical strategies to every course.

Why Our Instructors Stand Out

Our instructors aren’t just educators—they’re dedicated BCBAs® with real-world experience who have navigated the same challenges you face. They bring practical, ethical, and client-centered approaches to their teaching, ensuring you gain actionable insights that make a difference in your career.

  • Not Just Theory—Real-World ABA Experience

    Our instructors are active BCBAs® who have worked in the field, faced the challenges you’re dealing with, and developed strategies that actually work.

  • Committed to Ethical, Client-Centered Practices

    Every instructor is selected for their dedication to sustainable, ethical ABA that prioritizes both client autonomy and practitioner well-being.

  • Diverse Perspectives & Expertise

    From supervision and ethics to assent and self-care, our instructors bring a wide range of knowledge and lived experience to their teaching.

  • Ongoing Mentorship & Support

    Inside the Dojo, learning doesn’t stop at a CEU course—our instructors are engaged in the community, offering mentorship, Q&A sessions, and real-time support.

A Growing Network of Expert Instructors: We believe that a diverse range of experiences and perspectives strengthens the field of ABA. Master ABA and the Dojo are continually expanding our roster of instructors, seeking BCBAs® who share our commitment to compassionate, client-centered care. This ensures that you benefit from a variety of teaching styles, expertise, and real-world applications of ABA principles.

We are always working with experienced, ethical BCBAs® to bring new insights and expertise into the Dojo.
