Hannah Katherine is a BCBA/LBA with extensive experience supporting individuals with developmental disabilities, their families, and the systems around them. Her background spans home, school, and clinical practice, as well as systems-level improvement work through Harvard University’s Center for Education Policy Research. She specializes in dual diagnoses, communication development, functional assessment, and trauma-informed, neurodiversity-affirming care.

Hannah’s broader professional experience includes leading and supporting systems-level change in public education. At Harvard CEPR, she collaborated with district partners to design and implement continuous-improvement initiatives focused on student support. In that role, she trained school and district leadership teams and provided guidance on organizational change. This work strengthened her ability to train organizations and to understand behavior within broader environmental, relational, and structural contexts.

Across her career, Hannah has partnered with parents, direct support professionals, home health agencies, and multidisciplinary providers. Her approach is practical, relationship-centered, and respectful of each individual’s autonomy. She emphasizes communication, emotional regulation, and supportive environments that reduce distress and allow individuals to participate more fully in daily life.

In addition to her clinical work, Hannah is also a fine artist. Her mixed-media paintings explore emotional landscapes, connection, and the quiet details of everyday noticing. This creative practice informs her interest in how people engage with their environments and how visual elements can support regulation, attention, and well-being. The overlap between behavioral science and creative process shapes many of the experiential tools and engagement strategies she develops through Stellaterra Studio.

Through Stellaterra Studio, she offers:

• Medicaid Therapeutic Consultation rooted in functional assessment, clear planning, and caregiver training

• Private parent coaching informed by Acceptance and Commitment Therapy

• Consultation and training for organizations and clinicians

• Creative, experiential tools that integrate behavioral science with art-based processes

Hannah’s work is collaborative, contextual, and grounded in real-world application. She aims to create supports that families and teams can use with confidence, so individuals feel understood, equipped, and supported.
