About Behaviorist Solutions

Behaviorist Solutions is a boutique consulting firm that applies behavioral science to solve complex organizational challenges. We work with organizations seeking practical, evidence-based strategies to improve performance, safety, leadership, and culture in ways that are measurable and sustainable. Our work bridges research and practice, translating behavioral science into solutions that function in real organizational systems. We work with organizations acorss the United States and itnernationally, supporting clients of various sizes and operating in diverse industries.

Our Mission

Our mission is to translate behavioral science into practical, tailored strategies that help organizations create safer, more effective, and more sustainable workplaces.

Our Approach

We believe behavior is at the core of organizational performance. Rather than relying on generic frameworks or one-size-fits-all interventions, we partner closely with leaders and teams to understand how people actually work within their systems.

Our approach is grounded in behavioral analysis and focused on application. We assess organizational processes, environmental conditions, and behavioral contingencies to identify meaningful leverage points for change. From there, we design and support strategies that align people, systems, and goals, so improvements are not only achieved, but maintained.

Because no two organizations operate in the same way, our engagements are intentionally designed rather than templated. We begin with a discovery call to understand the organization’s goals, resources, and constraints. From there, we work collaboratively to identify meaningful leverage points and guide the organization toward the most effective next step.

Our Values

Our work is guided by principles that remain consistent across industries, settings, and organizational size.

  • Science-driven solutions

    We rely on evidence, data, and measurement to guide decisions and evaluate impact.

  • Human-Centered Design

    Solutions are built with the people doing the work in mind; respecting context, capability, and experience.

  • Integrity and Transparency

    We prioritize clear communication, ethical practice, and realistic recommendations.

  • Focus on Meaurable Outcomes

    Success is defined by observable change, not intentions or activity alone.

Who We Work With

We partner with organizations of varying sizes. From small teams to large, complex systems, across the United States and internationally. Our clients operate in diverse industries and share a common goal: improving performance, safety, leadership, and culture in ways that are evidence-based and sustainable.

Speaking and Thought Leadership

In addition to consulting, Behaviorist Solutions delivers keynotes, workshops, and invited talks for organizations, conferences, and professional audiences.

Our speaking engagements translate behavioral science into clear, actionable tools that leaders and practitioners can apply immediately. Topics often include behavior-based safety, leadership and feedback, culture change, psychological safety, and applying behavioral science in complex systems.

Whether addressing executives, safety professionals, healthcare teams, or behavior analysts, our goal is to make science accessible, relevant, and useful.

Meet the Founder

Andressa Sleiman, PhD., BCBA-D

Behaviorist Solutions was founded by Dr. Andressa Sleiman, a behavior analyst, researcher, educator, and consultant with experience applying behavioral science across organizational, healthcare, and safety settings.

Throughout her work in both academic and applied environments, Dr. Sleiman observed a consistent challenge: organizations wanted change, but often lacked practical, science-based guidance that could be implemented within real-world constraints. Behaviorist Solutions was created to close that gap.

Dr. Sleiman partners with organizations seeking thoughtful, data-driven approaches to leadership, safety, and culture - bringing together scientific rigor and applied expertise to support meaningful, lasting change.
