Hello,
I'm Dr. Lisa!

Dr. Lisa Greene Henderson, PsyD
CEO | Head Psychologist

Dr. Lisa Greene Henderson, Psy.D., is a licensed clinical psychologist whose work is grounded in clinical excellence, thoughtful leadership, and a deep commitment to the individuals, families, and communities she serves. Licensed in Washington D.C., Maryland, Virginia, and Bermuda. Dr. Greene Henderson brings over two decades of experience providing psychological care across diverse clinical, educational, and community settings.

Her approach to psychology is both highly clinical and deeply human. She believes that quality mental health care begins with understanding the whole person—their experiences, relationships, strengths, challenges, and environment. Whether providing therapy, psychological assessment, crisis intervention, or consultation, Dr. Greene Henderson works to create a space where clients feel heard, respected, and empowered to better understand themselves and take meaningful steps forward.

A Commitment to Children and Families

A significant part of Dr. Greene Henderson's work has focused on children, adolescents, young adults, and the families who support them. She recognizes that early experiences can have a profound impact on emotional development, relationships, confidence, and long-term well-being. Her clinical approach emphasizes evidence-based and family-centered care, including interventions such as Parent-Child Interaction Therapy (PCIT). Rather than viewing a child in isolation, she considers the relationships, family dynamics, developmental needs, and environmental factors that shape a young person's experience. Dr. Greene Henderson is especially passionate about helping young people develop a healthy understanding of mental health from an early age. Her goal is not only to address immediate concerns, but also to help children and adolescents become informed, resilient adults who understand their emotional needs and know how to seek appropriate support.

Psychological Assessment With Purpose

Dr. Greene Henderson views psychological testing and assessment as more than a process of identifying a diagnosis. When conducted thoughtfully, assessment can provide meaningful clarity about how an individual thinks, learns, experiences emotions, relates to others, and responds to the world around them. Her approach emphasizes careful evaluation, clinical interpretation, and practical recommendations. The goal is to help individuals and families leave the assessment process with a clearer understanding of their needs, their strengths, and the next steps that can support meaningful progress.

Leadership, Ethics, and Public Service

Beyond direct clinical care, Dr. Greene Henderson has developed extensive experience at the intersection of psychology, public systems, policy, and professional accountability. Her work within complex healthcare and governmental systems has strengthened her understanding of how clinical care, regulation, ethical standards, and public responsibility intersect. She brings particular attention to the importance of protecting the public, maintaining high professional standards, and ensuring that psychological services remain both effective and ethical. Her leadership style is thoughtful and measured. She approaches complex issues collaboratively and with a strong sense of responsibility to the people and communities affected by clinical and policy decisions. This combination of clinical expertise and systems-level perspective has also led to recognition of her ability to contribute to the broader advancement and oversight of psychological practice in Maryland.

Advocacy and Community Service

Dr. Greene Henderson's commitment to mental health extends well beyond the clinical setting. Through her service as a Board Member of The Arc, she has supported work benefiting individuals with intellectual and developmental disabilities, mental health needs, and their families. This service reflects a central value that runs throughout her career: every individual deserves dignity, access to quality care, and the opportunity to be supported as a whole person. She is particularly committed to inclusive systems of care that recognize the diverse needs of individuals and families and ensure that those needs are not overlooked because of disability, diagnosis, circumstance, or background.

Educating the Next Generation

Education and mentorship have also played an important role in Dr. Greene Henderson's professional life. Her experience as an Assistant Professor of Clinical Psychology and as a lecturer has allowed her to teach, mentor, and prepare students at both the college and graduate levels. For Dr. Greene Henderson, educating future mental health professionals is an extension of clinical care. Strong mental health systems depend on professionals who are not only knowledgeable, but also ethical, compassionate, culturally responsive, and accountable to the people they serve. Through teaching and mentorship, she has worked to model those standards while helping future clinicians develop both clinical competence and a strong sense of professional responsibility.

A Philosophy Centered on the Whole Person

At the heart of Dr. Greene Henderson's work is a belief that effective psychological care should provide more than answers. It should provide understanding. She recognizes that seeking therapy or psychological testing can feel deeply personal, and sometimes uncertain. Her role is to bring clinical expertise to that process while ensuring that clients never feel reduced to a diagnosis, test result, or set of symptoms. Instead, her work focuses on helping people better understand their experiences, identify their strengths, recognize patterns that may be affecting their lives, and develop a clearer path forward. Through evidence-based treatment, comprehensive assessment, and compassionate guidance, Dr. Greene Henderson strives to help each client feel more informed, more capable, and more confident in what comes next.
