About Me
Josephine Mansergh-Johnson is an integrative psychotherapist and researcher specializing in addictive behaviors, trauma, and its intergenerational effects. Her work is grounded in an understanding that when treatment addresses the whole family system rather than the individual alone, both prevention and recovery outcomes improve dramatically.
While still a graduate student, Josie served as a research assistant, delivered peer-reviewed presentations, and pioneered the first internship across Child & Family Services. Josie led nationwide CEU trainings on understanding addiction through an intergenerational, trauma-informed lens and on shifting trajectories through supporting children and families. This work led to her being named a Subject Matter Expert by the American Counseling Association, where she now sits on its Editorial Board for Practice Briefs, and to receiving the Hazelden Betty Ford Slaymaker Scholar's Award for highest GPA and impact across the foundation and wider field.
Since graduating, Josie has returned as Adjunct Faculty teaching Lifespan Development at the Hazelden Betty Ford Graduate School, drawing on her interest in the intersection of developmental counseling and addiction—including ACEs, toxic stress, and developmentally adapting treatment across the lifespan. She later co-authored a meta-analysis in the Journal of Counseling & Development on culturally adapted PTSD treatment.
This summer, Josie joined Pace University in New York as Adjunct Faculty, teaching Civic Engagement and applying psychological principles to local community work. She is currently pursuing a PhD at Pace, where her doctoral research will focus on resilience-based approaches to improving outcomes for at-risk youth in families affected by substance use, known in recovery communities as ‘COAs’.
Today, Josie sees a select caseload at Soho Psychotherapy and continues to consult for Sundial Advisors, a family office advisory, applying her behavioral and systemic expertise to decision-making across cultures and partnerships.
From East to West…
Josie is married to Clinton, CEO of Sundial Advisors. The couple met in London and married at the historic St Mary's Church, The Boltons. They share their lives with two mischievous Bedlington Terriers, Bilbo and Winnie.
Clinton and Josie have traveled extensively together in pursuit of their purpose, including extended seasons in the Middle East. In 2021, they fulfilled a lifelong dream by moving to California, where Josie became more deeply involved in prevention work at Hazelden Betty Ford. In 2025, they relocated to the East Coast so Josie could pursue doctoral studies while Clinton explored new opportunities in New York.
When they're not working, you can find the four of them exploring upstate, Connecticut and Long Island, enjoying coffee, or running along the breezy Hudson River waterfront.
