our Team

A startup organization with deep roots, the professional team at imadi draws on years of experience to provide a comprehensive support system to families facing complex pediatric health diagnoses.

Tzvi Haber, MBA

Executive Director, Founder

A recognized name in the nonprofit landscape, Tzvi’s reputation for visionary leadership and creativity is matched only by his dedication and empathy for the children and families in his charge. Tzvi served as the Assistant Head Counselor at Camp Simcha, a pediatric oncological summer camp, until departing to spearhead the opening of the Mid-Atlantic regional office of Chai Lifeline in 2016. He would go on to be the regional director of the chapter for nearly five years. 

As the driving force behind imadi, Tzvi channels his understanding of emerging communal needs by fostering a movement of systemic change on behalf of his clientele. While still in high school, Tzvi founded the largest youth football league in the state of Maryland. An admired teacher at Beth Tfiloh Dahan Community School, his sensitivity and impact on students earned him the moniker of “Reb Tzvi”, fostering a relationship with hundreds of students which he maintains until today. In the summer of 2020, during the height of the pandemic, Tzvi organized and operated the only pediatric overnight program for children with cancer in the United States. 

Tzvi received his Master’s in Business Administration from University of Baltimore with a specialization in management and leadership.
