Crossing the Line: A Fearless Team of Brothers and the Sport That Changed Their Lives Forever is a story of the bonds of brotherhood, family loyalty, the transformative connection between man and horse, and forging a better future from impossible odds.


Crossing the Line by Kareem Rosser

Kareem tells his life story about becoming a polo champion while growing up in the “Da Bottom,” a West Philadelphia neighborhood plagued by poverty and violence. He delivers an inspirational presentation detailing his love for family, horses, and his ability to persevere.


Mental Health

Kareem is no stranger when it comes to loss. At a young age, he lost several family members and friends to violence and drug addiction. He candidly addresses the stigma associated with mental health while at the same time demonstrating vulnerability.


Mentorship

If it weren’t for the crucial mentorship of Work to Ride founder Lezlie Hiner, his brothers, mother, and countless others, Kareem would not be where he is today. He owes his success to those many mentee experiences and believes that is a key to growth for the youth of our world. He is constantly involved as a mentor to many of the Work to Ride members. One of Kareem’s long-term goals is to positively impact the lives of children of all ages, just as his mentors have done for him.


Education

Kareem has used the quote from Nelson Mandela, “Education is the most powerful weapon which you can use to change the world,” as a guiding light in his life. Kareem’s foundational belief in education is the most critical tool for children and people of all ages to excel.
