This summer, I am excited to take part in Bike4Chai, an exhilarating and challenging cycling event benefiting the children and families of Chai Lifeline. Every mile I ride and every dollar I raise will help support critical programs and services for more than 6,000 families impacted by illness, crisis, and loss. These services include counseling and case management, meals delivered to hospitals and homes, transportation to medical appointments, emergency financial assistance, insurance advocacy, i-Shine afterschool programming, Big Brothers/Sisters, crisis and trauma intervention, and Chai Lifeline’s flagship medically-supervised summer programs, Camp Simcha, Camp Simcha Special, and Camp Simcha Without Borders.

The impact of supporting these programs is real. My friend and neighbor, Sol Schulman, shared what Chai Lifeline has done for his daughter, Yael. Sol shared the following: "Thank you all for supporting this incredible organization. My daughter and our family have been blessed with the support of Chai Lifeline...". Please see Yael tell her story here

I’ve committed to raising $5,000 for this important cause and I hope I can count on you to help me reach my goal. All donations are 100% tax-deductible.
