With the warm days of spring around the corner, now is the time of year people reflect on ways they can grow their support of the community. BJ’s Wholesale Club is challenging the Bay State to help increase the Boston Children’s Hospital’s (BCH) registered donor base by 5,000 donors through the end of 2016. Anyone in the Commonwealth can join BJ’s and BCH in raising awareness of the significant role blood donation plays in pediatric care by registering as a blood donor.
