On Saturday, March 9, Cambridge Health Alliance (CHA) raised close to $50,000 at its annual Bike4Books spin-a-thon to benefit Project READ, its childhood literary initiative, at Tufts University in Medford. More than 70 people participated and raised funds to purchase new books to distribute to Pediatric patients who come to CHA for wellness visits.
