Sean Cowan has Childhood Nephrotic Syndrome, and that makes his kidneys lose protein and his body swell. But that doesn’t stop this determined Pennington resident and his family, who have raised more than $6,000 for the 9th Annual Central New Jersey Kidney Walk, taking place May 22 at Mercer County Park in West Windsor. The Kidney Walk is the nation’s largest fundraiser to fight kidney disease. Sean has led the “Cowans for a Cure” team, raising the impressive amount in only three months. For more information on the 5K walk, which will include music, a free Zumba workout, food, raffles and more, visit donate.kidney.org/centralnj.
