We were honored to donate to The Children's Hospital of Philadelphia. They are at the forefront of providing the highest quality, compassionate, and family-centered care, ensuring that our little ones have the best possible chance at a bright and healthy future. Our golf tournament allowed us to donate $80,000 to this amazing foundation. Thank you to all who participated.  Let's continue to make a difference in our communities!  The video recaps an outstanding day!
