A fun fact about Chad: He has been racing sailboats across the globe for decades semiprofessionally and has even played pro beach volleyball. Additionally, he says “I love our patients. They are often the same kids I cared for early in life and it’s a very rewarding experience establishing a relationship with them and their families. An asset I bring to this department is “kid” being my second language. I am willing to color with the best of them...princess pics, Barbies and all. Being a kid is fun and I realize that I am not here for me. I serve the little people.”
