The Byron Nelson, Dallas’ preeminent PGA tournament, will be here in May, but the new website is already on the tee box thanks to work by Johnson & Sekin. Proceeds from the charity tournament, which teed off in 1968, will be used by the Salesmanship Club of Dallas to support the mental health services and urban education provided by the Momentous Institute. New sponsor AT&T is bringing a younger, more technology-driven vibe to the tournament, which is seen in the revitalized website.
