The Professional Tennis Registry reached a major milestone Aug. 31, when the Hilton Head Island-based organization welcomed its 10,000th member in the United States.
"When you provide quality education leading to certification, plus outstanding member services and benefits — membership growth follows,” PTR CEO Dan Santorum said. “Reaching 10,000 members in the U.S., one-third of whom are coaches of color, is a tremendous source of pride for PTR.”
