The decision to change its status was made in September.
"It was just to primarily focus on the membership and to accommodate their needs and keep the golf course in excellent condition," said Hillary Ames, the director of membership.
The club, which is in the gated Westridge community, will expand the Oaks Grille restaurant and its patio area as well.
Cost of the average membership is $40,000, which is a refundable deposit if the member leaves, according to Ames. They are not equity memberships, meaning members don't own a part of the club.
Since the TPC already was a semi-private club, it had between 300-330 members.
"People are asking us if we're dropping our name, but we're not. We still have networking privileges with the (other) TPC courses," Ames said.
Nobody designed this course. Nobody with a pencil and $2 million and five bulldozers. This was made by nature. It comes out of the ground. It was done with wind and rain and sun and the help of a few sheep. And so, while, for most Americans and other people, it’s not love at first sight at St. Andrews. St. Andrews’ Old Course is like a dry martini, an acquired taste, and, as such, it remains with you forever. JACK WHITAKER
