The Conwy player is turning professional after holding on until after the Home Internationals - ready to play some Ladies Access European Tour tournaments before heading for qualifying school at the end of the year.
The Welsh and English Open Strokeplay champion this year, Boulden also played in a winning Curtis Cup team, Junior Ryder Cup, Junior Solheim Cup, Vagliano Trophy, Astor Trophy and was a regular in the winner's circle at the top ladies amateur events.
“It was a nice way to finish off at the Home Internationals, it was my last ever amateur event and nice to be going out with a win,” said Boulden.
“I am definitely proud of my amateur career, I love playing for Wales so winning three Home Internationals is really nice to have done. After missing out on a place on the Ladies European Tour in final qualifying last year I decided to give it one more year in the amateur game, but I feel ready to turn professional now and I am preparing to go back to qualifying."
In her final year the 20-year-old also won the Ping Welsh Ladies Order of Merit and finished second on the Ladies Golf Union Order of Merit. Her English Open triumph was the first time a Welsh player had ever won that event, while she has also qualified to play in the Ricoh Ladies British Open three times.
