How to become a pga caddy
Offer to work as a golf course caddy for local golfers at your area country club.
Being a hard worker will definitely get your further in the world of golf and you never know what professional golfer may hear your name.
Learn as much as you can about caddying and the sport of golf in general.
No professional golfer will ever hire a caddy who has no experience or does not know anything about the sport. It is important to understand not only every aspect of the game, including rules and scoring, but also how the clubhouse operates.
