To become a Titleist certified club fitter, you need to work for a Titleist fitting account.  Ask your head pro  and he/she should be able to give you direction.

Good Day Cathi.  When you say 'Titleist Fitting account, the golf club/store/ facility... that does mean that the golf faciliy carries Titleist products?  What does one have to do next to get certified?  Thanks

Hi Carlo,  A Titleist fitting account has a Titleist fitting system - a surefit bag, cart, Advanced matrix, so not only do they carry Titleist clubs, they also have a fitting matrix of fitting clubs.  If you work for such an account, please talk with your head pro for more details.

Here is a link to fitting accounts in your area:  http://www.titleist.com/find-a-golf-shop/#fitters  Just put in your area and click on SureFit Bag, SureFit Cart.  Erik Horve at Tustin Ranch, Jim Pooler at Roger Dunn, Sanata Ana, are the two Advanced Fitters in your area.
