I have not heard of any events but I believe Loggerhead golf does titleist fittings

Rumor has it there will be another special Pinehurst event including a fitting. Usually in April. That may appear under Events. Keep checking Fittings for Titleist events in your area. Next level is Premier fitting centers. While Titleist operates this site, all of us end users have no details to directly answer your question. Last I checked Pinehurst is a Premier center, but the fitting fee is set by and negotiated with the course.

There is an event at Sea Island, GA which is about a 6 hr drive from Wilmington. There is also a Titleist Fitting Center at Northstone CC in Huntersville, NC which is about 3.5 hrs away from Wilmington if you take 74 to Charlotte.
