Cathi Donahoo works with Titleist Golf Club Operations, connecting her to one of the most respected equipment brands in the game and giving her students access to a level of product knowledge and fitting expertise that most instructors can only approximate through general equipment education. Her position within the Titleist organizational structure means she understands how club specifications — shaft flex, lie angle, loft, grip diameter — interact with individual swing mechanics to produce the ball flights and distances that actually show up on the scorecard, rather than the theoretical performance printed on the club head. For players who want to understand whether their equipment is supporting their swing or working against it, Donahoo's background in golf club operations provides a technically grounded answer.
