David Robe is a PGA golf instructor at GolfTEC Rancho Bernardo, part of the national instruction network that uses motion-capture measurement and high-speed camera systems to build a data-precise picture of each student's swing and deliver improvement programs based on specific, quantified targets rather than subjective observation. The Rancho Bernardo studio serves the large and golf-active communities of Rancho Bernardo, Poway, and 4S Ranch — some of San Diego County's most golf-enthusiastic ZIP codes — with instruction built around the kind of before-and-after swing data that gives students a concrete way to track their development and evaluate whether their practice work between sessions is producing the intended mechanical changes.
