Andrew Loughrin is a PGA-certified instructor at GolfTEC Pleasanton, part of the national golf instruction network that uses motion-capture technology and high-speed camera systems to give students a precise, data-driven picture of what their swing is doing at every point in the sequence. The Pleasanton studio serves the Tri-Valley's substantial golf population — a region that includes some of the Bay Area's most active golfers — and Loughrin's lesson structure is built around measurable improvement targets rather than vague process goals. Students who work with him over a structured program get before-and-after swing data they can actually evaluate, which tends to produce more consistent follow-through on the practice work between sessions.
