Coen Pross is a PGA golf instructor at Presidio Golf Course in San Francisco, one of the most historically significant and scenically positioned public golf facilities in the western United States — a parkland course inside the Presidio National Park with views of the Golden Gate Bridge and San Francisco Bay from several elevated positions, on land that has been used for golf since the late nineteenth century. Teaching at Presidio places Pross in a genuinely unique public golf context: the course operates within a national park, which gives it a sense of place that no amount of landscaping investment can replicate, and the San Francisco golf community treats it as a civic treasure rather than simply a convenient place to play. His instruction serves the full range of that community, from beginners discovering the game for the first time through experienced players who make Presidio their primary practice venue.
