David Johnson is a PGA golf instructor at Rooster Run Golf Club in Petaluma, a public course in southern Sonoma County designed by Fred Bliss that plays through the open, rolling terrain of the Petaluma Valley with a links-influenced character — native grasses, minimal tree interference, and an exposed layout that makes wind management a genuine element of every round played on the course. The course is well-regarded in the North Bay region for its conditioning quality and its honest test of golf without manufactured difficulty, and Johnson's instruction at this naturally-styled public venue develops the ground game skills, trajectory management, and wind awareness that links-influenced design demands. His teaching is available to the Petaluma and greater Sonoma County golf community at a facility that offers one of the more distinct and authentic golf experiences in the North Bay.
