The Union League Golf and Country Club of San Francisco (now called Green Hills Country Club) was constructed in 1929 (opening in 1930) in Millbrae, California, USA. It was one of the most ambitious golf and country club projects of its era in Northern California. It was conceived in the prosperous time that proceeded the Great Depression by a prominent group of San Francisco businessmen (primarily Union League of San Francisco club members) who would spare no expense during the design-phase of the project. The golf course was designed by Dr. Alister MacKenzie who considered it one of the top three courses on the West Coast. The unforeseen economic downturn of the Great Depression caused the club to become financially insolvent and in 1933 it was reorganized as Millbrae Country Club.
