WE ARE a world leader in the areas of education, research and outreach in the turf industry. Initiated in 1929 through the efforts of committed clientele, it was one of the first turfgrass programs in the nation. It was the first to employ a turfgrass extension specialist (1934), the first to graduate a Ph.D. turfgrass scientist (1950), the first to offer a two-year technical program specifically for golf course superintendents (since 1957), and the first to offer an undergraduate major in turfgrass science (since 1992). But being first is not all that counts; it is the quality of the program that really matters. This app is for current students and alumni to stay informed on upcoming events, Turfgrass news and class schedules. Download now and stay connected with one of the world's most renowned Turfgrass Programs!
