Thorntree Golf Club was built in 1983 by the Richard Mai Family. For five years, we played host to the Byron Nelson qualifying tournament, PGA Tour stage qualifying and sectional qualifying for the Texas State Open. Rated as one of the most challenging courses in the Dallas/Fort Worth area by the Dallas Business Journal, this challenging golf course offers you flawless fairways and beautifully manicured Champions Bermuda greens on which to test and improve your skills time and again.
