Dallas Senior Interclub....

The Dallas Senior Interclub - DSI - is an interclub golf league consisting of 9 DFW area country clubs.
The DSI organizes competition between all participating clubs with tournaments conducted at each club and a season-finale tournament between the 4 best performing club teams. Participants must be at least 50 years old. DSI events are conducted April through September with events held on Monday or Tuesday morning. The list of participating country clubs and the 2017 schedule for each tournament is shown below. The championship tournament is held in September.

Tournament Format
Each club fields a 10-person team; and the best 8 scores are used in a modified stableford format to determine the winners of each event. Each participant's stableford quota is adjusted (upward or downward based on their performance) after each event in which they played.

All male Thorntree golf members who are at least 50 years old are welcome to play in the DSI.
About 10 days before each DSI event, everyone that expressed an interest in playing in the DSI league is contacted by email and asked if they're interested in playing in the upcoming event. The 10-person Thorntree team is selected from those that respond saying they want to play in that event. All handicap levels are welcome and the modified stableford format (adjusted upward or downward after each DSI event) makes for a very fair format.


  • There is a one-time $30 enrollment fee for each player to join the DSI (payable when you play in your first tournament).
  • Each tournament participant pays a $30 entry fee which funds the prize money for that event. All prize money ($2,700.00 per event) is paid out to the top five teams as shop credit at the host club's pro shop.
  • Each participant is charged a cart fee, typically $20-$25. No greens fees are charged.
  • Lunch is available (optional) after each event for $20-$25.

If you want more information or are interested in playing in DSI events, please email Steve Byron, Thorntree's DSI Coordinator; and he'll add you to list of available players.
