FMI in the Community

2017 marks the 22nd year of our Annual Frontier Mechanical Golf Tournament - raising over $36,000.
The tournament this year was held on Friday, July 14th at the Meadows Golf Course in Littleton. As always, the tournament is both a way for us to say thank you to our customers and to support our local community through charitable organizations such as Mile High United Way, The Make-A-Wish Foundation, and The Food For Thought BakPak Program for Jefferson County. We are proud to say that over the years, with the support of participants and vendor sponsorships, FMI has raised over $706,000.00 to give back to the community and grant children’s wishes! We would like to thank this year’s sponsors for their continuing support.
