Semper Fi Athletics
Private
Semper Fi Athletics is an indoor baseball and softball training facility at 10845 Co Rd 74 in Severance, founded by a Marine veteran with more than 30 years coaching youth baseball, football and soccer. It provides indoor skill training for athletes ages 8-18 aimed at improving skills and reaching higher levels of competition, and it also fields competitive baseball teams that play in Colorado tournaments in age groups including 16U and 18U. Athletes book training sessions rather than enrolling in a summer camp.

★★★★★Pedro Vargas PeñaThe Semper Fi Program is such an amazing program and I recommend it for families looking to put their kids in a baseball program! Semper Fi helped me become a better ballplayer and athlete. Coaches here are fantastic!
★★★★★Brittannie LechmanMy son really flourished this fall with the SFA crew. He absolutely loves going to practices and looks forward to any time with the team and coaches. He has smiled more on the field this fall than he has his entire baseball career. I truly believe that the love for the game starts with the kid, but is encouraged and supported with great coaches! It is evident that he feels comfortable failing with the coaches, knowing they will help him build his confidence rather than scold and break him down. Kudos to you all; you’re building something amazing with SFA!
