Meet Schofield Barracks's Master Resilience Trainer Performance Enhancement Specialist Stephanie Karen Costello, M.A., CC-AASP. Bio in post...

Check out MRT-PE's Karen Costello and Brendan Hanley teaching our newest course applied in the field; "APFT CLINIC: APPLYING MENTAL SKILLS FOR OPTIMAL PHYSICAL PERFORMANCE" The CSF2 Performance Curriculum was developed to integrate mental skills with physical training for optimal performance on the APFT. The training breaks down optimal running form using mental cues. The course typically runs two weeks.

"Karen helps top athletes, mostly track and field and distance runners find their "strength" and form a more positive outlook about themselves and their training," writes Hal Lifson in this May 19, 2012 Patch interview with Karen Costello. "Lifson: Do you represent any athletes that people know? Metta World Peace or Usain Bolt maybe? Costello: (Laughing) I doubt Usain Bolt has much in the way of an inner voice of doubt! But seriously, I'm not really allowed to disclose my athletes per confidentiality. However, I can say that I'm working with three Olympic hopefuls from UCLA, several UCLA collegiate athletes, a USA National Team Water Polo player in Europe (via Skype) and several local high school athletes in various sports."

"I am doing what I love," writes Olympic athlete Liz Costello (no relation to Karen Costello) in her June 30, 2016 Runners World Magazine article about getting back to the Olympic Trials and giving a shout out to those who helped her get there. "...it certainly takes a team—and their support means an incredible amount to me... [including] sports psychology consultant, Karen Costello. Her guidance over the past six months has been an important aspect of my growth as an athlete."

"I used to think working with a sports psychologist was a sign of weakness. How naïve I was," writes Olympic athlete Liz Costello (no relation to Karen Costello) in her April 23, 2016 Runners World Magazine article about working with Coach Karen. "..She helps me to understand how my thoughts affect my emotions...During an Olympic year especially, when there is more pressure to perform well and everyone is seeking every possible edge to make the U.S. team for Rio, I am very thankful for Karen’s generosity in providing this new dimension to my training.
