Brittany Fowler
CrossFit Coach
ABOUT BRITTANY FOWLER

Brittany went on to serve in the Army where she was named Company Soldier of the Year (2007) and won JTF-71 Battalion Soldier of the Year through APFT. Brittany got her first taste of CrossFit via Community WODs with the original Contender CrossFit crew. She was immediately hooked and wanted to train and learn as much as possible. It drove her to earn her Level 1 certificate and officially begin coaching. “I truly believe people make their own happiness. If you aren’t happy, change your life. If you don’t know how to change it, I’m always willing to listen and give advice.”

Yasminda Serrano
CrossFit Coach
ABOUT YASMINDA SERRANO
Yasminda always had a love for fitness and body movement ever since she was young. She dabbled in different areas of dance to include High School Dance Team, Folklorico and Middle Eastern Dance where she spent over decade in. Though she always kept moving a little her day job was working in an office and for the most part kept her pretty sedentary working on a computer for over 8 hours a day. She knew a change needed to happen and with the help/guidance of a Coach/ Friend she began working out at Contender CrossFit without realizing the affect this would greatly have not only her fitness but her entire life. Seeing the transformation that occurred in not only her life but many of her friends she knew that she needed to learn more resulting in leaving her job in Corporate America to pursue a career in fitness.
Prior to coming to Contender I rarely touched a weight and if I did it was never over 10 pounds. I then found this group of amazing, strong woman and men whom not only encouraged me but helped me reach depths of my own strength that I never thought possible. Realizing how strong and uplifting women (and men) can be I wanted to be on the other end of that helping those whom couldn’t see their own true potential and wanted to dedicate my life to helping others find themselves through fitness as I did.

Trevor Harvey
CrossFit Coach
ABOUT TREVOR HARVEY
Trevor is a CrossFit Coach and General Manager at Contender CrossFit WhiteCap. He has loved fitness and health since he was a child. He grew up playing Baseball, Dancing, and Speed Skating. As a young man, he obtained his Bachelor of Science degree from the University of Texas at Arlington in Paramedicine. He served as a paramedic for MedStar and CareFlite in North Texas for 10 years. Fast forward two children and six grandchildren later; Trevor and his wife moved to Corpus Christi in 2015 and that is where he found his love for CrossFit.
He joined CrossFit in 2017 after his mother suffered a heart attack. He realized that he didn’t want that to be him, so he joined the local CrossFit gym and in a matter of months, he was in the best shape of his life and competing in local CrossFit competitions. He wanted to share his experience as an older CrossFit athlete with those who thought it was only for the young and fit. Trevor enjoys helping athletes of all ages and fitness levels achieve their personal goals and become the best version of themselves. “I always tell my athletes that it’s just mind over matter; if you don’t mind, it don’t matter. Age is just a number and I love watching my athletes achieve the goals they didn’t think they could ever achieve. Their win is my win.”
