Tim Dexter / Co-Owner

At twelve years old, Tim began his Parkour and Free Running training. His American Ninja Warrior training journey started a year earlier at age eleven. He began teaching and sharing his love for movement with both children and adults at the young age of 14.

Tim has trained with some of the top professional and well known Parkour and Free Running athletes and American Ninja Warrior athletes from all around the world. He is a National Ninja League National finalist, a USA Parkour certified instructor, the founder of Cumberland Valley Parkour and York College Parkour.

Tim has been competing in various Ninja competitions at different Ninja gyms around the country since the 8th grade, and has competed against many of the top professional American Ninja Warrior athletes from around the world. He competed on Season 10 of the national television series “American Ninja Warrior.”


Tara Brown / Co-Owner

Tara is a graduate of West Virginia University, and also shares an alma matter with Tim Dexter… getting her Cumberland Valley High School diploma “just a few” years earlier. Starting at the age of 12, she worked in and years later co-owned a manufacturing company founded by her grandfather in 1978. She sold the company in 2015 to follow her new-found passion for health and wellness.

Through her Community Coordinator position with Athleta Harrisburg, Tara has been able to explore multiple fitness disciplines and has enjoyed them all. One thing she had not yet tried was parkour/ninja warrior training, so it seems only logical that she has partnered up with Tim to start Dexterity Depot. She is honored and excited to help Tim turn his lifelong dream into a reality in Central PA and beyond.


Aaron Lucas / Coach

Aaron has enjoyed watching American Ninja Warrior since he was a kid. He always found himself climbing on anything he could find, and he has been rock climbing since the age of 5. Aaron has competed in 18 different sports including Pole Vaulting, Diving, Ultimate Frisbee and more!

As a kid, it was Aaron’s goal to compete on American Ninja Warrior. It wasn’t until he found out that the age limit had been lowered to compete on the show, that his dreams became a reality. Once getting involved with Tim Dexter and Dexterity Depot, Aaron began training for Ninja on a regular basis and saw immediate improvement in his skills and strength.

Aaron then began competing in Ninja competitions at various gyms around the country and even competed in the National Ninja League Season 4 World Championships! Aaron also had the amazing opportunity to compete in the city qualifiers at Tacoma Washington on season 11 of American Ninja Warrior!

Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot.
