Brian is the builder and creator of Derti Development. His creative mind is never ending with possibilities to test your physical and mental limits. He has used all 10 acres at Derti to build 3 amazing courses that run through the woods, totaling 2.5 miles with limitless obstacles. When he is not making improvements and new obstacles at Derti, he can be found traveling the east coast on the build crew for Bonefrog.

She now uses similar techniques using the obstacles at Derti to help people conquer fears and push through limiting beliefs to become the best version of them selves physically and mentally.
