My daughters were students under Shannon at Fort Stewart. Shannon always has patience with the kids. When he needs to be firm with an unruly student he's always respectful and calm.
I've trained at many high level schools and I'd have to say Garth is a World Class instructor.
My son and I are students of BJJ and just PCS here to GA. Coastal Combatives welcomed us into their family. Great Professor and great coaches and great environment . We absolutely love it.
