Without reservations, I highly recommend Master Seung's Taekwondo - Argentia. My son was enrolled in the in-school program Karate Kids which Master Matthew taught. When Karate Kids finished, we transitioned to Master Seung's Taekwondo - Argentia in 2012.
Masters Ken, Se'era, Ryan and Matthew were his initial instructors and were later joined by Masters Ho and Johl. It's been gratifying to watch my son's confidence grow over the years and can attribute it to his taking Taekwondo in a warm, friendly family-oriented environment. The opportunity to act as a peer instructor to the younger children has been most encouraging to his self-esteem.
