Congratulations to Quest martial arts student Lana Powell. We are proud of her accomplishments competing this past weekend in Inverness Scotland. Thank you to all the Tang Soo Do family members who watched out for her since I was unable to attend. All my gratitude and appreciation

Congrats, Lana! She represented Team USA and Quest this past weekend in Inverness, Scotland. Here's a comment from her mom from the weekend-long competition.

"And that’s a wrap! Lana did amazing! Gold in weapons and forms and a silver in sparring! And she competed in grands! Whewww what a trip! Thank you to everyone who has trained her and given her so much support! We are both so very grateful! This kid is all smiles!" - Kim Powell
