April Pettengill, Owner, 5th Degree Black Belt

Master April Pettengill began her martial arts journey in the 1980s with Judo during her college years. After a break from martial arts, she found her way back to the dojo when she enrolled her children in ITF Tae Kwon Do in the early 2000s. This sparked a deep commitment to the art, which continues today.

In 2012, she took ownership of what is now Arrowhead Martial Arts and Fitness, where she continues to train and teach. Outside of Tae Kwon Do, April is a nurse and works as a consultant for individuals facing catastrophic injuries and illnesses. She lives in Georgia with her husband and is the proud mother of two adult sons.
