Lauren Ritvo

Tang Soo Do Instructor

Martial arts has been a part of my life since I was just five years old. I earned my first-degree black belt at the age of nine and achieved my second-degree black belt at twelve. Growing up in martial arts taught me the importance of discipline, perseverance, confidence, and respect—values that continue to shape who I am today. Today, I am also a licensed physical therapist, bringing a unique understanding of the human body, movement, strength, and injury prevention to my martial arts background. I am passionate about helping others build confidence, develop physical skills, and reach their full potential both inside and outside the dojo. Riverview Martial Arts is more than just a martial arts school; it’s a family. Having grown up in the martial arts community, I understand the positive impact it can have on individuals and families. My dad founded the school, and my siblings and I continue to be involved in its martial arts and exercise classes. We take pride in creating a welcoming, family-oriented environment where students of all ages can learn, grow, and challenge themselves while building lasting friendships. I am proud to be part of the Riverview Martial Arts family and to help carry forward the values and traditions that have meant so much to me throughout my life.
