Sensei Julie
Hi! My name is Julie Schummer and I am a second degree black belt in American Freestyle Karate and lead instructor here at Landshark Martial Arts for all age groups. I am 21 years old and I have been doing martial arts my whole life. My dad had me punching and kicking before I could walk and I’ve loved it ever since! I obtained my black belt in September of 2019 and that is when I started my teaching journey. Teaching is one of my passions and I am always enthusiastic to be in the studio with our wonderful team of instructors and students!

Sensei Tou
Jiu-jitsu instructor / Blue Belt - representing Team Vaghi Northern Region.
My journey into BJJ started back in 2014 when i moved to Silver Spring, MD where i did not know anyone but wanted to meet new people and stay physically active. I decided I should learn a martial art and recalled one of th emain foundations of mixed martial arts (MMA) is Brazilian Jiu-Jitsu. I googled the nearest BJJ gym and came across Bartman MMA - Gracie Jiu-Jitsu - Self Defence. I attended my first class and caught what many would say the "Jiu-Jitsu Bug" and was instantly all in. I trained under Professor Greg Bartman in Gracie Self-Defense for three years. In 2017 I moved back to Wisconsin to be closer to my family and started training under Professor Bill Krieg. I am excited to bring BJJ to Land Shark Martial Arts focused on self-defense and the development of self-improvement.
