Our Story
A Better Place to Train
Cornerstone Jiu-Jitsu was founded by Erik Sommer in 2026 after more than two decades of training, coaching and competing.
The academy was built around a simple idea: people come to Jiu-Jitsu for different reasons, and the training environment should support those differences. Some students want a great workout, stress relief and good people to train with. Others want to compete, sharpen their skills and be pushed to their limits.
Cornerstone is designed to support both, with high-quality instruction, a professional training environment and a culture built around respect and consistent effort.
Our Training Philosophy
Clear Instruction.
More Time Training.
Cornerstone keeps instruction clear and efficient so students can spend more of the class drilling, training and applying what they learned.
Students are expected to treat one another with respect and train hard, but the pace can be matched to the individual. Some students want to be pushed hard. Others prefer a more relaxed and enjoyable pace. The coaching approach meets students where they are and adjusts to their mindset, experience and goals.
“We can only absorb so much information at once. The goal is to give students what they need, then let them train.”
What Matters Here
