I've been training at The Underground/Shamrock MMA for about a month, and my experience has been great so far. They even offer a free one-day lesson, which makes it easy to try things out before committing.
The coaches are welcoming, knowledgeable, and really attentive. They break things down in a detailed way and give you that one-on-one feel, even in a group setting, tailoring feedback to what you personally need to improve. No matter your skill level, everyone here is respectful, which makes it a comfortable place to learn and grow.

I cannot recommend Shamrock MMA enough! I’ve been training here for 3 years, starting out as a complete beginner, and the experience has been nothing short of incredible. Coach Janssen is extremely knowledgeable and truly invests in his students' progress. What stands out most to me is how supportive all the coaches are—they create a welcoming, encouraging environment where you feel comfortable learning the ropes but are still pushed to be your best. If you are looking for a top-tier martial arts school to call home, this is the place.
I started training with Coach Jannsen February 2020 via my corporate role.
As COVID hit, we shifted to virtual training which we’ve maintained over the years.
I’ve trained with Coach in person, remotely, and with a broad array of students. You will not find a more technically sound (and genuinely warm) instructor.
Coach Jannsen is the most gifted educator I’ve met. He could instruct on anything he chooses; he happens to operate in MMA and improving the health (and safety) of countless students.
He has vastly improved my health over the 6 years we’ve trained and I look forward to many more.
Thank you, Coach!
