Kenny is the owner and head instructor of our gym. He is a 1st degree blackbelt Over the last 6 years, when he’s not conditioning for tournaments, he has coached kids and adults in their competitions. He is consistently working with students individually to ensure that they challenge themselves and grow within the sport. Kenny is also a black belt in Judo. He has found that Judo’s stand up game is a perfect cross over to train alongside jiu jitsu.
Kenny is a coach that competes regularly. He believes that competing himself is the best way to lead by example. He competes every chance he gets, whether at local tournaments or internationally with IBJJF. He welcomes everyone to the sport, and if you ever find yourself at a tournament without a coach, don’t be afraid to grab him for support. Kenny is also a certified personal trainer and nutritionist.

Add a short description.Hi, I’m Melissa!
I’m a NASM-certified personal trainer, functional medicine health coach, and pharmacist with a passion for helping women in their 40s feel strong, energized, and balanced.
If you’re feeling frustrated by stubborn weight, fatigue, brain fog, or unpredictable hormones, I’ve got you. I combine functional fitness with personalized lifestyle and nutrition strategies to help you optimize your health from the inside out.
My training approach is centered around functional fitness—building strength, endurance, and mobility in ways that support your real life. Through a blend of strength training (with an emphasis on kettlebell work), strategic cardiovascular conditioning, and intentional recovery, we’ll help your body move better, feel stronger, and stay resilient. Whether it’s lifting groceries, keeping up with your kids, or feeling confident in your own skin, your workouts will be designed to enhance your daily life, not just the time you spend in the gym.
Beyond movement, we’ll focus on nourishing your body with whole foods, improving sleep, managing stress, and reducing toxic exposures. My goal is to help you build a foundation of health that lasts, so you can thrive—not just get by.
Let’s take the guesswork out of your health and create a plan that works for you. Ready to feel your best? Let’s get started!
