Who We Are
We’re a collection of trainers and instructors whose passion for fitness is rooted in something deeper: a genuine passion for people.
At Haven Fitness, we’re here to help you get stronger—physically and mentally. We’re not a big-box gym. We’re a curated training experience built to support your progress and help you reach goals you may not even know you’re capable of yet.
Every workout at Haven is designed with three intentions in mind:
Be intentional with your body and your movement. We are here to teach you how to pay attention to how you feel when you are moving, so you get more out of each and every workout.
Tune In
Our approach is rooted in accessible strength training, but that doesn’t mean we take it easy. With expert guidance and a motivating group atmosphere, you’ll challenge yourself and grow in ways that matter.
Train Hard
Haven is grounded in community. We believe that when you prioritize yourself, you can BE KIND to both your body and the people around you. It’s strength with heart—and it’s what sets us apart.
Be Kind
