Hi, I’m Julia.
Certified Personal Trainer & Wellness Coach
What I love about fitness is that it doesn't have to look the same for everyone. Your journey will be unique to you. Fitness is personal. It should be empowering and you should continue to improve and evolve.
I'm Julia Haeffele (pronounced hay-flee for those curious!). I coach people like you who want to strive to be better, set goals and conquer them, understand and embrace overall wellness. Fitness and wellness have been something I've fallen in love with over the years and I'm passionate about helping my clients find that enthusiasm for it as well.
