“I really enjoy my workouts with Hunter. He is polite, professional, and works hard to customize a workout that works for all fitness levels. It can be intimidating working out with a trainer or going to a gym, but Hunter provides great coaching and motivation and is absolutely focused on making sure his clients are safe, but pushing themselves to the next level. There is no judgment from Hunter, he is simply focused on making you healthier and stronger. If you have thought about working out with a trainer, you won’t be disappointed in what Hunter can deliver.” – Delores Michelle Hannan


“I have been going to HFS for a few months now but have been working out with Hunter for about three years. He truly cares about your personal goals. But most importantly he is kind, professional, and motivating. We always have fun when we work out and work we hard while we are at it. Our class is at 5:30 am and he always shows up perky and ready to go and sometimes brings his dance moves. So if your looking to ease in to a fitness class or want to go hard straight out of the gate Hunter is the guy for you. He will not let you down.” – Torey Whitman


“I love taking classes with Hunter! He makes the workouts fun and mixes it up so you are never bored . I took the first 30 day challenge and lost 5 lbs and could really feel a difference. Now I’m continuing on with Hunter to reach my goals” – Renee Soule
