Our story

At Telos Strength & Conditioning, we believe strength is one of the greatest investments you can make in your health. That’s why Shaun and Karen Hazelton founded Telos in 2017—to help busy adults build lifelong strength through expert coaching, personalized training, and sustainable habits.

We don’t believe in quick fixes. We believe in building strength that lasts a lifetime. We’ve learned that lasting results come from learning to move well, building muscle with purpose, and following a personalized plan that evolves with you over time. That’s why every program at Telos is written by the certified coach working directly with you—not selected from a generic template—so you can continue making meaningful progress for years, not just weeks.

The name Telos comes from the Greek word meaning purpose or ultimate aim. To us, it represents training with intention. Every client has unique goals, and our mission is to help them build the strength, confidence, and healthy habits needed to achieve them.

The name also carries deep personal significance. It was the name of Shaun’s late father’s boat. Shaun learned the value of hard work, discipline, and coaching from his father while spending countless hours together in the weight room. Those experiences shaped not only his passion for strength training but also his belief that expert coaching has the power to change lives. Today, that philosophy continues to guide everything we do at Telos.

Whether your goal is to build muscle, lose weight, move with less pain, improve bone health, increase energy, or stay active as you age, our team is committed to helping you build lifelong strength through expert coaching, personalized programming, and a welcoming community that supports you every step of the way.

At Telos, we don’t just help people get stronger—we help them build the strength to live well for a lifetime.
