Core Dynamics Staff
Jim O’Hagan
Owner/Head Fitness Coach
After struggling to find a facility that met his expectations Jim opened Core Dynamics in January 2006. “The fitness industry is constantly being devalued due to poor management and a lack of serious professionals, which lowers a members expectations of their fitness experience. People are led to believe that what makes a great fitness club is the size of the facility and how much equipment you can fit into it. I believe there are many factors that go into a great club… but it all starts with a great staff”. With a degree in exercise science, countless certifications and almost 25 years of experience, Jims’ passion for knowledge, along with his desire to assist people in reaching their fitness goals continues. “Strength for Life is more than a company slogan for me…it’s a philosophy that guides me every day."
