James is originally from New York and has lived in Fernandina Beach since December of 2016. After growing his chiropractic practice with his wife, James has partnered with Laura Porter to offer you Personalized Performance, Amelia Island’s premiere personal training experience.
James has been involved in the health and fitness industry for 15 years and has worked with clients from the age of 6 to 94 years of age. He has worked for corporate fitness clubs, including Retro Fitness and Lifetime Fitness, and has 10 years of private personal training experience. He has competed in 15 natural bodybuilding competitions, with 5 of those at the professional level. Aside from bodybuilding, James has also participated in road races, ranging from 5ks to a full marathon and two ultra-relays. 

James is a passionate and driven individual who truly loves sharing the gift of movement and fitness with his clients. He offers a uniquely comprehensive approach to individualized wellness due to his broad exposure as an athlete throughout his life. A series of two knee surgeries before reaching college became the catalyst for him to pursue a career helping improve how people move. James adheres to the philosophy that the human body must be able to adapt and overcome the physical, chemical, and emotional stressors that each of us encounter every day. His approach to success includes a holistic view of personal health that weaves chiropractic adjustments and daily mobility exercises, such as stretching and foam rolling (aka “spinal hygiene”), to preserve our physical body, layered with a well-planned strength training routine to improve our resilience to future physical stress. He helps his clients address the chemical stressors by making appropriate nutritional recommendations and addresses the emotional stressors by helping with life coaching strategies discussed during clients’ workouts. This 3-pronged approach is also the way all the trainers at Personalized Performance can help you make the changes in your current state of health to live an optimal life.

Marleah Dampier

  • Certified Functional Strength Coach
  • USA Weightlifting Florida Referee
  • 3-Year Top 4 Finisher Florida High School Girls Weightlifting State Championship Series

Marleah Dampier participated in flag football, track, and girl’s weightlifting at Fernandina Beach High School. Her main sport was weightlifting, and she attended state 3 times and placed in the top 4 each time. Focusing on weightlifting allowed her to learn to build strength and find a love of fitness and strength training. Additionally, participating in multiple other sports allowed her a different lens at which to view fitness and to address different types of physical abilities, such as cardio, power, and technical skills.

Marleah injured her knee in 2022. Following that she rehabilitated her knee through physical therapy and with a trainer right here at Personalized Performance. Since the injury, she has gotten back into strength training and exercise as a form of continued recovery. Overcoming this injury has taught her about the importance of listening to your body and gave her perspective about how difficult getting back into athletics can be after an injury. She hopes to help people in all levels of their fitness journeys, whether that means recovering from an injury, training to function better in a sport, or simply gaining strength and power for personal exercise and fitness goals.

She shadowed Laura Porter and Dr. James Antun to learn more about the technical side of personal training and gained a lot of knowledge from watching them practice with clients. She has also become a Certified Functional Strength Training Coach in preparation for working one-on-one with clients and enhancing her knowledge of the human body’s abilities. The heart of her experience lies in her own fitness and recovery journey, but she is looking forward to practicing with clients and gaining practical experience planning exercise regimens. Her focus is on training clients by building individualized workout plans tailored to their fitness goals, whether that is strength, performance, or functional fitness. Marleah hopes to help clients gain confidence in themselves and their bodies as well as grow their potential physically.
