    Growing up I was never the fastest or most athletic kid in the class, but once I started training regularly and optimally my performance improved. Fitness became a passion for me at that point and became so enjoyable and routine that I began to recruit friends and family to join the movement. This all carved the path to where I am today - coaching others and helping facilitate their growth and development both in health and recovery. I’ve now been at FT for 10 years and looking forward to many more! My work feels impactful and important, and I genuinely feel my knowledge is enriching the lives of others. I’ve developed close professional relationships with both clients and coworkers, and that rapport helps keep our FT family strong and committed to each other.

    in my free time I like to
    Spend time with my significant other, push myself with challenging workouts, try different restaurants, and play video games with online friends.

    I joined the Fitness Together Southpark team in 2019. Originally from Vale, North Carolina, I attended UNC Charlotte where I obtained my Bachelor of Arts in Psychology. My fitness journey began while in college and culminated in 2013 when I lost 60lbs and decided to dedicate my life to helping others achieve their goals. I am a NASM certified personal trainer, who has developed training programs specializing in speed and agility, boot camps, TRX focused programs, general fitness programming, and large and small group exercise classes. My drive is to motivate and help others achieve what they thought was impossible. My favorite part of training is helping others along their fitness journey and seeing them surpass the goals they set for themselves. My favorite part about training at Fitness Together are the clients I get to work with every day. Seeing their struggles, their will to succeed, and their accomplishments motivates me as a trainer and a person.

    in my free time I like to
    Participate in competitive runs, play golf, read, and be around friends and family.

    I am a personal trainer and former touring musician. I discovered a love for music at an early age and began honing my skills as a bassist. I've toured the country for performances and shared the stage with some big name artists! Despite my success in music, I felt the desire for a new challenge. I pivoted into fitness and became a Personal Trainer. Drawing on my own experience with discipline and perseverance, I am dedicated to helping clients achieve their fitness goals whether in the form of strength, weight loss, or just feeling better in their skin. I bring a dynamic approach to my work as a fitness professional. I believe that anything is possible with the right mindset and training, and am committed to helping clients realize their full potential.

    in my free time I like to
    Travel with my wife-to-be, attend and play local concerts with my current band (Simplified), and conquer my own personal health and fitness goals.

    • Masters Kinesiology: Strength and Conditioning

    Though I was heavily involved in competitive sports for years, my love for fitness truly developed with my passion for training others. I find it highly rewarding to help people progress through physical and mental challenges, and every improvement is a win in my book. When the pandemic hit and gyms closed, I gained at least 30lbs and lost a great deal of muscle. I also struggled to maintain confidence in myself and began to doubt my abilities as a trainer. I had to dig deep to find the courage and motivation to get back on the horse, and now I make that same confidence available to my clients. I specialize in Corrective Exercise and Athletic Strength and Conditioning. I enjoy working with people of all fitness backgrounds, and I strive to create a safe and encouraging space to challenge yourself and reach your goals.

    in my free time I like to
    cook, spend time with friends, work on puzzles, and play with my dog Gustavo!

  • I started working out after having breast cancer and heading to osteoporosis. My primary goal with FT was to increase bone density. I now have normal bone density.

  • Friendly people who care about helping you achieve your goals. FT helped me prepare to hike the Appalachian Trail at age 65. If you have the will, FT will show you the way.

  • I have been working out at FT for a couple of years and it has made a dramatic difference in my health. I no longer need hip surgery and I am able to dance and hike again.

  • The high quality training and nutrition advice at Fitness Together has helped me reach my fitness goals. I’ve lost 20 pounds and have a BMI of 22.8!
