"Starting my journey with Jason Stevenson in November of 2013 changed my life. I saw myself in a photo that completely disgusted me and that was the day I made an appointment with him. When the day of the consultation came I was so nervous and all I could think was that I am way too fat to exercise.  He quickly changed my outlook.  When I met with him he pulled up two yoga balls and there we sat where I laid it all out about my past diet fails and lack of motivation. The rest is history. 

Jason has guided me through a 60 lb. weight loss, changing my entire outlook on food and “diets”, conducted weekly weight checks and measurements, personally supporting me in my new goal of 5ks, designed customized work-outs for our training, in time guiding me to be comfortable in group classes, and supporting my newfound interest in weight training; all the while focusing on on the mental aspect of the fitness journey.  

If you want a trainer who will be supportive in your victories (no matter how big or small) and bumps (there will always be some: like weight gains and plateaus) choose Jason to be a part of your team and journey towards a healthier lifestyle."

After my second bikini competition, I found Ashley on social media in December of 2014. I was interested in working with her primarily because of her experience with flexible dieting. 


Immediately after contacting her, Ashley's sense of enthusiasm about being my coach was second to none. Ashley's dedication and work ethic completely circumvented the living distance between us, and never allowed it to be an obstacle to our progress. As soon as my competition preparation started, it was clear the amount of time Ashley put into making my meal and workout plans. Every single aspect was customized for my body and what I was hoping to achieve. Ashley is always readily available to answer any question that I might have, at any hour of the day. 


Whether it be for competition prep, or maintaining a strong and healthy lifestyle, I will be keeping Ashley in my corner for a very long time!"
