Aleksandra Deren-Jones brings a lifetime of elite athletic experience and a passion for fitness to her personal training practice. A native of Gorzów Wielkopolski, Poland, Aleksandra’s journey in sports began on the track, where she became a national champion, winning the Polish Track and Field Championships in the 400 meters twice, the 800 meters eight times, and the 1500 meters once. Her talent and determination took her to the international stage, where she placed second in the 800 meters at the Junior European Championships and represented Poland three times in the 800 meters at the European Championships.
In 2000, Aleksandra was recruited by the University of Southern California (USC) to compete on the Women’s Track and Field Team while earning a double degree in International Relations and Social Science. She was part of USC’s 2001 Women’s Track and Field National Championship team and became an All-American in 2002. After graduating in 2003, she pursued a professional running career with the TC Montgomery Team, training alongside world-class athletes, including Olympic gold medalist Felix Sanchez.
While competing professionally, Aleksandra discovered her passion for helping others achieve their fitness goals and became a Certified Personal Trainer in 2003. Her expertise quickly gained recognition, leading to features in OC Magazine and Runners World. She worked with a range of clients, including actors Melanie Paxson (*Notes from the Underbelly*) and Seth Adam Jones (*Even Stevens, General Hospital*).
After eight years of training and living in Los Angeles, Aleks moved to the East Coast, where she shifted her focus entirely to personal training. Her dedication to fitness took on an even deeper meaning with the birth of her daughter, Lea Rose Jones, on April 4, 2011.
Today, Aleksandra channels her elite athletic background and years of training experience into helping clients of all fitness levels build strength, endurance, and confidence. Whether working with professional athletes, busy professionals, or those just beginning their fitness journey, she brings the same drive and enthusiasm that made her a champion on the track.
Let Aleksandra help you reach your fitness goals and unlock your full potential!
—“There is no better reward than seeing a client getting fitter, losing inches and as a result getting his/her confidence back. My philosophy is simple: I love what I am doing and I am being rewarded for it. That is very gratifying.”

Reviews & Testimonials for Aleksandra Deren-Jones
I need someone I can trust and respect to challenge me and that is what I get with Aleksandra; it has made all the difference. Aleksandra is patient beyond belief and is always willing to go above and beyond to help me continue to move forward towards my goals. Aleksandra’s knowledge, commitment, motivation, and friendship have pushed me (and in some cases pulled me!) further than I have ever gotten on my own. Thank you Aleksandra and thank you Core Results for helping me gain confidence in knowing I can reach my goals!

As a business owner, I wasn’t sure my schedule could support the time commitment of training. But now, I can’t imagine not having Core Results on my weekly calendar. Aleks, my trainer, has been great. She keeps the workouts fresh and I’ve already accomplished my first triathlon.
