Aleksandra Deren-Jones is a native of Gorzow Wielkopolski, Poland. An exemplary athlete, she won the Polish Track and Field Championships in the 400 meters twice, 800 meters eight times, and once at 1500 meters. She placed second in the 800 meters at the Junior European Championships, and represented Poland in the 800 meters at the European Championships three times.
After training and competing in Poland, she was recruited in 2000 by the University of Southern California (USC) to participate on their Women’s Track and Field Team while finishing her double degree in International Relations and Social Science. She was a part of the USC Women Track and Field National Championship team in 2001 and an All-American in 2002. After receiving her bachelor degree from USC in December 2003 she pursued her professional running career by joining the TC Montgomery Team, whose members included Olympic gold medalist Felix Sanchez, one of the top 400m Hurdle runners in the World.
In 2003 while competing professionally at 800 meters, Aleksandra began her career as a Certified Personal Trainer. She had numerous photos featured in OC Magazine and Runners World. Among her clients was star of the ABC hit comedy series Notes from the Underbelly, Mellanie Paxton, and Seth Adam Jones, who starred in numerous TV Shows and Films like Even Stevens and General Hospital.
After 8 years of training and living in Los Angeles, she married her husband Seth, moved to the east coast and focused her career solely on helping others in fitness. On April 4, 2011 Aleksandra gave birth to a beautiful baby girl, Lea Rose Jones.
“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.
