Nicole Rubenstein, MS, RD, CSSD, CDE

About Nicole
During the 1990s I was a competitive snowboard racer and traveled the world to do what I love most. I realized the importance of proper nutrition during my racing career, so when I retired from racing in 2001 I attended Cornell University to get my degree in nutrition. What better than to pair my love of sport with my love of food! I began my nutrition practice in New York in 2006, working in both inpatient and outpatient settings and eventually starting a private practice. I relocated to Colorado in 2010 to continue my nutrition practice and develop my skills as a sport nutrition professional. In addition to working full-time as a dietitian, I enjoy my free-time mountain biking, snowboarding, cooking, and playing with my two dogs, Sol and Woody. I love planning my own sport nutrition as well, which has been essential for strength and conditioning training to stay strong and healthy during mountain bike season.

Jacque Maldonado, MS, RD, CDE

About Jacque

I started swimming competitively at age 6 and essentially grew up in a swimming pool.  Skiing, hiking, cycling and tennis were also part of my early life. It seemed clear to me that eating habits made a difference to my performance in sports.  After earning a B.S. and M.S. in Nutrition, I started training for marathons and was hooked instantly.  I helped my fellow runners understand proper fueling strategies for distance running by giving talks and consulting at a fitness club.  In my 40's I started racing Ironman triathlons and completed 5 full Ironmans in a 10-year span. My 27 years of experience as a dietitian and 9 years as a sports nutritionist helped me feel strong while training and racing long distances. I now live in Summit County and teach skiing, coach swimming and work from home as a Health Coach and Sports Dietitian.  I enjoy travel, adventure and being outside doing the sports I love, followed by some rest and relaxation with my husband and our three rescue dogs
