About Nicole
​
My interest in nutrition started long before I became a Registered Dietitian-Nutritionist. Growing up I was a snowboard racer on the U.S. Junior National Team and traveled the world to compete. I realized the importance of proper fueling during these years, so when I left racing in 2001 I shifted my focus to my next passion, nutrition and helping others. My career began in 2006 after completing my B.S. in Nutrition from Cornell University and my dietetic internship at New York Presbyterian. My foundation was diverse, working in a variety of clinical nutrition settings, a top sports nutrition practice in Manhattan, and running a private practice on Long Island. I relocated to Colorado in 2010 to continue my career and advance my skills as a sports dietitian. I enjoy working with complex sport nutrition cases (athletes with medical conditions) as well as recreational and elite athletes looking to improve performance or change body composition. I enjoy my free-time mountain biking, snowboarding, cooking, and relaxing with my two dogs, Sol and Woody. I love planning my own sport nutrition too, which has been essential for strength and conditioning to stay strong and healthy during mountain bike season.

About Jacque
​
As a life-long athlete I am a firm believer that nutrition can make or break an athlete’s ability to meet their goals. 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. After earning a B.S. and M.S. in Nutrition, I got hooked on running marathons and completed 26 of them, including qualifying for Boston. In my 40s I started racing Ironman triathlons and completed 5 Full Ironmans and a dozen Half Ironmans (7 times on the podium). I've also finished ultra runs (50k) and cycling events (Double Triple Bypass). Now in my late 50s I'm increasingly focused on strength training and understanding the unique needs of ‘Masters Athletes’. I live in Summit County, CO where I teach skiing and work from home as a Sports Dietitian-Nutritionist. My passions include all snowsports, mountain & road biking, hiking, kayaking, dog rescue work, and relaxing at home with my husband and our rescue dogs.

Sarah Sullivan, RDN
About Sarah
My athletic pursuits began competing as a hunter/jumper equestrian rider. This spurred my love for competition which carried through to running cross country in high school, competing in several half Ironmans and triathlons in college, and racing as a cat 2 road cyclist. I grew up skiing and continue to enjoy both downhill and backcountry touring in my adult life. My more recent athletic focuses have been around XC mountain bike racing. In my pursuit for the podium and enjoying grand outdoor adventures, it became apparent that sports nutrition strategy is key to maximizing success. I began my studies in dietetics at the University of Arizona in 2014. I completed my Dietetic Internship in 2017 and worked in the clinical setting learning about various disease states. In 2019, I made my transition to the outpatient setting working in bariatric surgery, where I continue to practice part time today. I also completed my Bachelors in Science at Northeastern University in Psychology which provides me with unique qualities to offer an empathetic and holistic coaching approach. As a passionate cyclist, skier, runner and climber I understand the unique needs of an athlete. My goal is to help support your athletic pursuits by coaching you on how to properly fuel and achieve your goals.
