Meet Claire

Claire Shorenstein is a Registered Dietitian and Board Certified Specialist in Sports Dietetics (CSSD). She received her clinical training at Montefiore Medical Center, where she continued to work as an inpatient dietitian for several years. There, she counseled patients with a variety of chronic medical problems, including diabetes, renal disease, cancer, obesity, HIV/AIDS, liver disease, and heart disease, on what to eat to manage symptoms and improve health.


Claire always knew that her heart was in sports nutrition, and so she left the clinical setting in 2016. Since then, she has worked in private practice helping everyday to elite athletes achieve their performance and health goals.

Sports and Personal Interests 

Claire first fell in love with running as a member of her high school’s cross-country running team. She was a middle-of-the-pack runner and never considered herself much of an athlete, but found joy in movement and competition. After a long break from running, Claire discovered distance running in her 20s while living in London and the sport literally changed her life. Training for her first marathon connected her to her husband. Competing in subsequent endurance events inspired her to pursue a career as a Sports Dietitian, going back to grad school (again!) at the age of 30. 


Over the last 20+ years, Claire has competed in numerous solo and team events from the 5km to 50-mile distance. She particularly enjoys trail running and has completed a number of trail ultras and marathons, including The North Face DC 50k, UTHC 65kJFK 50, Sean O'Brien Trail marathonRodeo Valley 50k, Mt. Tam 50k, and Canyons 50k. Claire also has competed in 10+ road marathons, including two Boston-Qualifying times. Other running accomplishments include finishing the Boston Marathon in 2013 and 2014placing 2nd in the female relay division at the 2016 Big Sur International Marathon, and winning 1st place in the female relay division at the 2013 NYC Triathlon (2nd place in 2014 and 2015). 


Originally from Santa Cruz, California, Claire loves to travel and has an eclectic background. She attended Yale University, receiving a B.A. in Humanities and a M.M. in Oboe Performance. After more than seven years in the corporate world and a year-long solo trip throughout South America, she switched career paths to pursue her longstanding interests in nutrition, running, and helping others to optimize their health and performance. Her corporate background allows her to recognize the challenges that many of her clients face in maintaining a healthy lifestyle. As a runner and coach, she also understands the athlete mentality, the crucial role that nutrition plays in preventing and recovering from injury, and how to help individuals safely attain their health and fitness objectives. 


Claire spent nearly 15 years (collectively) living in NYC and now is back in Santa Cruz, CA with her husband and two young girls. She loves to run in the redwoods and on the beach, hunt for sea glass, garden, and do arts & crafts with her "free time."
