Diana Kinsfather, Dietitian

Diana Kinsfather was born and raised in Aurora, Colorado.  From a very young age Diana was blessed with a wonderful foundation for health, including a mother who always served delicious, healthy, and balanced meals, and a sports-loving father who believed participating was better than spectating.  Swimming, golf, tennis, and softball filled the summers and basketball, volleyball, and skiing ruled the winter months.  For Diana, enjoying and appreciating the benefits of nutrition and exercise became second nature. 

Diana started working for Tribe Multisport in Scottsdale in September of 2006.  She competed in her first half-ironman that October and fell in love with the sport.  Recognizing the importance of nutrition to the cycling and triathlon community, Diana soon realized that what began as a hobby would turn into a career she would pursue with passion. 

Diana received her Bachelor of Science degree and her Masters of Science degree from Arizona State University; in both degrees her major field of study was Nutrition, with an emphasis on dietetics.  She completed her dietetic internship, also through Arizona State University, and received her Registered Dietitian Certificate in 2013.

Diana is the owner of Kinsfather Nutrition, providing diet and nutrition counseling and planning; she also works closely with Anna Sparks of Sparks Systems to help their common clients reach their personal health and fitness goals.  In addition to operating Kinsfather Nutrition, Diana also teaches Human Nutrition at Arizona State University and Mesa Community College. She and her husband Zack are the proud parents of a beautiful an active 18-month old daughter.
