Hailey Daniels Krey

Born and raised in Ogden, Utah, Hailey was born with the desire to serve and help others. Hailey’s motivation in writing “Smiley Riley – Arthritis In Motion” stems from her personal experiences of fighting Juvenile Arthritis since her diagnosis at the age of 15. As an active tennis player, Hailey fought to stay active and faced the setbacks with a smile. She came up with the motto Arthritis In Motion (AIM); which stands for living life to the fullest, despite adversity. Despite the setbacks of arthritis, Hailey worked hard to make her dream of playing college tennis a reality. With the help and support of doctors, coaches, trainers, friends and family, Hailey played tennis for Brigham Young University – Hawaii and Brigham Young University in Provo, Utah. She is married to the love of her life, McKay Krey, who is her number one fan and biggest supporter. Hailey continues to share her story and help other kids and teens affected by Juvenile Arthritis. She hopes that the story of Smiley Riley will bring hope and encouragement to all children fighting juvenile arthritis.

Hailey is an inspiration to all children with arthritis. Hailey was diagnosed at 15 years of age with Polyarticular Juvenile Idiopathic Arthritis and I have had the pleasure of caring for her as she has tackled arthritis head on with determination and strength. I have watched her take on the world during times of quiet disease and held her hand during times of flare. Hailey has always faced both these circumstances with determination and courage not allowing arthritis to control her. She instead controls her arthritis with strength and grace. I am been privileged to have cared for Hailey and all the wonderful children with arthritis who have such bravery and determination.
