Christina has been a member of the American Physical Therapy Association since 2007, and a member of the Texas Physical Therapy Association in 2011.

When Christina is not improving the wellness and mobility of her patients or mentoring residents, she is attending the games of her favorite Houston sports team, the Houston Dynamo.

Class of 2013 - Athletic Training Residency

Emily White, ATC, LAT

As a born and raised Spartan, Emily is a long ways from her original hometown of Okemos, MI. After graduating from Michigan State University in the spring of 2012 with a Bachelor’s Degree in Athletic Training, she discovered the sports phenomenon all the way down in Texas and sought out the unlimited opportunities to excel in the sports medicine profession. While her heart and soul are in Spartan country, she has grown to love what Texas has to offer. Between her strong personal background of participation in sports and her exposure to sports medicine as an athlete, her passion grew for sports medicine and wanted to make a difference in other people’s lives by helping those with a common passion for physical activity achieve their goals. Michigan State’s Athletic Training program is well known for manual medicine, which has been an aspect that Emily has grown to love in the treatment of her patients. She started her Texas adventure in Fort Worth in July 2012 to gain more experience, but had limited opportunity to practice her knowledge of manual medicine and she wanted to continue to better herself and strive for excellence in the profession. Between her experiences at Michigan State, empathy for athletes through her own mishaps, love for the athletic venues, interest in the clinical aspect of sports medicine, the eagerness to learn more from the rehabilitation aspect, and the motivation to continue learning to provide the best patient care, she sought out the opportunity to advance her knowledge and skills through the well rounded residency program that Houston Methodist of Sugar Land has established. While devoting her time to becoming a better clinician through the residency, she will also be advancing her knowledge by obtaining a Masters Degree from the University of South Florida in the Master of Medical Sciences Program with a Concentration in Athletic Training, which she will finish in the spring of 2015. While she will always bleed green, she is excited for the opportunity she has in Sugar Land to grow and continue moving forward.
