Our team

Cassie Dimmick is the founder of Achieving Your Best, a wellness and fitness company she launched in 2007 with humble beginnings—meeting clients in coffee shops and building connections one person at a time. Her vision and dedication have since grown into a thriving 6,000-square-foot facility, established in 2017, where she now leads a multidisciplinary team of dietitians, personal trainers, physical therapists, managers, and administrative professionals.

Cassie holds dual Bachelor of Science degrees in Microbiology and Nutrition from Texas A&M University and a Master’s Degree in Nutrition from Texas Woman’s University in the Houston Medical Center. She completed her dietetic internship at the VA Hospital in Houston in 2001 and has spent the past 25 years working in the wellness and fitness industry.

Her professional credentials include Registered Dietitian Nutritionist (RDN), Certified Specialist in Sports Dietetics (CSSD), Certified Exercise Physiologist through the American College of Sports Medicine (ACSM-EP), and Road Runners Club of America Certified Running Coach. Cassie is passionate about guiding clients to lead their healthiest, happiest lives through personalized, realistic, and enjoyable approaches to wellness.

Outside of work, Cassie cherishes time with her husband and two daughters. She enjoys hiking, gardening, cooking, traveling, savoring great food and wine, and embracing the outdoors. Her commitment to a balanced and fulfilling life is at the core of both her personal and professional philosophy.
