Kaleigh grew up in a family full of avid athletes, fitness enthusiasts and dancers’, so being active has always been a huge part of her life. She began teaching dance and junior golf in her teens and continued throughout college at the University of Kansas, where she earned her degree in Strategic Communications.
When Kaleigh moved to Los Angeles in 2005, she was introduced to yoga. She quickly realized the profound physical and mental benefits that could be achieved with a regular practice and became hooked! As she continued deepening her yoga practice, she became more confident of her true calling in life – to leave the corporate world and get back to teaching.
In 2008, Kaleigh completed her 200-hour yoga alliance certification through YogaHop in Santa Monica and soon after, her Certified Personal Trainer certification through the National Strength & Conditioning Association, and her Nutritional Coaching certification through the Institute of Integrative Nutrition. Since then, she’s continued to immerse herself in studying the fundamentals of fitness, nutrition, and yogic philosophy with some of today’s most knowledgeable individuals.
Kaleigh’s clients and students range from celebrities and professional athletes to those individuals battling ailments or just trying to stay healthy. After nearly 10 years in Los Angeles, Kaleigh relocated to Dallas, TX in March of 2015. In addition to her extensive private clientele, you can find Kaleigh teaching regular yoga and fitness classes at several studios in Dallas, as well as Retreats across the globe. She recently added residential Real Estate agent to her resume as well. Kaleigh is an ambassador for Lululemon, Tory Sport, Manduka, and Carbon 38.
