Nikki credits her talent of achieving lasting results with the most challenging of cases to her education, love for learning and her own personal experience. She was a ranked competitive gymnast for 10 years before a spinal injury steered her away from the sport. After gymnastics, she moved forward competitively in track, cross country, dance and cheerleading where she earned the honor of state champion and went on to cheer with the national champion University of Kentucky Wildcats. 

In 37 Years, Nikki has endured more traumatic injuries and health issues as a result of her love of movement and sports than most people will encounter their entire lives. By 25, she was plagued with pain, injuries and limitations as a result of multiple car accidents and the wear and tear from 16 years of competitive sports. At 26, she was told by doctors she should never run again and that in order to become pain free, her only option was dangerous pain meds, injections and stopping most of what she loved. Instinctually, she knew that couldn't be the case. Nikki believed in the bodies inherent ability to recover and was determined to heal herself both inside and out as naturally as she could. Today, Nikki is pain free and doing everything she loves including running, cycling, skiing, yoga and dance. 

Nikki developed and fine tuned FitLogik as a result her quest to be strong and healthy again. It is her answer for finding simple solutions to seemingly complex problems. By combining science, experience and wisdom, Nikki has cultivated an incredible ability to meet people where they are and find the easiest road to get them to where they're going. She brings compassion, enthusiasm and inspiration to each of her clients while offering a logical, systematic approach for achieving results often thought to be far from reach. Even though Nikki enjoys working with clients of all kinds, she has a special love for working with pre and post natal moms as well as athletes of all levels.
