TESTIMONIALS

“Words cannot express the gratitude I have for Karie and the amazing work she has done with my daughter. My daughter had been diagnosed with exercise-induced laryngeal obstruction (EILO), and, as a national caliber runner, this was very distressing to deal with - her performances were being affected, and the stakes felt high with her dreams of running at a D1 program in college. We had already been to a speech pathologist, which had been helpful, but still left my daughter with many symptoms to deal with, especially during intense training sessions. The difference between the first speech pathologist and Karie was night and day. Karie is at the forefront of research and took a cutting-edge and innovative approach with my daughter. She is also a great educator and takes the time to explain the diagnosis and her methods, which made the process very approachable for my daughter. The results were remarkable! My daughter improved rapidly, ran all of her races with zero breathing issues, and had amazing performances to match! She is in control of her symptoms now and no longer fears hard workouts or races, knowing she has the tools she needs. I can't thank Karie enough - she helped my daughter bring back her joy and confidence in running and life as an athlete!"
