Nicole Farha

WIN Group Fitness Instructor

Nicole comes to the WIN with 7 years experience teaching group fitness at athletic clubs and studios along the Northshore of Chicago. Prior to entering the wellness space as a fitness instructor and yoga teacher, she had a career in medicine. Seeking to truly embrace the “healer” within her, she left medicine and approached wellness from an entirely new perspective. As a former dancer she found a way to combine her passion for health and wellness with dance and got certified to teach a dance fitness format called WERQ. From that day, a new path towards health and JOY was found. She added on certifications in yoga, strength, children’s yoga, Reiki and meditation. She is passionate about providing as many paths towards well being as she can for her students, seeking to integrate fitness, nutrition, and mindfulness into their daily routines.

Nicole’s guiding philosophy when teaching is this: “Whether I am teaching a handful, or a 100 people in a class, there is always one person in that room who was meant to hear my message and share my energy that day; and that may be the moment that can shift them forward on their journey. That is my purpose in teaching and connecting. To quote Glennon Doyle, I am here to help people on their path towards their “truest, most beautiful self’.

Nicole is a California native that currently lives in Glenview with her husband, two kids, and their gigantic, quarantine-acquired cat, Grayson. When she is not teaching, training, or dancing, she is a writer, speaker, storyteller, mental health advocate, and a “forever student”, always looking to deepen in and understand the “why”.
