Sarah Seth

MBA, HKC: co-founder, managing partner

Sarah was born in Paris but grew up in Cote D’Ivoire (her country of origin) and France until moving to the USA in 2008 to continue her studies. She became a strong advocate for fitness and wellness after she decided to adopt a healthier lifestyle six years ago, which resulted in a significant weight loss and drastic improvement in her health and wellbeing. Sarah was introduced to kettlebell training and the health and wellness industry by her husband Glenn in 2013 and it automatically turned into her passion. Having witnessed the life-changing effects of kettlebell training, she was inspired to use her business management background to assist her husband in growing their family business and sharing the tremendous mental and physical benefits of fitness training and massage therapy with their community. Sarah holds a bachelor’s degree in Business Administration from Temple University and a Master of Business Administration from University of Maryland University College. She is also a Hardstyle Kettlebell Certified (HKC) Instructor. She loves traveling and discovering new cultures with her family and is dedicated to raising healthy, happy kids.
