Sarah Seth

MBA, HKC: co-founder, Business Manager

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 a healthy, happy daughter.

Victoria Lanteigne


Victoria’s favorite aspect of yoga is the simple connection between mind, body, and breath. She firmly believes that a regular yoga practice can be an antidote to anxiety, stress, and negative thought patterns. Through yoga, Victoria encourages her students to connect with their deepest sense of self.  

Having grown up studying dance, Victoria took to yoga immediately in college at Michigan State University. She initially noticed the physical effects of yoga, but truly enjoyed the mental and emotional benefits that came with a regular practice.

Victoria received her 200 hour yoga teacher certification in 2016. Her style of teaching is warm and encouraging, suitable for beginners – but she can also help you nail that inversion or arm balance if that’s what you’re after!

Off the mat, Victoria enjoys cooking, hanging out at her community supported farm on Saturdays, and her day job – which entails working to improve health and wellness through the built environment.

Simone Egwu


Simone began practicing yoga after years of college sports. In yoga she found peace that hadn't been replicated in any of her other physical pursuits. The mindfulness of yoga practice provided a foundation to cope with her anxiety and depression and brought her to a place of gratitude and presence. She believes that a strong connection between mind and body enables us to appreciate the gift of each present moment. A D.C. native, Simone hopes to share the light and solidarity of yoga with her community and her students. She teaches a slow-burning, earthy flow with plenty of soul and always, always pigeon pose.
