Operations Manager & Nature-Connected Coach

Lauren grew up surrounded by strong women. She spent several summers of her youth at an all-girls camp in Maine, where she learned self-reliance, perseverance, strength and a strong sense of self.  As a woman, she finds it incredibly important to support other women in becoming the best version of themselves. Lauren graduated with a degree in Outdoor Leadership and Education, and worked for several years as a wilderness guide, specifically with girl’s aged 13-18.  Over the years, Lauren realized how important it was for young women to have strong female role models and to love themselves in order to grow up to be strong independent women. She has always seen the outdoors as a place of freedom, serenity and great challenge. Lauren uses nature as a tool to reconnect with her clients, in an environment bigger than themselves.  She explores deeply with her clients to identify what has been holding them back from making meaningful changes in their lives, and inspires them to discover for themselves what is needed to become that change. Lauren offers private coaching, workshops and group accountability coaching. She also collaborates with other teachers, coaches and professionals in the Health and Wellness field, to offer a one-of-a-kind holistic approach, which sets up her clients to take on the world as strong, successful women.

Aeryk is a lifelong athlete, originally from North Georgia.  He developed his passion for training while working with friends, to help them pass the Navy physical readiness tests.  This eventually led him to become a Command Fitness Leader in the Navy for seven years, with a focus in cross training and functional fitness.


He is not only passionate about being fit, but leading a healthy lifestyle as well.  This lifestyle saved his life in 2017, when he discovered he had a rare heart condition that would have caused a heart attack if he was not physically fit.


This drives him to help you become fit and healthy, in both mind and body.
