Who We Are

Founder and CEO | Board Member

Olivia is a life-long yoga practitioner and has been teaching yoga since 2003 having studied with many master teachers around the country as well as in Rishikesh, India. Her education for teaching segments of the population that are at-risk for Post Traumatic Stress and Vicarious Traumatization began by becoming certified in Trauma-Sensitive Yoga under Yoga Warriors International.

She started working with veterans who struggle with Post Traumatic Stress and active military specifically before bringing this work to first responders.


While living in Los Angeles, Olivia adapted her offering of yoga to veterans to fit the first responder population by working directly with the Los Angeles Fire Department and department psychologist, Dr. Robert Scott. From there she taught weekly yoga classes at the Los Angeles Fire Department (LAFD) Training Center, as well as presenting training on yoga and the neurological system for LAFD’s Peer Support Team, and special workshops for high-ranking command staff of the Los Angeles Police Department (LAPD). She continues to work with LAPD’s Behavioral Sciences Services by partnering for special training events including The Smart Detective for International Association of Chiefs of Police.
