Trevis Smith

Trevis Smith C.A.T.C.

Founder / CEO

Trevis’ career in addiction treatment and emotional healthcare has rewarded him for over 15 years. Before Trevis launched Profound Treatment, he served in many roles related to addiction treatment and emotional healthcare – including addiction & detox counselor, case manager, sober companion, clinical interventionist, and care planning & management.

Early in his career of addiction care, Trevis realized that a void existed: Personal/Individual Programs. He saw that one size does NOT fit all when it comes to treating a complex disorder that is simply known as “addiction” – and addiction is not simple. Trevis recognized that effective recovery plans must account for the sum of each person, including their life experiences and underlying neuro-emotional conditions. To help fill the void, Trevis opened the doors to Profound Treatment in 2016. Profound Treatment’s programs address the unique factors of every client, and our therapies dive deeper than a person’s surface behaviors (such as alcohol or drug abuse) to improve and save lives.

Trevis inspires others by sharing his story. Through his personal experience with adversity, he learned that recovery is possible in all situations and for everyone who needs help. Our clients benefit from building personal relationships with Trevis and the entire Profound Treatment family.
