Brent has engaged with clients in individual, group, couples, and family sessions. Brent has a strong belief that education, not only traditional schooling, but also learning about one’s symptoms and the effectiveness of treatment modalities, is vital for clients to feel confident the changes they make will be lasting. In 2004 after consulting with various programs and schools on licensing compliance, Brent opened a boarding school in Louisiana for teens. Brent takes great pride in the graduation rates and outcomes for those students while he remained involved in the school. Although he enjoyed Louisiana and the people, the yearning to be near family and back out west, led Brent to Colorado after he completed a Juris Doctorate at Louisiana State University.

Brent has found this education as highly complementary with his love for mental health and he has used both skills as a mediator. Brent has spent the last 9 years working in mental health crisis which has reinforced his training in CBT, Solution Oriented Therapies, Family Systems, and Trauma Informed Care. Brent has also maintained a small private practice specifically focusing on families, couples and adults who are experiencing issues with changes in life and are seeking clarity and change around new life developments.
