Kadeshia Jackson, LMFT-A
Hi, I am Kadeshia Jackson, a Licensed Marriage and Family Therapist Associate (LMFT-A) at New Dimensions Day Treatment Centers, where I work with adolescents and families navigating a wide range of emotional and behavioral challenges. My clinical experience includes working with diverse populations, from individuals in inpatient settings for eating disorders to those managing mood and anxiety disorders.
My approach to therapy is rooted in Structural Family Therapy, Solution-Focused Therapy, and Cognitive Behavioral Therapy (CBT). I view challenges through a relational lens, helping clients understand how family dynamics, patterns, and communication styles impact their overall well-being. At the same time, I focus on building practical skills and identifying strengths so clients can create meaningful and lasting change.
I am passionate about creating a space where clients—especially adolescents—feel heard, supported, and understood. I believe therapy should be both collaborative and empowering, meeting individuals and families where they are while helping them move toward healthier relationships and improved emotional functioning.
At the core of my work is a commitment to being someone my clients can rely on—especially in moments when they most need to feel seen and supported.
