CARMELITA HORNE, Licensed Marriage and Family Therapist #46660
Hello,
My name is Carmelita Horne. I am a Licensed Marriage and Family Therapist (LMFT), a Licensed Professional Clinical Counselor (LPCC), and an AAMFT Approved Supervisor. The vision for Positive Change Counseling Services first began during my graduate training at UMass Boston, from which I graduated in 2000. Over the following decade, I dedicated myself to deep personal and professional growth—cultivating my clinical confidence and competence through impactful work at the Boston Area Rape Crisis Center, Napa Rape Crisis, and the River Oak Center for Children.
In 2010, I proudly opened the doors to Positive Change Counseling Services. Over the years, my deep foundational interest in trauma recovery has naturally merged with the therapeutic care of couples. This passion continues to drive my work as I complete my formal doctoral education to obtain a Doctorate in Marriage and Family Therapy (DMFT).
I am deeply committed to serving individuals who have been marginalized or belong to minority communities. My primary goal is to create a secure, affirming space where you can safely explore your authentic self, facilitate deep recovery, and experience lasting healing. I look forward to walking alongside you on this journey.

CARMELITA HORNE, Licensed Marriage and Family Therapist #46660
My name is Brittany Kohlberger. I am a licensed clinical psychologist and one of our supervisors here at Positive Change Counseling Services. After completing my pre-doctoral and post-doctoral training in the Detroit area, I relocated with my family to California in 2016 and have been with our practice since 2017. While I have specialized in treating kids, adolescents, and their families throughout my career, I have expanded my skillset and therapeutic practice to include adults and couples. Utilizing a foundational cognitive-behavioral approach, I strive to work with my clients to develop an individualized, and often integrative, treatment plan. I enjoy supervising our associates and participating in the care of even more families at Positive Change.
