Keith Sullivan, MA, LMFTA

Professional Background

  Keith Sullivan is a Licensed Marriage and Family Therapy Associate, dedicated to walking alongside individuals, couples, and families through life’s most complex challenges. 


Before entering clinical practice, Keith spent over twenty years serving individuals and families in cross-cultural and crisis settings, including substance abuse rehabilitation and post-war trauma. His global background shapes his compassionate, systems-oriented approach to mental health, helping clients foster resilience, relational healing, and long-term personal growth.



Therapeutic Approach

  Keith views human behavior and emotional well-being through a relational lens, recognizing that individuals are deeply connected to the relationships and systems around them. His clinical approach integrates evidence-based modalities, including Acceptance and Commitment Therapy (ACT) and structural family therapy, tailored to each client's unique goals.


Keith prioritizes creating a safe, compassionate space, and he also believes real healing requires more than supportive hand-holding. He gently applies constructive pressure and accountability, challenging clients to step past comfortable patterns, take ownership of their growth, and put practical tools into action.


Keith is certified in Gottman Method Couples Therapy and is a certified Prepare/Enrich Facilitator, helping couples strengthen communication, resolve conflict, and build lasting intimacy. In addition, Keith has a focused clinical interest in supporting individuals and families navigating bipolar disorder, helping clients cultivate stability, effective coping strategies, and strong support networks.
