Diana Biciusca, Licensed Professional Counselor at LifeStance Health, helps individuals and couples across Tennessee navigate life’s challenges with compassion and evidence-based care. She supports adults and seniors seeking to manage symptoms of anxiety, depression, trauma, and mood disorders while fostering long-term emotional resilience and balance. Diana provides a safe, understanding space for self-exploration and growth, tailoring each session to meet the unique needs and goals of her clients throughout Tennessee. Diana works with clients on a wide range of concerns, including relationship challenges, life transitions, and trauma recovery. Using approaches such as Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Mindfulness, she empowers individuals to identify unhelpful patterns, build healthier coping strategies, and restore a sense of control and well-being. Her experience in both individual and couples therapy allows her to support clients in improving communication, rebuilding trust, and strengthening their emotional connections. Diana is especially passionate about helping individuals who are adjusting after recent psychiatric hospitalization, navigating court-ordered treatment, or completing disability paperwork. She recognizes that these moments can feel overwhelming and works collaboratively with clients to stabilize their lives, strengthen self-understanding, and move forward with renewed purpose. Her compassionate yet structured approach helps clients find clarity and confidence as they rebuild their sense of self and stability. In addition to her clinical expertise, Diana offers faith-based and Christian counseling for those who wish to integrate spirituality into their healing process. She also provides support to LGBTQ+ individuals, first responders, and military veterans, helping each person find strength and meaning in their journey.

Outside of her work, Diana enjoys raising and caring for her beloved Standard Poodles, which bring her joy and balance. She brings the same sense of empathy, patience, and dedication to her clinical work that she does to her personal life. Diana is honored to serve individuals and couples throughout Tennessee, providing professional, compassionate, and personalized care to help each person thrive.
