Athena Kjell, MS, NCC, LPC, SAC - If you could shift just one thing in your life right now, just one... what would that be? Sometimes we get stuck in habits. Sometimes we believe the negative voice in our head. Fear and avoidance are blocks to living in line with your values. I'm here to come along side you to help you think in a different way so that you can be the best version of yourself. Whether you struggle with anxiety, depression, relationship issues, low self-esteem, addiction, trauma, guilt and shame, or lack of vision in life, change is possible. I approach therapy by taking your goals and challenging you to take action with manageable steps. I integrate various approaches, including Cognitive Behavioral Therapy, Behavioral Activation, Dialectical Behavioral Therapy, Mindfulness and Relaxation skills, Psychoeducation about shame shields and shame resilience, and Aroma Freedom Technique (optional). "If you're comfortable, I'm not teaching and you're not learning. It's going to get uncomfortable in here and that's okay. It's normal and it's part of the process" (Daring Greatly, p. 199). You do not have to be alone in your journey towards healing from life's hurts, habits, and hang ups. Can I be a part of that process?

I approach every client non-judgmentally and as my genuine, authentic self. I firmly believe that building a solid, trusting therapeutic relationship is the mainstay of counseling. I utilize a cognitive-behavioral approach to therapy with a person-centered orientation to my clients. I also use motivational interviewing to help unveil untapped potential. I am eager to work with adolescents and adults who are struggling with mental health and/or substance abuse concerns of vast range.
