Trauma, in its many forms, creates a barrier to joy. We endure symptoms and work hard to adjust, but sometimes it’s hard to manage. Many people develop instinctive coping skills to survive, and yet, these survival skills create residual anxiety and depression. Each can lead to isolation. No one should be alone with these experiences. I hope to share my knowledge to help you manage your trauma. I’m an eclectic counselor, former teacher, and full-time empath trained multiple modalities. My background helping others has created a noticeable enthusiasm to connect and share in my client’s story of growth and change. Cognitive behavioral therapy, dialectical behavioral therapy, mindfulness-based cognitive behavioral therapy, motivational interviewing, and trauma therapy have been successfully employed in my four years of counseling, and I look forward to sharing these approaches with you!
