I earned my Master’s Degree in Clinical Mental Health Counseling from Capella University and have spent the past 6 years as a Child Trauma Therapist. I am adoption competent and can provide attachment therapy to adoptive families. I truly love working with children and teens! Each child and teen are unique and I appreciate their individuality, interests, perspectives and experiences! I feel honored to help them overcome their troubles and obstacles. Outside of work, I enjoy spending time with my family! I love to travel around the world and embrace different cultures.
