About Katy
Hello! I’m so glad you’re here. The creation of Radiance Healing is the culmination of over 25 years of professional experience and navigating my own healing journey.
Professionally, I have been a Certified Child Life Specialist since 2001, specializing in working with all members of a family to promote coping and resilience in a variety of stressful circumstances. For 12 years, I had the privilege to support many families in the Pediatric Oncology department at Seattle Children’s Hospital, and later worked in Gastroenterology, Surgery, and Radiology at Swedish Medical Center. Additionally, I have many years’ experience as a Parenting Educator and have been a Certified Parent Coach since 2015.
For 7 years, I was a professor of Child Development and Family Science at Central Washington University, serving as the director of the Child Life Specialist program and engaging in research related to child, teen, and parent grief. My areas of teaching expertise include child development, parenting, and the application of brain science to parent-child attachment, stress and coping, and promoting resilience for individuals, families, and in educational and healthcare settings.
Katy Tenhulzen
FOUNDER, RADIANCE HEALING
“My love for fellow humans navigating the ups and downs of life drives me to provide compassionate support tailored to each unique client and family.”

My therapeutic approach has long been grounded in brain science, play-based learning, expressive activities, and a connection to mindfulness and embodiment practices to promote healing.
My own journey of physical, emotional, and spiritual healing inspired me to pursue additional training and certification in healing modalities, including the Safe and Sound Protocol, Reiki energy healing, and Energy Psychology. Radiance Healing also offers sound frequency and light therapy in Bellevue, Washington. The infusion of these practices supports signficant healing and greater wellbeing for my clients.
