"Reya is an exceptional therapist. She has a unique ability to listen to what I am saying verbally as well as what I show in a nonverbal fashion. She does not judge but instead uses gentle and effective guidance. She has empathy for me and the situations I have created or that have happened to me within my life. I immediately connected to her and have been working with her for about a year now. My situation was one of trauma, abuse, loss and addiction that brought me to her." - Tracy
