Dr. Lyanna Diaz


About Me

I am a clinical psychologist licensed in South Dakota with 3 years of experience working as a therapist. I received my doctorate from George Fox University, a Christian university in Oregon. There I gained knowledge of how to incorporate my faith into the therapeutic relationship. My faith is very important to me and I love being able to incorporate it into the work I'm doing, when appropriate. I have worked with clients with a wide range of concerns including depression, anxiety, relationship issues, and PTSD/trauma. I also helped many people who have experienced emotional abuse.

My counseling style is warm and supportive. I believe in treating everyone with respect, sensitivity, and compassion. My approach combines cognitive-behavioral, humanistic, and interpersonal counseling. I will tailor our dialog and treatment plan to meet your unique and specific needs.

You may find it helpful to know that I have experience being the client in a counseling relationship so I know the worry about finding a good fit. I am a person who needs to know I can say anything to my therapist and not feel judged. I need to feel understood, validated, and able to be myself. If this is the kind of relationship you would like to have with your therapist too, then I think we will be a good match.

It takes courage to seek a more fulfilling and happier life and to take the first steps towards a change. If you are ready to take that step I am here to support and empower you.

I look forward to working with you!
