William P. Kooistra, Ph.D.
Clinical Psychologist

Welcome. I am Dr. Bill Kooistra, and I am a fully licensed Psychologist working in Grand Haven, Michigan. I have been providing psychotherapy for over twenty years to adults, adolescents, couples, and families. I provide confidential treatment addressing a wide variety of psychological issues and concerns (see services below).
My approach to psychotherapy draws from a variety of theories and models that seek growth and healing for the mind, body, and spirit. I intend for therapy to assist people in finding relief from psychological symptoms and struggles as well as developing a greater sense of meaning and engagement in their lives.
