Clinical Psychologist

William P. Kooistra, PHD

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.
