Cassandra Pentzien, Ph.D
I created Pentzien Psychological Services with the goal of providing comprehensive and holistic mental health services. Through psychological assessment, I help clients learn more about themselves, including identifying areas of strength and targets for support. I enjoy working collaboratively with clients in individual therapy to identify and meet their own personal goals for success. I appreciate taking the time to get to know each client so I can better understand their background, needs, and plans for the future.
