Who We Are. What We Do.

Better Self Psychology is a youth-focused practice that provides psychological services to children and young adults. We aim to make therapy accessible and rewarding to engage with.

Our practice is built around a community of families, with the intent to provide clients with the skills, connection, and experiences that may otherwise be missing their lives.

Our team is comprised of highly skilled psychologists who provide consistent positive outcomes in a warm and caring environment.

Clear action requires clear thought. Our psychologists are here to discuss your challenges and help find a way forward.
