Welcome to Shift, an audio letter from clinical psychologist Dr. Sean Sullivan.

Each post will teach you how to shift yourself into a better state of mind, anytime.

Shifting will give you a fresh look at your relationship to your mind.

It opens your eyes to how much control you can have over your life experience.

Shifting works very well for most people.

In two years of pilots conducted at University of California, Santa Cruz (UCSC) over 95% of surveyed OnePerfect app users were able to shift into a better state of mind.

UCSC’s Counseling and Psychological Services (CAPS) now provides OnePerfect to UCSC’s 20,000+ member community.
