Hello, I’m glad you stopped by.

I’m Sean Sullivan, the above-mentioned psychologist, and a humble Shift Therapist.

In each Shift, we take a rejuvenating dive into presence as we explore and shift our minds together.

‘Shifting’ will give you a fresh look at your relationship to your mind and open your eyes to how much control you can have over your life experience.

It works very well for most people. In over two years of pilots, over 89% of surveyed OnePerfect Shift app users reported being able to shift into a better state of mind by completing a Shift.

If you practice shifting consistently for a month or so, it typically starts to become easier to strategically shift your state of mind whenever you choose to.

You’re always welcome to shift with me!



"Dr. Sullivan's digital tools are like having a psychologist who is your close friend with you every day. It's so helpful and it works."

— Marta Wegorzewska, Ph.D., Scientific Editor, Washington University

“Dr. Sullivan is a game changing voice in the psychology of peak performance."

Mark Sanchez, NFL Quarterback, 2009-2018

“This will be a norm in organizations and education within a few years. There is a massive need for this."

— Paul Marcille, PhD., President, California Psychological Association, 2020
