Hi, my name is Sean Colvin

I'm the owner and lead psychologist at Grey Psychology. I derive meaning from my family, my friends, my dog, and my clinical work. My core values include truth, authenticity, kindness, integrity, and service. I strive to embody these values in my day-to-day life and in my work with clients.
