I am 28 years old. I graduate with my undergrad degree in a week. Spent 3 years in college for business at 18, didn't enjoy it, worked construction or a few years and decided to go back for a psych degrees. Worked the past two years at a substance recovery center and a recovery living home while volunteering at treatment centers and going to school. I would think most people applying for clinical are older than 22, adds some maturity.
