I have my BA in psychology and currently work in a mental health program for a non-profit. I've been here for 3 years and love it. I recently applied for the MSW program at sac state due to working in this field. I think it's great you are considering working for a few years to make sure this is the field for you especially because a lot of masters programs want you to have paid work experience. I am a community mental health worker if that helps with your job search.
