I agree with Sky. My program actually offers two different business certificates, one based on MBA type work and one that is health care admin. related. These are earned by taking business electives instead of all psychology electives. This content has been invaluable. Many of us agreed that we could always learn the stuff we might have learned in a psych elective by taking seminars, reading, special practicums, etc., so we didn't feel we were sacrificing anything psychology-wise.

The only other thing I'd add (if no one else has) is to find out as much as you can about what it's like to go through a doctoral program beforehand. And make sure the field/opportunities it will offer you are what you want. It's a big change from undergrad, and also a change, albeit smaller from a master's program.

Good luck.
