what kind of jobs can i work with a degree in gerontology and minor in psychology?

I have been and am still in your position, and I've recently graduated... yikes.  Anyhow.

If you're interested, look up an MEd in Counselling for Adults.  It'll give you an opportunity to become a counsellor in different areas, such as school environments, hospitals, etc.  Otherwise, if you're interested in a much more research-based route, perhaps you'd like to go into clinical research for an MSc.  In this aging population, studies on memory/learning in elderly folk are increasing.  Other studies include rehabilitation of stroke patients and elderly folk incurring trauma.  I'm not sure if it's possible, but you may also be interested in therapy?  It would fall under a similar field as MEd in Counselling, but the title may be different.  And then of course, there are healthcare professions: nursing, PSWs, occupational therapy, physical therapy, med school.  Gerontology is a growing field, given the increased age of the general population.

Oh, and you have the option of not pursuing a job in either field.  Some people find that their interests lie far outside their degree and do well.  Like... pursuing an MBA if you were interested in business.  I knew someone who pursued pharmaceutical chemistry in their undergrad, decided it wasn't worth it and became a CA afterwards.  Now, she's managing accounts for a large pharmaceutical industry.  Go figure.

Sky's the limit.  The hardest part is narrowing it all down and following through.

Best of luck.

Any job really - most graduates get a job that is totally unrelated to their degree.

Management will be interested in other skills that you have learnt during your degree like time management, workload management, research and marketing skills.
