Is healthcare administration a good career to find a good job ?

The health administration is certainly a secure job, and paid pretty well, but is often considered a very stressful job.

Consider this

Times are tough, the demands are tough, and you're seeing the public at its worst - the sick, depressed, frustrated, mentally or verbal abuse. If you do not manage an environment of high tension, so, you may want to consider other options.

However

The best step for you would be a Masters in Health Administration (MHA). I believe that the health science and biology are very good options.
