Membership in a professional organization is a positive step in your career path. We also look at that during the Dean Scholarship process. There are many organizations you can join based on your professional experience and background. If you are a registered nurse or physician assistant you already probably belong to your professional association or should consider doing so.
Philadelphia University has a student chapter in the International Association of Emergency Managers. You can join the University's chapter for $30 per year. This is an important network to establish and has many resources that you can use as a student.
