I view PMPs as those who have been in the project management field that want to showcase their knowledge and dedication to the profession, whether project analyst, project coordinator, or project manager. There are plenty of project managers that do not have certifications and are very good at their job, and there are plenty that are not and the same for those that do have certifications. Just like a degree, it will get you in the door, but you must prove you are good at what you do after you get hired.
I do recommend obtaining certifications and furthering education, it helps prove you are dedicated to your craft; does not mean you are good at what you do, only your work will prove that.

Project management is a growing field and there are plenty of certifications, certificates, and education opportunities, but remember…Not Every PMP is a Project Manager!
