Project Management Certifications

I have a question for all, including consultants.  Is there a good project mangement certification that I could pursue?  My role is evloving and my limited knowledge of project management has reached it's limits.  So I am looking to skill myself up some.  

So any recomendations on places, or certifications would be good or are considered the "standard" would be helpful to me.  

So thoughts? #Project Manager #Salesforce Consultant #Salesforce
