Marketing Phd with no MBA?

[phdconfessional]

I graduated Summa Cum Laude from Western Kentucky University with a 3.8 GPA. I also graduated from the Honors College, which entailed completing a thesis project. My major was Corporate Communication with a minor in Marketing. I have 3 years full time marketing experience since I graduated. I am wanting to pursue my Phd in Marketing. I have yet to take my GMAT yet. How likely am I to get into a Phd program without having an MBA? Or is it almost necessary to get my MBA first? Will I be prepared enough to enter into a Phd program? Any advice would be appreciated
