First Person or Third Person

I am putting together my website for my business. The focus initially is for education/information sharing for health care providers in pain management and to serve as a home for my professional lecturing. My question is, should I write the info text in first person ie: have an “About me” section and write it in first person or is it better to have an “About Megan” section and write it in 3rd person. I am planning on having a blog as part of this (and maybe a podcast- of course) so those would obviously be in the first person. Does it seem more professional to have the website text be in third person? or is there no right answer and I can just pick? Thanks-
