Publicis Health Media

Philadelphia has 137 advertising agencies in this category, too many to scroll through one by one. Zip code narrows it fast. Center City zips 19103 and 19106 each carry 15 agencies, 19107 has 14, and 19102 has 9, so if you know which part of Philadelphia you want, start there. Most entries include usable contact info: 135 listings have a phone number and 127 have a website, so you can check a site before calling.

None of these listings are marked verified, and this category has no paid placements in Philadelphia yet, so any future sponsored spot would carry a Sponsored label instead of blending in. If you run one of these agencies and your phone or website field is blank, you can claim the listing and fill it in, since an incomplete entry is easy for a prospective client to skip past. From there, pull a few agencies in your target zip code and call two or three before deciding who to brief.
