Executive Assistant

I have a marketing agency and I need someone to help me with the following:
- Respond to emails, and text and facebook messages - these are all about work
- Take client's and lead's birthday details off of Facebook and ---------- and saving them to Keap (keap.app/)
- Remind me of important stuff
- Communicate with the whole team when needed (Designers, Project Managers, Video Editors, Writers, Web developers, other vendors)

You should be:
- Organized
- Proactive
- Self-starter
- Problem-solver
- You should have no problem communicating with everyone
- Knowledge about marketing is a plus
