Personally, I would not use anyone else.
To be honest, I keep Chip on “Speed Dial” for Digital Marketing counsel. He's consistently on top of any recent developments, and also, just as important is that Chip's solutions are both sound and simplified down-to-earth strategic recommendations that I can quickly implement for myself or my clients. Quick response. Very highly recommended, I recommend him to all my clients. Personally, I would not use anyone else.
