I've heard so many reasons why practitioners such as yourself are not actively on the internet, or why they don't have time for it.
I think they are actually smokescreens - inaccurate, avoidant, and understandable reasons people don't leverage the internet for themselves. Kind of like hiding your head in the sand.
97% of all consumers now search online for services and products near where they live, including finding healthcare practices such as yours. They read online reviews too.
If people can't find you, and if you don't have a presence, potential clients WILL find other more active and findable providers.
Why doctors should take the good with the bad in patient reviews. In patient feedback online, the best defense is a good offense. Rating of doctors is now part of the social dialog, and doctors can join in and have a voice.
