First let me appologize if this comes through as Anonymous which I'm getting a notice that it will but the login isn't working - this is Dave Davies, one of the owners.
We've worked with an array of different company categories from independent doctors to major companies. The issue it generally more related to the cause of the reputation management problem than the sector though a good question as certain sectors are faster to move it.
I understand that you probably don't want to give details here. You're welcome to email me at [email protected]
and I can give you my thoughts about what your specific scenario would entail.
