Tanya Bricker

Sussex Equine Hospital

LMS Group have been providing my IT and telecoms support for almost one year now. I have found all members of the team to be friendly, helpful and knowledgeable.
The cost was so reasonable that I asked them to check if they had invoiced me correctly.

Jane Blaber

Liberty Bookkeeping

The new dedicated leased line has made a very positive impact on all we do here and the new phone system is also making us much more efficient.
In addition, I would like to praise the service LMS provide when we call for assistance for anything from computer queries to aiding in setting up Dropbox for business for us.
