Who Sam Works With

Sam works with a variety of corporate clients, individuals, insolvency practitioners and other professionals. His clients include professional service firms, property developers, contractors, subcontractors and a range of SME’s.


I solve problems and help business owners to avoid them in the future.

I firmly believe that a Lawyer’s role is to help people identify causes of potential problems before they arise, not just to find the best solution once a problem has manifested.

I have an excellent track record for resolving large disputes by negotiation and avoiding drawn-out and expensive litigation. This is because I take the time to fully evaluate the strengths and weaknesses of a client’s claim from the outset and draft detailed initial letters of demand that typically result in early settlement negotiations.
