Ben Sinclair

Chief Financial Officer


Our industry is a minefield of legislation and contractual obligations which require comprehensive indemnity insurance. There was a real void in the insurance market for the type of coverage we needed.

Alexander Margolin of Sioma Insurance was able to broker a policy that met all our commercial and legal requirements at a competitive rate.

I cannot recommend Alexander highly enough for his professionalism, business acumen and depth of knowledge.
