Katie is a Director at Marshall Diel & Myers Limited and has almost 20 years’ experience as a lawyer.  Prior to joining Marshall Diel & Myers Limited, Katie was a Solicitor in the Insurance and Reinsurance Litigation Group at Edwards Wildman LLP in London. She joined Marshall Diel & Myers Limited in 2008 and was appointed as a director in 2012. Katie is active in the development and supervision of MDM’s student and pupillage programs.


Katie’s practice encompasses all aspects of commercial litigation with a particular focus on complex, high value and cross-jurisdictional commercial disputes for clients in Bermuda and internationally and insurance and reinsurance disputes. Katie frequently works as part of an international team and works closely with King’s Counsel and instructing attorneys from major firms in England, Canada and United States. In particular she has acted in high value disputes relating to trusts, financial institutions, funds, professional negligence, the affairs of companies, their directors and shareholders, insolvencies, employment, personal injury and medical negligence. She frequently drafts and negotiates non-disclosure, confidentiality and settlement agreements. 

Katie also manages the insurance and reinsurance practice and has significant experience in handling large insurance coverage disputes in arbitration and, in particular, disputes concerning the Bermuda form. Katie also has extensive experience of arbitrations which have addressed various highly contentious London market issues for both solvent and insolvent reinsurance companies and has acted for clients in the live market and clients that are in run-off, including Lloyd’s corporate members.

Katie also regularly advises on commercial and regulatory matters and is regularly instructed to draft commercial agreements and business related documents in a manner that articulates the message which the client wishes to convey. In particular, Katie is legal counsel to one of the biggest oil and gas suppliers in Bermuda and is involved in drafting, reviewing and negotiating agreements for every aspect of their business and advising them in relation to legal issues that arise in the operation of their business.

Katie is extremely passionate about her work. She is not only able to grasp complex legal issues very easily but she understands what it means to deliver results for her client. She will always ensure that she understands her clients’ commercial objectives and their businesses to achieve the results that they want.
