Meet the team


I am Marcus Rennick and I lead both the Estates and Private Clients teams, which I have built with some of the foremost experts in the market. I’m an FCII qualified insurance professional and my insurance career has spanned over 40 years, mainly as a broker but I started my career as an Underwriter. In the last 16 years I have focused on high and ultra-high net worth private client business, as well as landed estates and rural enterprises.

My insurance interests include historic houses and art collections. I am also a member of a high and ultra-high net worth advisory board, and specialist group, which examine the needs of very wealthy private clients with the intention of developing smarter strategies to protect their assets. I am also a contributor of insurance press reviews.

Outside of work my personal hobbies include: architecture, mountain biking, motorsport, jazz and fine wines.

I am Nina Nash and I have recently been recruited to head the Private Clients team within the James Hallam Estates & Private Clients Division.  I am Cert CII qualified and previously worked for another Independent broker for 23 years managing their Private Clients team in Berkhamsted. My particular focus and responsibility is ensuring that existing and new clients receive impeccable service and support.

Whilst I have dealt with most types of Home Insurance, my particular areas of expertise include Fine Art, Jewellery, Contract Works for homes undergoing renovations as well as properties which have previously suffered from Subsidence. I enjoy nothing more than for my team and I to exceed client service expectations. In this regard, I am lucky enough to work with some very experienced and talented colleagues. We are all passionate about what we do.

Outside work I am a mother to Isabelle 13 and Olivia 12.  Their endless activities and social lives take up much of my time outside work; however I am a keen dancer and attend Ballet and Contemporary Street Dance classes each week.  In addition, I love food and cookery, music and travelling.

“I’m Lauren King, a Senior Account Executive, and I have been a part of the James Hallam Private Clients Division since 2009. I am a Cert CII qualified insurance professional with 20 years of experience within the Private Clients insurance industry.

I am a driven individual and I aspire to provide each of my clients with an exceptional service and product suitable for their individual needs. Insurance doesn’t have to be a “one size fits all” purchase and I enjoy getting to know my clients and their lifestyles, ensuring they have a policy that will respond accordingly should they ever need it.

My particular areas of expertise include high net worth individuals with private homes, secondary residences, fine art, jewellery, classic motor vehicles and high value everyday vehicles.

Away from the office I am a family orientated person, I regularly attend football games as various family members aged from 14 to 40 play for fun, and I like to travel and try new restaurants.”
