Who's who at Gatwick Diamond Business:




Jeff Alexander 
Chief Executive 


I was delighted to become Chief Executive of Gatwick Diamond Business in October 2018. My background is in economic development and business support, and I have worked extensively in the Gatwick Diamond which has also been my home for over 30 years. 

I lead a professional and committed team dedicated to providing the support and services our members value to help sustain and grow their businesses.

I work closely with our Executive Council, chaired by Anya Ledwith, comprising experienced business people who help identify and champion the needs of our members and provide guidance to me and my team to ensure that we deliver the best possible service to members.

I look forward to getting to know our members, prospective members and partners over the coming months.

Katie Lines 

Marketing & Admin Assistant





Since starting as the new Business Administration Apprentice for gdb in July 2019, I have loved being part of such a great team. I enjoyed meeting some of the gdb members at the gdb Charity Challenge 2019 and of course at our many networking meetings, and I am excited for the future events that gdb have planned!

My role involves supporting the smooth running of the office and assisting with the delivery of the membership programme alongside the Membership Executive.  Some of my tasks include making outgoing calls to gdb members and non-members, keeping the database up to date, and working alongside the Events Executive with social media plans.

I am eager to bring the skills I have to the team and am ready for the challenge of learning new skills and new processes.  I am really looking forward to meeting and working with all the gdb members over the coming months.
