“Outside of spending time with family and friends, I follow a few sports and try to keep up with them as much as possible. Football will always be first on that list – Spurs! But I try my best to keep up with the goings on, and catch a game when I can, of Rugby Union with London Irish and the NFL with the Eagles. Other than that I’m probably writing, drawing, painting, or gaming.”

Marketing Manager

Adrian joined 42T as Marketing Manager towards the end of 2020. He has worked in marketing for almost 20 years’ and has experience of developing and building brands, creating and implementing integrated marketing plans incorporating a mix of digital and offline marketing. His background is mainly in financial services and has spent the majority of his working life in London. Adrian has a CIM Professional Diploma in Marketing.

“Joining an engineering consultancy near Cambridge wasn’t exactly an obvious next step for me, living as I do in Berkshire with a track record in financial services. But when the opportunity arose I jumped at it. The people and culture of a business has always been important to me, and it’s clear there’s something special about 42T. Everyone is so friendly and supportive of each other, and it’s an incredibly talented team. 

Outside of work I try to keep some semblance of fitness; playing squash and table tennis, cycling and taking our Cocker Spaniel for long walks in the Berkshire countryside. In reality, knee surgery (after a fight with a surf board) means I now saunter around the squash court hardly breaking a sweat; and our lazy/stubborn dog means I spend more time standing on a walk than I do walking. But it’s still time away from the screen and in the fresh air.”

This amply demonstrates the breadth of the projects 42T handles. It’s impossible to predict what will come through the door next! The projects I’ve personally been involved with have presented significant challenges so giving me the opportunity to expand my knowledge in many areas. It‘s tremendously satisfying to be part of a fantastic team working on projects that are literally industrial in scale as well as smaller, niche projects having the potential to improve the health and life of people the world over.

“Shepherding our disparate band of six strong willed individuals along the path to their futures is a significant undertaking outside work, but is also a great excuse for exploring the world around us and not necessarily acting your age. Fortunately they all seem to love old aircraft, old cars and the countryside.”
