Team Emerald

Darren Windrum - Co-Founder

Darren founded Emerald with Sarah in 2009 after working in both the public and private sectors for 6 years. He has a BSc in IT Management and is a PRINCE2 Practitioner. He has always enjoyed solving problems from his childhood on the dairy farm in Ireland!

Darren believes strongly in being honest and ethical in all things and is a man of real family values. He also loves meeting people and will happily tell you witty stories and anecdotes all day long. That's the Irish genes we think!


Sarah Windrum - Co-Founder

Before Emerald, Sarah worked for a London based mobile technology group leading on new mobile implementation for the public & private sector.

She has a MA in English Literature and a Postgraduate Award in Strategic Leadership and Change Management although her steepest learning curve has been leading a rapidly growing business with Darren since 2012.

Sarah has a daughter Keva and is a part-time poet and novelist.


Simon Wilks - Technical Director

Simon has been working in the IT industry since 1994. He has a wealth of experience in how technology operates across many different sectors from financial services in Canary Wharf to business start-ups in Leamington. 

Simon is a competitive triathlete and ran the London Marathon for British Blind Sport, one of our charity customers, in 2012. He regularly raises money for them and other charities through his competitions.


Hannah Wiltshire - Mobile Operations Manager

Hannah began her career in hairdressing at 16 years old and made the transition to technology in 2013 starting her Emerald experience in the mobile processing team. She will admit it was a steep learning curve but a difficult step definitely worth taking!

Hannah has two beautiful children and uses technology to fit her work around her family. She is based primarily in our satellite site on the South Coast near Portsmouth.

Hannah loves to push herself to the next challenge and recently raised over £600 for The Meningitis Trust by going from Couch to 10k! She's fast-tracked her Emerald career too and is now our Mobile Operations Manager taking care of our mobile workforce customers.


June Reynolds - Technical Support Engineer

June has always been passionate about hands-on technology and was thrilled to turn her love into a career following a switch from retail management to joining the Technical Support team at Emerald in 2014.

June works hard to be a role model for her gorgeous little boy (and so many more!) She's Apple Accredited & studying for more exams. June takes hold of a query and will not rest until it is reolved. Tenacity is her middle name!


Laura Summerfield - Finance Manager

Laura is the backbone of Emerald keeping cash flowing through the business! She'll be the person you speak to about your invoice queries and is responsible for ensuring all our suppliers are paid promptly too. You never know when we might need a favour so keeping all relationships healthy in our Emerald eco-system is crucial. Her background in finance is from the public sector so she's a stickler for the detail! She's studying to be a Chartered Accountant through her AATs and Robert Wood's support.

Laura has two children Chloe-Louise and Kian and is a very proud mum and wife. She's also the backbone of her extended family and her sisters Hannah and Sarah wouldn't function without her!




John Differ - Technical Support Engineer

John came to us for work experience while he was re-training as an Network Engineer at Warwickshire College. We were so delighted with his determination and can-do attitude that we offered him a full-time position after he graduated in 2016. Since then he has gone from strength to strength and is now our road warrior out in the field supporting customers with those difficult issues that cannot be solved with remote support. 

He's supplemented his Foundation Degree in Network Engineering with the current Microsoft Office 365 accreditation and technical certification with all our infrastructure partners. His background in retail means he is always focused on customer service and our clients love his attitude and work ethic.





Kyle Boland - Technical Support Apprentice

Kyle started with Emerald in 2018 on an IT Technican Apprenticeship. He is now a Microsoft Technology Associate and we are excited about supporting him on his journey to Hardware Specialist. He has quickly become an integral part of the team and we are thrilled with his progress.

Kyle has a little boy called Toby and his favourite job at Emerald is choosing the music we listen to everyday in the office!





Robert Wood - Finance Director

Robert has worked with Emerald for many years both as a customer and as an interim Finance Director since 2015. He has supported Sarah and Darren immensely during a period of great stress and continues to do so in order to take Emerald to the next level. He is a Chartered and Management Accountant with a wealth of experience in the corporate sector and with small growing businesses since he started his own practice.

Sherine Reynolds - Mobile Billing Administrator

Sherine works part-time with us while taking care of her young family. If you are a mobile customer, you will receive your bill each month from Sherine. She works closely with Hannah to ensure we keep control of mobile costs on a monthly basis.
