Helen Hall

Helen is the founder of AVR and our Executive Chairman. Since starting the business in 2002 aged just 26, Helen has worked tirelessly to build AVR into the business it is today. With over 19 years of experience Helen continues to drive the company forwards, always ready to explore new technologies and solutions but never at the expense of client service.

At the end of March 2017, Helen started maternity leave, preparing for the birth of a much-wished-for little girl with her partner Ross and beautiful Isabella was safely delivered on 23rd April.

Helen appointed Sales Manager Nick Kellaway as Managing Director in her place.  She remains closely involved with AVR, advising, consulting, assisting with new business initiatives and helping to drive the business onto greater success.

Nick Kellaway

Nick joined AVR in 2014 from Integralis working alongside AVR founder Helen Hall. In 2015 he was promoted to Sales Manager and managed the sales team to great success for 2 years. In April 2017, Nick was promoted to Managing Director.

Nick has a passion to help AVR’s customers with their cyber security and mobility journeys. He also loves to see his AVR colleagues grow and evolve to be the best they can. Nick has a BA Honours degree in Classics and History from Keele University and a Diploma in Computer Applications. Father of two lovely kids, Josie and Luke, Nick is an enthusiastic football fan, whether playing himself, supporting his beloved if somewhat frustrating Spurs or living the game vicariously through his son.

Jo Wendland

Jo has 20 years’ experience as a recruitment specialist.  She’s worked in all kinds of environments from in-house roles for global enterprise organisations, to external roles in RPO, HR consultancy and tech start-up.  Her role at AVR covers all things people; from recruiting talent in to the team, to onboarding, HR practice and process, to training, development and coaching.  Jo brings to the team an instinctive love of people and a special interest in behavioural analysis.  Jo comes to work for a rest from her three young children.


Stephen Donovan

Stephen is responsible for the marketing and communications at AVR…or ‘colouring in’ as it’s affectionately called by his colleagues!  From his time ‘on the road’ as a sales representative then a senior sales manager, Stephen developed his love of marketing at the sharp end.  His broad marketing experience was honed with spells at large corporate organisations, SME’s and independent consultancies. Always eager to learn more and put his creative and writing skills to good use, Stephen enjoys the challenges and opportunities of blending traditional marketing techniques with the latest digital platforms and technology.  In his free time he loves spending time with his partner and family, watching sport, listening to soul music and keeping fit.  Travel is also a big passion with New York being a much-loved city, just behind his number one location – London!

Mary-Ann Politis

Mary-Ann, better known as Fred (but no-one knows why!), is AVR’s Sales Manager. Fred has been at AVR for over 5 years and has risen through the ranks from SMB sales exec to now running the busy AVR Sales Team. Her years of experience and knowledge of the solutions and people within IT Security is a great asset and she is loved by clients and colleagues alike, despite her cleanliness obsession and her unceasing cheeriness! She is  always bright and positive and definitely a ‘half glass full’ type of person – a perfect personality to have on the team.
