Our Team


Working hand in hand with business owners and marketing teams to drive businesses forward, Aidan’s passion is creating marketing communications that enable Irish SMEs to achieve increased levels of growth and profitability.
Having worked with many of the best creative people in Ireland, it’s hardly surprising that cut through creativity is at the very core of the majority of project solutions he delivers.
As a committed and dedicated brand champion, Aidan advises on every aspect of the marketing process, from strategy and concept development through to implementation and subsequent evaluation.
In 2013 Aidan co-founded O’Connor & Kelly Ltd with Jim Kelly as a marketing-led business consultancy focused on supplying outsourced solutions to SME businesses and not-for-profit organisations.
Aidan holds a BA(Hons) in Business and Strategic Management from the Irish Management Institute, as well as diplomas in Digital Communications and Media from the Digital Marketing Institute and in Marketing from Dublin Institute of Technology.
As well as being a member of the Small Firms Association, Aidan has been a director of Unicef Ireland and chair of Nurture.


Christina Clarkin has a wealth of experience in the industry working with companies varying from solopreneurs to multinational firms, such as, Microsoft. This comprehensive mix of work experience has provided Christina with a deep understanding of commerce, big picture thinking and the tools for driving successful marketing campaigns.
In her own words - “I’m enthused by the ever-changing world of marketing and my experience in both digital and traditional media helps me to create campaigns and strategies that deliver measurable results for all my clients.”
When Christina is not in the MX3 office, she is leading the Network Ireland Wicklow branch as the 2022 President.
The Wicklow News is quoted as saying "Wicklow woman Christina Clarkin, who is the current President of the Network Ireland Wicklow branch, shares her experience of setting up her own business and the support the Network gave her." Read the full article here
