About me

A seasoned marketing leader with three decades of strategic and operational experience across the full marketing mix; spanning B2B and B2C, public and private sectors, in both client and agency environments. I have garnered experience within diverse cultures and industries; from Construction and Financial services to Energy and Technology- always focused on helping companies evolve, connect with customers, and grow with purpose. I strive to bring together everything I have learned, using senior-level experience and a consultancy mindset to help businesses grow with purpose, clarity and measurable impact.

Holding senior leadership roles across large and small SME companies undergoing significant change; from redefining the brand and customer strategy at the Construction Industry Training Board (CITB) to driving commercial growth and digital transformation at Nationwide Platforms (Loxam). I have helped reshape small to large marketing functions, lead brand launches and rebrands, and embed customer-centric cultures at organisations including Xoserve (Correla), Unity Trust Bank and Powershop UK, where I was part of the original start-up team launching a challenger energy brand as a sub-brand to nPower. Earlier in my career, I held senior marketing positions with Staysure Group, Barratt plc, Santander UK, and Lloyds TSB, developing a strong foundation in brand, data, and customer insight. Across every role, the common thread has been a commitment to helping organisations find their voice, building teams that believe in what they do, crafting strategies that truly deliver, and creating brands that connect with people in meaningful, lasting ways.

I firmly believe that marketing is most powerful when it’s authentic, human and aligned to the ambitions of the business and the people behind it.  I have built a reputation for building relationships that last, leading teams that thrive and bringing infectious enthusiasm to every challenge. I relish a challenge and thrive on pushing boundaries to stretch thinking, inspire creativity and drive meaningful change. Whether leading transformation, redefining brand strategy, or embedding customer-centric cultures, I combine commercial clarity with a pragmatic, can-do attitude. 

Fun facts

Fact 1:
Frequently found on a yoga mat, spin bike, or a long countryside walk — usually rewarded with a well-earned glass of wine and a chocolate bar (purely for energy balance, of course). I’m also a devoted recreational skier with a lifelong passion of the mountains. The crisper the snow, the happier I am !.

Fact 2:
A self-confessed interior design enthusiast, always looking for the next house renovation to part project manage, part creative direct. My infectious energy, sharp eye for detail and a keen tendency often leads to burning the midnight oil sketching floor plans and interior design ideas.
