Fractional CMO | Growth and Performance Marketer

With over 25 years across sales and marketing, I work as a Fractional CMO for business owners who want growth without guesswork.

I step in when marketing feels busy but results feel uncertain. Spend increases. Systems sprawl. Sales and marketing drift apart. I take ownership and bring structure back to growth.

My background combines in person sales leadership with deep hands on experience across paid search, paid social, programmatic, and ABM. I look at growth as a system. Strategy, channels, tracking, and decision making either work together or performance breaks down.

I stay close to execution when needed. Not to run tasks, but to fix performance, guide teams, and make better decisions faster.

What I do.

• Fractional CMO leadership for owner led businesses

• Growth strategy aligned to revenue and sales goals

• Paid media oversight across Google, Meta, LinkedIn, and programmatic

• Media planning, budgeting, and forecasting

• GA and GTM tracking and reporting

• Team direction and performance accountability

Where I have delivered results.

• Managed over £500 million in ad spend

• Improved conversion rates across ecommerce and B2B

• Reduced acquisition costs while increasing ROI

• Led complex campaigns in regulated sectors including healthcare

Why work with me.

You get senior ownership without complexity. I focus on clarity, accountability, and outcomes. I build systems your business can trust, not campaigns that rely on constant intervention.

How we work.

Most engagements run as a monthly retainer. For the right partnership, performance incentives align outcomes and priorities.

If you want marketing leadership that treats growth like a business function, not a channel mix, let’s talk.
