Growth Marketing Specialist

I create growth systems that scale.

From building marketing functions from the ground up, to scaling multi-channel acquisition engines, I help health and consumer brands grow faster, more efficiently, and more profitably.

What I do

Services

Fractional Growth Lead

Senior growth leadership embedded in your team, without the full-time hire. Strategy, execution, and accountability across the full funnel.

Strategy Consulting

Channel mix, budget allocation, and prioritisation built around your business, no one-size-fits-all recommendations.

Digital Audits

An honest, independent review of what's working, what's not, and where the biggest opportunities are hiding.

Performance Ads

Meta, Google, and beyond. I manage spend, build creative frameworks, and optimise toward real business outcomes.

Lifecycle & CRM

Email, SMS and in-app campaigns that keep customers engaged and reduce churn, especially when acquisition costs rise.

Conversion Rate Optimisation

Get more revenue from existing traffic. I audit the full funnel and run structured tests that compound over time.

Where I've worked

Experience

Healthscreen

Growth Lead

2025

Before me, there was no dedicated marketing function. I built it from scratch — strategy, tooling, creative processes, and performance infrastructure — then scaled it.

  • Built the marketing function from zero: strategy, tooling, and team processes
  • Scaled paid media spend across Meta and Google
  • Implemented a structured creative testing framework to improve output velocity and quality
  • Drove conversion rate improvements across the acquisition funnel

Eucalyptus

Growth Marketing Manager

2023–2024

Three distinct phases in two years — each requiring a fast pivot and a different playbook.

Started by scaling Juniper's GLP-1 program during peak demand. When supply constraints hit the market, I shifted to protecting revenue: building content and CRM programs that kept existing customers engaged. As conditions normalised, I rebuilt the acquisition engine and set the foundation for the next growth phase.

  • Scaled performance marketing for Juniper's GLP-1 program during high-demand phase
  • Built content and CRM retention programs to reduce churn through supply disruption
  • Rebuilt acquisition infrastructure ahead of market normalisation

Webprofits

Principal Consultant

2019–2023

Nearly four years across the full consulting lifecycle — from launching campaigns to owning strategy across a portfolio spanning e-commerce, health, finance, and SaaS.

  • Managed $500K+ in monthly ad spend across Meta, Google Ads, and YouTube, consistently delivering against client acquisition targets.
  • Drove a 300% increase in conversions for a key client through a full-funnel acquisition strategy rebuild — new campaign structure, landing pages, and email sequences.
  • Scaled a Google Grant program by 20%, navigating grant restrictions to unlock incremental reach for a non-profit client.
  • Built performance reporting frameworks that gave senior stakeholders clear visibility into spend efficiency and growth trajectory.
  • Led training and mentoring for all new associates and interns across campaign management and analytics.

About me

Senior operator thinking, not another agency retainer.

I'm a growth marketer who thrives on complex business challenges. Give me a blank slate and I'll build the system. Give me a broken funnel and I'll find the leak. Give me a market disruption and I'll adapt.

Over 8 years, I've operated in-house at some of Australia's most ambitious health and consumer brands and consulted for dozens more across e-commerce, SaaS, and finance.

I work with founders and marketing leaders who need someone who can think strategically and execute — not just one or the other.
