About Me

I'm a Performance Marketing Manager with 10+ years of experience in paid search and paid social. I manage large-scale Google Ads and Microsoft Ads accounts, spending over $100,000 per day, alongside Meta Ads, LinkedIn Ads, and other PPC platforms, working with any bidding logic or campaign structure the account requires. My focus is lead generation: turning "we just need more leads" into a predictable, forecastable pipeline.

I'm AI-native: I build AI agents that help manage accounts, automate data pipelines, and speed up analytics and reporting.

How I Work

Start with the goal, not the tactic

I focus on the number that actually matters, usually lowering cost per action and scaling conversion volume at the same time, not one at the expense of the other.

Fix the foundation first

Before touching bids or creative, I make sure tracking and data are accurate. Every scaling decision after that is only as good as the data it's built on.

Then experiment relentlessly

Once the foundation is solid, I test across every layer of the account, including bidding strategy, audience signals, ad copy, and landing pages, to find what actually moves the number.

LinkedIn recommendation, November 2024

I had the chance to work with Sienna on several projects in the behavioral healthcare space. She has strong experience with Paid Search, lead generation, and campaign management across Google and Bing Ads, including large daily budgets over $100K. What I liked about working with her was that she always focused not just on traffic, but on lead quality and overall business goals. She understands healthcare marketing well, works great with the team, and is very organized and professional in her work. Sienna is very experienced in PPC and digital marketing, and I'd definitely recommend her to any company looking for a strong paid search specialist.
