I built my career working with top-tier marketing technology companies like WordStream (then the #1 Google Premier Partner), HubSpot, and Boston.com—and for the last 5 years, I've been running my own freelance marketing consultancy.

Across the hundreds of accounts and thousands of campaigns I’ve managed or advised on, I’ve consistently delivered results for clients in industries ranging from health and wellness to SaaS, retail, and professional services. Clients love working with me because I’m a strategic thinker who’s hands-on, proactive, and obsessed with results.

With a B.A. in Graphic Design from Providence College, and a UX Certificate from General Assembly, I make sure your ads don’t just convert—they’ll look great and be backed by user-centered strategy. Whether you’re just getting started or looking to improve results from an existing campaign, I’ll bring clarity, strategy, and action to your digital marketing efforts.

ACCL CHICAGO CLIENT TESTIMONIAL

"We have the pleasure of working with Justine, a talented Google Ads manager, and we are very happy to recommend her to others. From the moment we started our collaboration, it was evident that she was dedicated to helping our business succeed.

Her level of knowledge and understanding of the intricacies of Google Ads really impressed us after years of trying to figure it out ourselves. She was able to craft highly effective and targeted ad campaigns that not only increased our online visibility but also brought in a significant boost in qualified leads and conversions.

We also appreciated how she took the time to learn our business (a small psychotherapy practice) so that she knew how to manage the keywords and ads to be most effective.

Moreover, communication with Justine was always great. She gets back to us in a timely manner and scheduling our meetings with her is always very easy.

We wholeheartedly recommend Justine to any business seeking to elevate their online presence through Google Ads."
