I’m Justin.

As a Strategist at Part and Sum, I help brands uncover insights and tackle complex problems by using data, creativity, and figure-it-out-itude 🚀

Over the past six years at Part and Sum, Justin has partnered with organizations ranging from global brands like Cengage, Life Time, and ASME to fast growing e-commerce businesses including Artemis, Piecework Puzzles, and Fox Fodder Farm. Regardless of company size or industry, his approach remains consistent: start by listening. By deeply understanding each client’s goals and challenges, Justin builds strategies that are both thoughtful and results driven.

One of Justin’s favorite parts of any engagement is facilitating workshops. He thrives on bringing teams together, fostering collaboration, and aligning stakeholders around a shared vision and clear path forward.

Among his proudest achievements is leading the paid media strategy and execution for The Nature Conservancy’s Earth Day 2022 campaign, which was named a finalist for The Drum Award for “Most Effective Use of Insights on Paid Media.”

Justin believes strong relationships are the foundation of meaningful work. Built on trust, transparency, and collaboration, those relationships create better outcomes, for clients and their teams alike.

“Seeing through the eyes of your customer is step one and serves as the foundation for all things strategy. Prioritizing the customer's needs and wants should guide every aspect of the business, from product development to marketing to customer service. By keeping the customer at the forefront of every decision, businesses can create lasting relationships and generate loyalty, resulting in long-term success.”
