Why We Started

Will Dufresne, a proud San Diego State University graduate, started ESi Agency after discovering his passion for marketing. During his time at SDSU, he realized how many businesses struggled with poor digital strategies. He noticed a major gap in the market: businesses didn’t just need basic marketing services—they needed a complete, results-driven approach that aligned with their growth goals.

Through his work with both local and national brands, Will identified common pain points that held businesses back:

  • Businesses struggled to generate high-quality leads and connect with the right audience.
  • Companies needed user-friendly, optimized websites that turned visitors into customers.
  • Many wasted time and resources on manual processes that automation could easily handle.
  • Brands struggled to manage their online reputation and respond effectively to customer feedback.

Considering these challenges, ESi Agency was created to provide complete solutions. We help improve brands, simplify operations, and promote measurable growth.
