About Aidan Tollefson

I am a Senior Media Buyer with 5 years in the media trade industry, specializing in creative advertising strategies and data driven decision-making. I have experience managing multi-million dollar budgets, having planned, negotiated, and placed over $100M across channels and clients. Whether pharma, tech, retail or QSR, I am adept at navigating the unique challenges across industries and delivering results that drive ROAS and produce real results. I began my time at Evergreen on the local team, where I worked primarily on TV and audio: collecting logs, managing makegoods, and chasing down ADUs. However, as the company began to expand, I found myself at the forefront of Evergreen\'s streaming audio initiative. I was able to spearhead and found a new department, building processes from the ground up and becoming a subject matter expert on all things streaming audio. Since creating the streaming audio initiative, the business has grown exponentially as a direct result of the research, data analyses, and time I devoted. Today, I am a go-to resource for colleagues, vendors, and clients alike; I frequently lead discussions and make informed recommendations on how to optimize campaigns across channels. I had to adapt, jump into the unknown, and deliver a quality product that was entirely self-driven. Today, I work under the Integrated Investment team, where I work on channels including audio, national linear, and digital both directly and programmatically. I am passionate about cross-functional collaboration and am always happy to help; no matter the timeline, I will jump in and get the job done. I am always looking to expand my network and am excited by any opportunity to grow. Let\'s connect!
