Renee Hill Young

We are proud to be the largest WBENC-certified, woman-owned agency in the country. Diversity has always been at our core, ensuring our agency and our work are reflective of the world we live in. This directly translates into greater success for our clients.

Gerald Bagg

Co-Founder

Founded in 2002 at the dawn of the digital age, Quigley-Simpson emerged with a wealth of performance-based marketing skills. Our name harkened back to the "Mad Men" era, evoking a vintage brand with its own rich memories. Over time, Quigley-Simpson became synonymous with strategic partnerships, transforming from a small agency into a leading choice for major brands. Our legacy celebrates a distinguished past adapted for the modern era.

Carl Fremont

CEO

I have always been a hands-on leader influencing the industry direction for brand safety, transparency, accountability, and diversity. My proudest moments are inspiring and leading companies and people to the future from past lessons I learned.

Kathryn Browne

CFO

I am proud to be a part of a diverse, WBENC-certified company that is dedicated to excellent corporate stewardship, transparency, and accountability.

Dalton Mangin

CRO

My passion is for developing comprehensive approaches to driving revenue. The clients I have worked with over the years see me as a partner that is vested and passionate, which aligns well with Quigley-Simpson’s impact obsession.

Mark Piazza

COO

I believe a company’s #1 asset is its people! My superpower is being a strategic business partner with each practice leader to help nurture growth in order to achieve our maximum potential.

Alissa Stakgold

President, Strategy & Creative Services

I’ve got a knack for turning business goals into actionable, strategic plans, making sure that every piece of work doesn't just hit the mark—it nails it. For me, it’s all about quality. Great work starts with real, spark-your-imagination insights that get people moving.

Jeff Ratner

President, Media & Analytics

“How do I do it better?” Those are the words echoing in my head when I log in each morning. I am constantly thinking about how we can use new tools, more nimble and empowered talent, and my media and marketing experience to create business growth for our clients.

Sariah Dorbin

EVP, Executive Creative Director

My superpower is developing the work of my phenomenal team while prioritizing impact. That means challenging everything. Is it fresh? Is it clear? Will it spark action? But my greatest joy is nurturing natural gifts and developing new strengths in our people.

Kelly P. Green

EVP, Account Service & Marketing

I enjoy looking at business through my clients’ eyes, while at the same time bringing them fresh and effective solutions that allow them to grow. As an agency, we’re connected to our clients’ businesses, but are also free to look at things from a different perspective.

Eric Koehler

EVP, Research & Strategy

In the pursuit of learning more about what motivates audiences, I love uncovering new information and seeing the previously unseen. People continue to always surprise marketers—and finding new insights to leverage to engage them is a never-ending opportunity.

Sie Ung

SVP, Media Investment

I am constantly looking at how we can approach media differently because it’s not “one-size-fits-all”. Business goals drive success, and I look to foster that growth in the media we execute and the relationships we build with all our partners.

Michele Boersma

VP, Talent & Culture

I have a genuine love for motivating, teaching, and supporting others and I am a dedicated leader focused on helping everyone perform at their peak and achieve outstanding results. I am committed to making dreams a reality and inspiring others to reach their full potential.

Nicole Ellingson

VP, Group Creative Director

I live and breathe creativity and strategic problem-solving—I thrive on it! I love uncovering insights that lead to work that works hard. My background in design and storytelling ensures our work is inspiring and beautiful, too.

Andrew Hiscocks

VP, Finance

I find enjoyment in the exactness of numbers, aligning each calculation like the pieces of puzzle. I am constantly thinking about how to optimize financial performance and implement effective risk management strategies to ensure organizational success.

Katrina Moore-Weiss

VP, Strategy & Planning

I bring my multi-faceted experience from media and integrated agencies, brand-side and small business ownership to achieve strong results and continued learnings. Strategy is always on the forefront. I am most proud of my entrepreneurial spirit and carry it with me daily.

Ashley Smith

VP, Strategy & Planning

As a seasoned professional in media, marketing, and communications, I specialize in crafting strategic cross-channel plans. My priority is driving measurable results, boosting brand visibility, and increasing sales through integrated cross-channel campaigns.

Jerry Sommerville

VP, Activation

As the activation team, we take your business objectives and translate them into fitting audiences, creative, levers, and algorithms across platforms. As the head of activation, I have the daily privilege of seeing your goals realized through the work of savvy platform experts.

Carol Jenss

VP, Strategy & Planning

I treat my client’s businesses as if they were my own and I look to continually find ways to improve performance and drive results. Equally important to me is nurturing relationships and being a true partner.

Jared Vail

VP, Data & Analytics

I help drive the analytics practice across Quigley Simpson. I have worked in the advertising and technology space for the last 13 years on major brands. I am most proud of having the opportunity to develop and build future leaders in the analytics space.
