Marketing built
on partnership.
We're a boutique agency rooted in Milwaukee and built for the long haul. Senior strategists who embed with your team, learn your business, and stay invested in your growth.
We help you grow
Jack Russell Marketing was founded by Cassie Skindzelewski, a senior marketing strategist with over a decade of experience helping brands grow with purpose. Cassie built this agency to be something different: a boutique team that works directly alongside you, brings real expertise to every engagement, and treats your brand like their own.
About Our Founder
Cassie Skindzelewski spent over a decade working across both ends of the business spectrum—fast-moving startups where resourcefulness and speed were everything, and enterprise organizations where scale and process demanded a different kind of thinking. Along the way, she built a reputation for doing marketing the right way: with strategy, with heart, and with a genuine investment in the people she works with.
The idea for Jack Russell Marketing came from an unlikely place. Cassie’s Jack Russell terrier, Kandy, has the kind of energy that’s hard to describe until you witness it firsthand. Bright, joyful, tenacious, always moving, impossible to ignore. Watching Kandy one day, Cassie recognized something familiar. That was what great marketing felt like when it was working. Full of life, impossible to ignore, and always moving forward. So she built the agency around that spirit.
Jack Russell Marketing was founded on a simple belief: that businesses deserve more than a vendor. They deserve a dedicated partner who embeds with their team, learns their brand, and stays invested in their growth for the long haul. Marketers who treat your brand like it’s their own.
Today, Jack Russell Marketing serves clients across the country and around the world from its home base in Milwaukee, Wisconsin. The team works across three core areas—Brand and Creative, Digital Marketing and Content, and Strategy and Operations—delivering the kind of senior-level thinking and care.
Milwaukee is home. Growth is the mission. And yes, Kandy is still full of energy and continues to be the heart of Jack Russell Marketing.
