An anti-agency collective of former in-house brand leaders, strategists, and operators who cut through the noise to help companies clarify their vision, take meaningful action, and scale with purpose.
Most agencies drop off a strategy deck and call it a day. We don’t. As former in-house marketing leaders, we know the gap between strategy and execution—and we built this consultancy to close it. Every engagement is bespoke, with a handpicked team of senior experts across growth, content, creative, PR, SEO, and thought leadership.
We don’t just advise; we embed, execute, and drive real-world impact—without the agency fluff.
About.
Three Lines Consulting is a creative consultancy that focuses on building, scaling and modernizing customer touch-points for bold companies while developing marketing leaders committed to positive growth. Founded by Molly McDermott Walsh, a change-maker and thoughtful risk-taker, Molly is motivated to make a difference in the world, helping good people do good things. With a focus on what she calls “the 4Ps” (people, purpose, product and profit), Molly aims for alignment and impact, guiding companies through change while owning, tracking and implementing process and accountability.
We work in three ways: A project-based strategy with a workshop handoff, a three-month retainer to guide and collaborate with your team, or a six-month+ engagement where we bring in top external talent to manage execution alongside internal resources.

reviews and real talk.
“Molly has a rare gift for distilling complex brand stories into clear, compelling narratives that resonate both internally and externally. Through a thoughtful and highly collaborative process, she helped us uncover and articulate the essence of who we are—not just as a company, but as a culture.
Her approach is strategic yet deeply human, balancing the voice of the business with the heart of the people behind it.”
Kirsten Darrow, CMO
“Molly has the rare ability to listen closely to founders and executives talk about their vision and plans, collaborate and create with them, and then distill their big ideas into actionable steps, producing practical execution of lofty dreams.
She creates the conditions under which progress happens. Molly's work was critical in making sure Chamber of Mothers grew from a scrappy group of idealists gathering together, into a sturdy advocacy organization that will stand the test of time.”
Erin Spahn Erenberg, Co-Founder & CEO Chamber of Mothers
“In a time where brands need to stand out in a sea of other brands, every company needs an expert communicator and champion, like Molly”
Dani Kennedy, creative leader
“Molly has a unique ability to identify opportunities that will elevate a brand or help it enter into new and unexpected spaces, championing creative ideas that at times require unconventional thinking, and doing.”
Monique Krasniqi, global communications leader
