Hi, I’m Leslie.
I built Doug The Pug into one of the most recognized pet brands in the world, growing a social audience of over 18 million followers and expanding it into a multi-platform, multi-revenue business spanning bestselling books, major brand partnerships, global media coverage, and live events.
That hands-on experience shapes the work I do today. I help brands and organizations turn attention into lasting visibility by building social strategies and creative direction that are culturally relevant, audience-first, and designed to drive real business outcomes.
I work at the strategic level — developing direction, systems, and creative frameworks that scale — while staying deeply connected to what actually performs on each platform. With over 12 years of experience, my work spans consumer brands, media companies, nonprofits, universities, and established creators, with success measured in sustained visibility, meaningful growth, and impact beyond vanity metrics.
"Leslie Mosier is a brand equity and revenue multiplier. Her ability to navigate social media through deep audience connections, organizational alignment, and integrity is exceptional, driving visibility, engagement, and sustainable growth for any client.

In just four months, our Instagram has gained over 30,000 new followers and seen 2.3 million views in the past 120 days, connecting us with a whole new audience. Leslie truly is the engine that keeps our small but mighty social media team running, and her impact is undeniable. I highly recommend her!”
Jeanne Rebillard, Director @ Endometriosis Foundation of America
MY APPROACH
-
IDENTITY
I start by looking closely at what you’ve already built — your channels, your voice, and what’s resonating with your audience. From there, we clarify what your brand stands for and how it should show up consistently across platforms.
Whether that means refining what’s already working or reimagining how your brand shows up entirely, the goal is the same: to create an identity that’s clear, recognizable, and instantly engaging — so people understand who you are and why you matter the moment they find you.
-
STRATEGIZE
Once that foundation is clear, I shape a social media strategy that gives your content direction and purpose. We define what belongs on each platform, how your ideas translate into content, and how everything works together instead of feeling scattered.
Social media is always changing, and I build strategies that can adapt in real time — so your presence stays relevant, intentional, and effective as platforms and culture shift.
-
GROW
Growth happens when content feels aligned, consistent, and genuinely engaging over time. As strategy is applied, visibility builds naturally — opening the door to deeper audience connection, stronger brand recognition, and new opportunities.
I focus on growth that actually matters: sustained visibility, audience momentum, and outcomes that extend beyond social media into real business impact.
