“Mosaic Group is dedicated to delivering market access and reimbursement marketing solutions to our clients,” the agency leadership team states. “On the heels of COVID-19, improving patient access to medications is more important than ever before — for our clients and for the patients they serve. That’s why Mosaic has taken on the mission of patient access as our guiding light. The Mosaic mantra ‘Our People, Our Passion, Our Power’ underscores our team’s dedication to supporting optimal access to life-changing medications.”

Recent accomplishments

Mosaic achieved “unprecedented” success in 2021 and continued to thrive in the ever-growing and competitive world of market access in 2022, according to managers. 

With the growth of its business, came the growth of its team. After almost doubling in size in 2021, the Mosaic team grew an additional 20 percent in 2022. 

“As co-leads, Managing Directors Jill Lesiak and Anna Loyeva are committed to creating a culture of collaboration, creativity, and community, where team members come together to produce compelling market access tools and solutions,” managers say.  

In 2022, Mosaic delivered 11 successful market access launches for current clients and had seven new client wins representing products across multiple therapeutic categories. “The diversification of our client roster includes cardiometabolic, oncology, and rare disease,” executives say. 

In 2022, the agency added team members across all disciplines – account, copy, art, strategy, project management, and editorial. For a second year in a row, the agency grew its strategic bench by adding three new strategy team members. “A key addition to our team was strategy co-lead Reta Mourad, a former payer with real-world expertise that she applies to our clients’ challenges through her insightful strategies,” executives say. 

Managers say in 2022, Mosaic’s strategy team produced upwards of five thought leadership pieces. Late in the year the agency unveiled its new point of view series, “Eye on Market Access.” Mosaic also launched eight payer surveys on relevant, timely topics to gain and share real-world insights with clients. Topics explored included oncology, rare disease, biosimilars, and payer preferences on content consumption.

According to leaders, creativity and connectivity are core to the agency’s culture and among what makes Mosaic unique. “In 2022, Mosaic launched MASH – a Market Access Strategic Hackathon – bringing together Mosaic team members and IPG Health colleagues across varying disciplines to engage in rapid fire, collaborative ideation aimed at generating solutions to several market access industry challenges,” executives say. 

Additionally the agency strives to create an environment that promotes camaraderie and connectivity. “We established a new TEAMS channel called The Juice Bar,” executives say. “The Juice Bar is a place for team members to come together and share what inspires us from across the healthcare industry and beyond. Posts energize us, ignite virtual conversations, and feed our creative souls, germinating new ideas for our clients.” 

Mosaic is committed to the continued growth and development of its team and network colleagues, leaders say. “Our visionary training curriculum, called MAX (Market Access EXcellence) continued to expand in 2022 with the addition of several relevant and timely modules and live lunch and learn engagements.” To enhance the market access knowledge and acumen of IPG Health colleagues, Mosaic develops and co-hosts “Market Access 101” webinars. 

“It’s our people, our passion, and our power that led to Mosaic Group taking home the 2022 MM+M Awards’ inaugural Market Access Maven Gold award,” executives say. 

Structure and services

As a full-service market access agency, Mosaic is “passionate about optimizing patient access to important therapies so patients can live healthy and fulfilling lives,” executives say. “Our team is composed of specialists, many with advanced degrees in healthcare or real-world experience from the payer world. 

Mosaic’s primary practice falls into five key categories: market access strategy and communication planning; market access branding and creative; market shaping/disease awareness; value messaging and communications; and access and reimbursement support initiatives and pull-through communications. 

“Strategy is at the core of what we do for our clients and their brands,” the leadership team says. “Everything we create is grounded in insights and strategy ensuring that we develop on-point, compelling and relevant communication vehicles. Our propriety market access panel, which includes current healthcare decision makers from across a variety of customer types, enables us to tap into real-world perspectives and learnings that we apply to our everyday work. 

When it comes to its return-
to-office approach, Mosaic, like other IPG Health agencies, continues to lean into the network’s philosophy of flexibility, accountability, and trust. “Unlike other agencies and networks, we trust our employees to work with their teams to figure out what works best for themselves, their families and their clients,” executives say.

Future plans

Our mantra ‘Our People, Our Passion, Our Power’ is at the heart of everything we do,” the leadership team says. “Our people and our passion give us the power to create positive change in support of our clients and the patients they serve. For 2023, we plan to continue to strengthen and apply our strategic prowess. We will expand our strategic presence in the industry by delivering relevant and credible thought leadership pieces through POVs, conference engagements, and more.  

“We will also continue to ignite our creativity with our Juice Bar interactions and a Spring and Fall MASH Hackathon. We plan to develop new digital solutions that will address key market access marketing challenges. We also will continue to embrace and nurture team connectivity and community through engaging team experiences and activities that celebrate the accomplishments and unique perspectives of team members.” 


The Mosaic team is passionate about Equity, Diversity, and Inclusion (EDI) and many team members support their passion through their participation in [email protected] Health, our network’s employee-led EDI council. [email protected] Health supports various initiatives that celebrate the diversity of team members, their uniqueness, and their individual cultures. As a group, [email protected] Health unifies us collectively as we recognize and celebrate EDI across our network. In 2022, Mosaic launched a LinkedIn campaign, ‘Our Mosaic’ that celebrates team members’ unique talents.” 

Mosaic also continues to partner with Touro College of Pharmacy, serving as an Advanced Pharmacy Practice Experience preceptorship. “Our co-lead of strategy, Elizabeth Cobb, has served as the preceptor since our engagement began in 2017,” executives say. “In 2022, Mosaic hosted six sixth-year students providing them with a purview into the role of healthcare communications and market access strategy.”
