Marina Maher Communications Names Olga Fleming Global President of MMC and RXMOSAIC

by | Apr 13, 2022

Marina Maher Communications (MMC) announced the appointment of Olga Fleming to global president of MMC and specialist agency RXMOSAIC, effective immediately. Fleming is now responsible for employee engagement, client business and driving growth across both agencies. She reports to MMC founder and global CEO Marina Maher.

Fleming has close to three decades of experience leading people and agencies in healthcare, consumer and corporate communications, and helping clients navigate complex and competitive environments to establish brands and build corporate equity. She launched the first immunotherapy ever marketed and is regularly called upon to develop thought leadership platforms for Fortune 500 companies. Fleming also founded and was CEO of Goodfuse, a boutique communications agency within WPP.

“Olga is the perfect choice for this role,” observed Maher. “She is both a visionary leader and an accomplished hands-on practitioner with deep experience in healthcare, corporate and consumer. She is a savvy businessperson with an entrepreneurial spirit that’s on full display when one looks at her track record of building business and driving growth. And she does it all in a way that builds excitement and trust with employees and clients alike.”

“MMC’s secret sauce for success has always been its culture and its people,” said Fleming. “And I am excited to partner with Marina and other leaders across both agencies to build the MMC of the future – one that is home to the best and brightest people in the industry who know they are supported and empowered to creatively connect brands to culture and deliver outsized results for clients.”

Fleming takes on her new role as Rema Vasan departs for a leadership opportunity in the digital and tech innovation sector.

Maher added, “I have always been passionate about seeing women thrive in their careers and succeed in leadership roles. It is the foundation upon which MMC was built. So not only am I excited about Olga, I am also delighted for Rema and absolutely confident that she will thrive in her new role, which plays to her ingenuity and commitment to constant innovation.”

Contemporaneous with Fleming’s appointment, Ivette Sanz Osso is promoted to chief client experience officer, a newly created position leading MMC’s Client Delivery Excellence team, which ensures clients remain at the heart of all the agency does. Sanz Osso now reports to Fleming and they will partner closely to ensure MMC continues to deliver a level of excellence for clients that is ahead of the industry curve.

In her new role Sanz Osso will apply her expertise in client partnership and team design to reimagine service models, team composition and ways of working to deliver next level business results to clients.

“I’m fueled by working with teams to look beyond and think differently about how they collaborate with clients to create a winning experience; you can say that that I’m a passionate change communications specialist,” said Sanz Osso. “And I can’t wait to partner with Olga to set a new standard for what an agency-client relationship can deliver.”
