Great marketing starts with a deep understanding of the target audience and delivers messaging to meet their needs.

Marlene leads Celtic by defining a culture of integrity and creating strong relationships with client marketing teams.


She is passionate about using data to create a defined marketing strategy. Through experience and industry knowledge, Celtic focuses on delivering campaigns that speak to target audiences and drive ROI.

Q: Is there a specific motto you lead by?

A: Drive new ideas by asking “what's next.”

Q: What is one document you always keep on your desk?
A: The company org chart. In managing our people and agency processes, I want everyone to know their role. The org chart keeps me focused on where we are while I plan where we’re going.

Q: How do you finish your workday?
A: I create a list of firsts for the following day and leave it on top of my desk. 

Q: How will the work at Celtic be different in five years?

A: We strive to keep innovating in our marketing solutions. I want to ensure our clients have the best opportunities to connect their brands with customers. In five years, there will be a significant increase in the intelligence we collect on target audiences in every sector, and we will use that information to drive deeper digital engagement. Measurement has been our greatest asset for optimization. 

Q: Does the agency do pro bono work?
A: We support organizations that the Celts are passionate about. My passion is NPH USA, an organization that supports orphanages in Central and South America. In fact, my family includes Samuel who came from the NPH orphanage in El Salvador.
