Karleen Kos, CAE, PSAI Executive Director

Karleen joined the PSAI in January 2014. As Executive Director, Karleen leads the organization by developing and implementing strategies to realize the PSAI vision and mission. She is responsible for activities aimed at membership growth and retention, program development, support for daily operations, and increased organizational visibility. Karleen also partners with subject matter experts on the Board of Directors, with Past Presidents, committees, volunteers and external partners to increase the PSAI’s value proposition to all its stakeholders.

Prior to her tenure at the PSAI, Karleen worked as the Vice President of Member and Industry Services for ISPE, a large worldwide Society serving the pharmaceutical industry. She is a seasoned leader of not-for-profit organizations with extensive experience as an agent of change and a catalyst for visionary growth. In her previous leadership roles, Karleen has been responsible for strategic and operational planning, business/program development, budget/outcome management, government/community relations, governance and board development.

A Minnesota native, Karleen and her family returned to the Gopher State after a long hiatus when Karleen joined the PSAI team. She loves to travel the world seeing historical sites, gathering recipes to try with brave houseguests, and singing with the Twin Cities Women’s Choir.



Emily Newberg, Director of Membership and Credentialing

Emily was welcomed to the PSAI in August 2017. Her role involves overseeing and maintaining the databases, answering information inquires, processing memberships, sending out mailings, and making sure the office stays running smoothly, among other responsibilities.

Emily has a degree in global studies with an emphasis on environment and development in Africa. Her background includes experience in customer service, volunteer training, community organizing, and environmental activism. In her spare time, Emily enjoys running, biking, reading, all sorts of travel, and playing with her two young kids.



Rand Retterath, Director of Marketing

My professional background includes 20 years at the Minneapolis Star Tribune, the largest daily circulation newspaper in Minnesota. While there, I held a variety of positions within sales and marketing as well as consumer promotions. Some highlights include sustained revenue growth in classified ad volume in a tanking market; a first-of-its-kind, one-year price-elasticity study in conjunction with Harvard University, and extensive research into the senior-housing segment — which led to the new publication Senior Living Showcase.

Most recently, I was the marketing manager for a family-owned, pet- and hobby farm-supply wholesaler as well as start-up lead for an off-site, new-business enterprise. Academically, my education culminated in an MBA from a local state university. In my spare time I am an avid reader, play bagpipes (in the past I was a member of Minnesota Police Pipe Band and Macalester College Pipe Band), exercise regularly and do volunteer outreach in a variety of disenfranchised communities. Above all that, my greatest role was that of a parent to an amazing young man who never ceases to make me proud!


Craig Robert Marson, Communications Manager

Craig started at the PSAI in October 2018 as the communications manager. In this position, Craig will spearhead various communications strategies as part of the PSAI’s future marketing goals. Craig will attend and create materials for all PSAI events as well as provide strategic planning, graphic design, and social media outreach.

Craig has a Bachelor of Science in Technical Writing & Communications with an emphasis in Information Technology and Design from the University of Minnesota. His professional background includes event coordination, digital marketing, and customer service. In his free time, Craig enjoys going to concerts, traveling, biking, and anything outdoors.
