Meet the Staff

The PSAI office is located near the Mall of America in Bloomington, Minnesota. Please get in touch if you are in the area. We’d love for you to stop by!

Karleen Kos, CAE, Executive Director

Karleen joined the PSAI in January 2014. As Executive Director, she 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. She also joins 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 Karleen’s tenure at the PSAI, she worked as the Vice President of Member and Industry Services for ISPE, a large association serving the pharmaceutical industry. She has also served in leadership roles in a health-issue related association, led a charity dedicated to reducing homelessness in a major metropolitan area, and worked in executive roles in mental health organizations.

As a Minnesota native, Karleen and her family returned to the Gopher State after a long hiatus when she 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

The PSAI welcomed Emily 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. In the summer of 2018 Emily also accepted responsibility for coordinating the PSAI’s credentialing program. This means she is your go-to staff member regarding training courses, certification exams, renewals, continuing education credits, and related questions.

Emily has a Bachelor of Arts in Global Studies with an emphasis on environment and development in Africa from the University of Minnesota. Her background includes experience in customer service, volunteer training, community organizing, environmental activism, field work in East Africa, and independent world travel.

When Emily’s not rocking the office she’s usually out looking for an adventure. Whether it’s camping, biking around Minneapolis, hiking in the parks or playing with her two adorable kids, she’s not one to sit still or stay indoors.

Diane holds a Master of Arts degree in English from Michigan State University, and also earned a Social Media Marketing Certificate from Saint Paul College. During her career, Diane has worked for a number of nonprofits producing everything from grant applications to newsletters to quarterly reports to posters, flyers and other creative collateral.
