John M. Krieger

Executive Director

John M. Krieger, J.D., LL.M. is Executive Director of WorldDenver. Krieger holds a Master’s of Law in International Law from American University and a law degree from University of Richmond. Over the last 12 years, he has held multiple leadership positions focused on communications, outreach, staff development, and membership growth at national and Colorado-based non-profits. Most recently, he was Director of Campaigns at ACLU of Colorado, where he led communications strategy, volunteer recruitment, outreach, education, and community events during a period of more than 500% growth in membership for the organization.

Previously, Krieger was a staff attorney, lobbyist, and Communications Director for the United States Public Interest Research Group in Washington D.C., where he led successful media and grassroots organizing campaigns on issues ranging from public health and product safety to eliminating waste and fraud in federal contracting. He directed a national field campaign to create the Consumer Financial Protection Bureau, which The Hill recognized as one of the top 10 lobbying victories of 2010.

Krieger has served on the Alumni Board of Directors for Flagler College, from which he earned an undergraduate degree in journalism and public relations in 2002 and was recently named one of the institution’s 50 Alumni of Distinction.

Lauren Osga

Director of Development & Communications

Lauren joined WorldDenver from the World Affairs Council of Charlotte, where she served as the Senior Director of Programs & Development. She brings experience in planning and executing over 40 programs per year, including two major annual fundraisers, and young professional engagement and development. 

Lauren grew up in San Diego, CA and attended a French immersion school for K-8 grade, which planted the seeds for her passion in diversity and cross-cultural experiences. She earned her B.A. in International Studies and French, with a minor in Religion from California Lutheran University where she had the privilege of participating in travel seminars to Jamaica, Italy, and a semester abroad in Dakar, Senegal focusing on issues affecting vulnerable children. She completed a dual masters degree program in Social Work (MSW) and Theological Studies (MTS) at Boston University, with a focus on nonprofit development and program administration. During her time at BU, she participated in a travel seminar to Israel and Palestine to explore complexities of peace building, and one to Turkey to learn about the intersection of ancient archeology and modern Europe. In Boston, she worked in community organizing with Greater Boston Interfaith Organization and at DOVE, Inc., a domestic violence resource agency, where she contributed to planning and development for two record-breaking fundraiser events.

Lauren lives in Denver with her husband and daughter and enjoys the performing arts, live music, backpacking, snowboarding, and all that the CO Rockies have to offer.

Sarah Wilkinson

Director, International Exchange Programs

Before joining WorldDenver, Sarah Wilkinson founded what was initially called Project PeacePal in 2006 to connect students directly with peers in countries across the globe through hand-written pen pal letters. By 2016 she had expanded the network to over 18,000 participants in 31 countries, and grown the organization to include in-person international exchanges, rebranding as Global One to One.

She earned her B.A. in cultural anthropology from the University of Illinois at Urbana-Champaign, and completed her Masters in Public Administration from the University of New Mexico, with the thesis topic “Developing Intercultural Understanding and Communication with Adolescents through Virtual Exchange.” Sarah is passionate about building global connections that celebrate our common humanity, and is excited to continue developing relationships with existing and new partners in her position with WorldDenver.

In her free time she enjoys hiking, snorkeling in the ocean, and laughing with friends and family.

Shannon Payne

Senior Program Manager, International Exchanges and Advocacy

Shannon joined WorldDenver in January 2020, shortly after graduating from the University of Denver with her M.A. in International Studies. On the WorldDenver team, Shannon oversees the International Visitor Leadership Program (IVLP) and advocacy efforts. She was born and raised in England, where her family lived until they moved to Hampton, Virginia when she was 13. (Unfortunately, she no longer has a British accent.) Before moving to Denver, Shannon spent six years in Orlando, Florida. She received her B.A. in Anthropology from the University of Central Florida and worked at UCF’s Global Perspectives Office for two years. Previously, Shannon was an intern and then a member of WorldOrlando, where she helped to host international visitors through the IVLP. As a child, Shannon visited the United States most summers and traveled with her family throughout Europe and to Mexico and Belize. She completed a summer internship in the Cultural Diplomacy section of the U.S. Embassy in Moscow as an undergraduate and, during grad school, she spent two weeks in Israel and Palestine to learn firsthand about conflict and peacebuilding in the region. She has also road tripped to and across most of the continental United States. Shannon has studied French, Russian, and Latin. In her free time, Shannon enjoys exploring Denver, hiking in the beautiful Rocky Mountains, playing video and board games, and planning her next vacation.

Talia Reynolds

Manager, Membership & Events

Talia joined WorldDenver in June 2018 as the Development & Communications Intern before officially joining the staff in January 2019. She is a graduate of the University of Denver with a B.A. in International Studies and Spanish. She is a Colorado native, born and raised in Crested Butte before she moved to Denver to begin school. She lived in Argentina for a year through the Rotary Youth Exchange Program and studied abroad in Spain for a semester through her university. In addition to traveling as much as she can, Talia likes to spend her time exploring the mountains of Colorado and the culinary delights of Denver.

Liz Shaw

Senior Program Coordinator, World Affairs Challenge

Liz grew up in Virginia and earned a BA in Psychology from the University of Virginia before moving out to Colorado. Her passion for international travel was ignited by a trip to Costa Rica during college, and now, like most, her list of want-to-visit destinations is longer than her already-visited list! She finished graduate school at DU in 2018 with a master’s in international development and a specialization in Human Rights and held a variety of different positions before finding her way to WorldDenver as the Education and Exchange Fellow. In her free time, Liz is outside experiencing the variety of activities that Colorado has to offer, reading a good book, and coaching swimming for a local club team.

Keira Chandler

Mission Support Coordinator

Keira joined the WorldDenver team in September 2020 as an intern before transitioning into the role of Mission Support Coordinator in August 2021. She graduated from the University of Denver with a dual B.A. in International Studies and Gender & Women’s Studies. After her first trip abroad to England in 2006, she became passionate about international travel, going to places like Scandinavia, Nepal, Germany, and even studying abroad in Thailand. Growing up in Philadelphia all her life, she was excited to move out west (and get away from the humidity!). When not planning her next trip, she likes to sing, dance, read, and explore the beautiful landscape of Colorado. A fun fact about her is that she has dual-citizenship with Germany.
