Dan Misleh, Executive Director
Executive Director

I am the founding executive director of Catholic Climate Covenant. What a privilege it is to work everyday with our partners and supporters to share the good news of Catholic teaching on care for creation. Before this job, I spent 11 years in the department of Justice, Peace and Human Development at the U.S. Conference of Catholic Bishops, and three years in the Archdiocese of Cincinnati's social action office. After graduating from Xavier University in Cincinnati, I joined the Jesuit Volunteer Corps, where I met my wife Susie (also a volunteer). I received an M.A in theology from the Franciscans in Berkeley, CA in 1989. Susie and I have three children: Benjamin, Anna, and Zachary. 

Associate Director

I feel blessed to participate in the Covenant’s mission to advance the Catholic Church’s call for us  to love and care for God’s creation, especially for our most vulnerable neighbors.  I seek to affirm the moral, spiritual, and non-partisan foundations of this call, so that we can build bridges across divides and generate durable, compassionate and cooperative solutions to the climate crisis.  

Prior to the Covenant, I have been blessed to serve with the Friends Committee on National Legislation, the National Congress of American Indians, EPA’s American Indian Environmental Office, and the US Army’s 10th Mountain Division.  I am a graduate of Brown University and Villanova Law School, and my family and I are long-time parishioners at the Basilica of St. Mary in Alexandria, Virginia.

Paz Artaza-Regan, Program Manager
Program Manager

I have a deep passion for justice and for the protection of God's creation, and have been blessed with the opportunity to work for 17 years on environmental and human rights issues within the faith community. Originally from Chile, I see myself as a "citizen of the world" with a strong commitment to global, sustainable development. I have an M.A. in International Development from American University, and completed the course work for an M.A. in Community and Regional Planning from the University of British Columbia. Still adjusting to the empty-nest, I fill any "spare" time with tutoring, hiking, knitting, theological and political conversation, long walks with my husband and "Pepper the Pup," and cooking for friends and family. 

Mike Lewis, Director of Operations
Director of Operations

It is a great privilege to work with the Covenant's mission to care for creation and to speak out on behalf of those whose lives have been adversely affected by climate change. As a Catholic with a strong commitment to social justice, I recognize the urgency of Pope Francis’s call to combat the deterioration of the environment and of society.  

Prior to joining the Covenant, I worked for seven years with the U.S. Conference of Catholic Bishops in the communications department. Before that, I held positions in the private sector in document control and document management. I have a BA in English from the University of Maryland and a MA in Publications Design from the University of Baltimore. I am a native of Maryland, where I live with my wife and four children. 


I have served as a consultant to Catholic Climate Covenant since 2009. During that time, I have contributed to the Covenant's public witness and advocacy, media/communications outreach and college/university engagement. In 2017, I became assistant professor and director of the Justice and Peace Studies Program at Creighton University. My research focuses on Catholic Social Teaching and climate change, and I am the editor of All Creation Is Connected: Voices in Response to Pope Francis's Encyclical on Ecology (Anselm Academic, 2018).

Robert Christian, Social Media Manager
Social Media Manager

I am the editor of Millennial, an online periodical by millennial Catholics; a PhD candidate in American Politics at Catholic University; a graduate fellow at the Institute for Policy Research & Catholic Studies; and a father of three. I have a BA from the University of the Pacific in American Politics, an MA in International Security from the University of Leicester (UK), and an MA in American Politics from Catholic University. Care for creation is integral to my commitment to human rights and social justice, which inspires my social media work at the Catholic Climate Covenant. I enjoy spending time with my wife and kids, playing sports, reading, and watching sports, especially the Golden State Warriors.

Ignatian Volunteer

I came to the Catholic Climate Covenant via the Ignation Volunteer Corps, after 27 years at the Environmental Protection Agency.  I have 4 daughters (Anabel, Marisa, Grace and Elise) and my wife Kate and I are parishioners at Blessed Sacrament in Chevy Chase, DC.

Nancy LaVerda
Public Health Volunteer

It has been my pleasure to assist the Catholic Climate Covenant with the development of educational literature that documents the impact of climate change on the health of humanity. I have advanced degrees in public health with a doctorate from The George Washington University and a masters degree from Columbia University. I have worked in the public health field for over 35 years and I’m very happy to use my education and experience to support the mission of the Covenant. I am a long-term parishioner of St. Matthew's Cathedral in Washington, DC, and serve as a member of its Creation Care Team.
