Welcome to Iliff

“Iliff is a small institution with a large purpose. It addresses complex problems in diverse settings with a historical commitment to diversities and justice and peace.”

Tom Wolfe, Iliff President


Founded in 1892 by Colorado Seminary (now the University of Denver), and incorporated as an independent institution in 1903, Iliff has been on the forefront of graduate theological education. Related to the United Methodist Church, Iliff serves more than 30 denominations and faith traditions.

The school is an important place for dialogue and understanding about many of the most important issues that face the world today. For more than 125 years, Iliff has been at the forefront of theological education. It is recognized nationally and internationally for its emphasis on peace, justice, and ethics. It is also ranked in the top 10 theological schools engaged in multi-faith education by the Auburn Theological Seminary as well as being named one of the Seminaries that Change the World in both 2015 and 2016.

Simply put, Iliff is a great place to question and learn about the issues that have faced the world. At Iliff, we recognize that dialogue is important, no matter how complicated or uncomfortable that may feel. Most importantly, though, we understand that change starts with you and your leadership.

As one of the best theological schools in the nation, the school offers a diverse community in a beautiful Denver, Colorado setting that is supportive, challenging, progressive, and enriching for students. Courses are offered on-campus, online, or in hybrid formats.
