About Us

Our Mission

The mission of Big Brothers Big Sisters of Colorado is to provide children facing adversity with strong and enduring, professionally supported one-to-one relationships that change their lives for the better, forever.


By partnering with parents/guardians, volunteers and others in the community we are accountable for each child in our program achieving:

• Higher aspirations, greater confidence, and better relationships

• Avoidance of risky behaviors

• Educational success

In 2014, Big Brothers Big Sisters of Colorado will support at least 1,870 one-to-one mentoring relationships between children facing adversity and adult volunteer mentors, including 1,430 in metro Denver and 440 in the Pikes Peak region. These mentoring relationships will impact youth by helping them to:

  • Improve their sense of self and sense of future.
  • Form positive relationships with peers and family.
  • Avoid risky or delinquent behavior.
  • Achieve educational success.

Our Vision

All children achieve success in life.

Big Brothers Big Sisters of America has been the national leader in youth mentoring since its founding in 1904 in New York City. In Colorado, our history began in 1918 with Claude Blake, chief probation officer in Denver, who watched wartime conditions cause an increase in lawlessness among boys in his community. Recognizing that these boys needed guidance more than critics, Blake established Big Brothers of Denver.

  • The Big Sisters movement was active in Denver from 1921 until about early 1964. A few years later, in the spring of 1969 Big Sisters of Colorado began as a program out of the Southwest Community Center.
  • The Big Brothers Big Sisters-Pikes Peak was formed in 1967 as a program of Family Counseling Service. Later, the program became affiliated with the Pikes Peak YMCA.
  • In 1996 Big Brothers of Denver merged with Big Sisters to become Big Brothers Big Sisters of Northern Colorado. In 1997 it became Big Brothers Big Sisters of Colorado, Inc.
  • In 2001 the organization merged with Big Brothers Big Sisters-Pikes Peak.

Currently operating out of offices in Denver and Colorado Springs, Big Brothers Big Sisters of Colorado is the largest youth mentoring agency in the state. Throughout our history, Big Brothers Big Sisters of Colorado has helped young people overcome tremendous obstacles to become stable, successful adults.
