The Children's Course is located in a beautiful setting nestled between the Clackamas and Willamette Rivers in Gladstone.  It originally opened for play as Rivergreens Golf Course in 1961 as an 18-hole, par 3 course under the ownership of Charlie Thomas.  In 1989, following the development of the apartments on the perimeter, the course was redesigned into a 9-hole, par 3 course and became the Rivergreens Golf Club.

In 1996, the course became dedicated to children due to Duncan Campbell's dream. While playing golf in Scotland, Duncan, a successful Portland Business owner with a passion for helping children, noticed a number of children's golf courses.  He dreamed of one day making the concept a reality in Portland.  After a two year search, Duncan became aware of the potential availability of the Rivergreens Golf Club and made an initial offer.  The Thomas' had a strong sentimental desire for the property to remain a golf course and they accepted Duncan's offer.  Operation of The Children's Course began on June 30, 1996.

In 2000, The Children's Course became a chapter of The First Tee organization and in April of 2011, The Children's Course merged with The First Tee of Portland and became The First Tee of Greater Portland.
