Waldo is a neighborhood located in Kansas City, Missouri on 75th Street and Wornall Road that has continued to maintain its own unique character, even though it was annexed by Kansas City in 1909. Waldo’s boundaries are Gregory Boulevard on the north to 91st Street on the south (although 89th street forms a full south boundary), and Troost Avenue on the east to State Line Road on the west. In 1841, Dr. David Waldo of Gasconade County, Missouri, was convinced by some friends to purchase land in Jackson County, Missouri. Dr. Waldo purchased 1,000 acres (4.0km2) that ran from what is now Gregory to 91st Street and State Line to Holmes.
