The property of The Knolls Condominiums has a long history dating back to the Marian Hills Seminary. In the early 1970’s, the Seminary sold the property to an apartment complex developer and in 1974 through 1975 the Knolls Apartments were built. The Knolls Apartments were converted into a condominium property in 1979, with 600 units housed in 25 residential buildings, the population at any give time ranges from 900 to 1,000 people.

The Knolls has the unique status of being self-managed operating and maintaining approximately 29 acres, 2 miles of sidewalks, 2 swimming pools, a clubhouse and tennis courts. Our residents still enjoy the historical efforts of the Franciscan monks who planted an apple orchard, a pear orchard and promenade walks that represent our current mature trees.

Over the years, The Knolls has grown, changed and developed in conjunction with the Village of Willowbrook.
