In 2002, a 56 acre tract of land became available at the corner of Mills and Mooresville Road and was purchased in 2003.  In January 2005, zoning was approved for the new church and in February Archbishop Buechlein granted permission for the parish to purchase the land. 

In 2007, Rev. Harold W. Rightor II became the Associate Pastor of St. Ann's. He continued as Associate Pastor through mid 2009, when he left to preside over another parish.

The building project accelerated in 2008 with the sale of the church on Holt Road and on June 29, 2008, a procession of cars moved from the church to the new site for the Ground Breaking Ceremony.  Rain, rain and more rain delayed the opening of the new church through June and into July, 2009. 

In celebration of the opening of the new church, a video covering the history of St. Ann was made to commemorate the occasion.

On Saturday, September 26th, 2009, Archbishop Daniel Buechlein formally blessed the new building of St. Ann Catholic Church on the corner of Mills and Mooresville Road in Decatur Township, Indianapolis, Indiana. 

On July 3, 2012, Father Glenn was reassigned to St. Susanna's Parish in Plainfield.  Rev. Robert T. Hausladen became the new pastor of St. Ann's.

The COVID-19 pandemic began in early 2020, forcing major restrictions on attendence at church. Meetings were done virtually via the internet, and Masses were streamed on Facebook. Restrictions began to lift in spring of 2021, but a nearly full return to normal wasn't realized until summer of 2021.

Fr Francis held his last mass at St Ann the weekend of July 4, 2021, as he had been reassigned to St. Pius X. Fr. Jude Meril Sahayam then became the new priest at St Ann & St Thomas More.
