St. Mary's Seminary Renovation/New Construction

Zahner & Associates is so proud to be a part of this local project at St. Mary of the Barrens Seminary in Perryville, Missouri.  It was the first college in Missouri, and the first Catholic Seminary in the Louisiana Purchase, which was chartered here in 1822.

With the 200th anniversary of the Vincentian establishment in the county and the 100th anniversary of the Association of the Miraculous Medal in May, 2018, the time had come to remodel the campus in order to restore the safety and beauty of the site for future generations of visitors from near and far. 

First State Community Bank Project

Our Civil Engineer, Mark McKlin, partnered with the President of First State Community Bank in Perryville to remove a public storm sewer outfall on the Bank property which was causing flooding in the parking lots. He consulted with MoDOT for a new storm sewer to outfall in MoDOT right-of-way. He was also able to persuade the City of Perryville to finance and maintain the new storm sewer.

We are very proud to be a part of this project that is not only a wonderful addition to our community, but that will attract visitors from around the nation and the world to honor our Veterans.  Missouri's National Veterans Memorial will be home to the only full scale, exact replica of the Vietnam Memorial wall other than the Vietnam Memorial in Washington DC.
