Ariston Architecture, LLC is the successor firm of Apostolou Associates, Inc., which was founded in 1972 by Paul Apostolou, AIA. The firm is led by Alexandra Apostolou, who like her father, Paul, is a graduate of the University of Notre Dame School of Architecture.

We pride ourselves on unwavering commitment to client service and superior design. Our firm's broad range of expertise includes commercial, educational, ecclesiastical, civic, athletic & recreational, and healthcare projects. We take a sustainable approach to architecture and planning, and we strive to produce work that will contribute positively to the life of a community. Ecological concerns, operating costs, usage patterns, site considerations, and aesthetic integrity direct our work and let us produce functional, attractive results.
