Marianne D. Koushouris 

Founder/Principal Designer

Marianne's appreciation for great design and beautiful spaces started long before her studies in Florence, Italy - it's genetic.  As the daughter of an Italian immigrant (an exquisite tailor of fine clothing) and a Bostonian (the Italian Martha Stewart), she was surrounded by beautiful clothing, interiors and music at a very early age.  Her self-taught sketching and spacial planning skills stem from her dapper uncle, a talented architect in Massachusetts and Rome.

Marianne started building her skill set as the Merchandiser and Display Manager for Barneys New York in Westport, Connecticut. A two year hiatus as a merchandise coordinator for Calvin Klein would further hone her skill for creating spaces of visual beauty while balancing the relationship of fabrics, fixtures, furniture, lighting and finishes.  Barneys New York asked her to return to oversee a talented group of display managers in the field as the company expanded nationwide.  She directed floor and fixture layouts, window presentation and all interior visuals.  BNY was a collection of creative geniuses and a world of inspiration all in one place.

Marianne's desire to move closer to home in Greenwich brought her to Waterworks, where she spent five years as Director of Merchandising for the growing, luxury purveyor of the finest fixtures, surfaces and merchandise for the bath.  Prior to starting a family, she spent her last year at Waterworks focused on bathroom design, where beauty, function and attention to detail must go hand-in-hand.

In addition to being passionate about great design, Marianne is addicted to sourcing all things vintage and can be found two days a week at The Collective in Stamford. She loves traveling, especially to Italy, and enjoys summer days with her family and black lab Luna at her home in Stonington, Connecticut, where nature’s beauty has no limits.
