Meet the 2018-2019 Long Island Liaison Katharine Posillico McGowan

The Long Island Design Community of ASID NY Metro is thriving thanks to the participation of local showrooms, industry partners and ASID designers who volunteer their time for leadership positions. In October 2018, after a very busy and successful year of service, Jackie Higgins of Beach Glass Designs passed the leadership baton to the new Long Island Liaison Katharine Posillico McGowan of Katharine Jessica Interior Design, LLC.


“I am honored to be the new LI Liaison for ASID NY Metro and look forward to working with the entire Long Island design community,” says Posillico McGowan. “I feel that education and communication are essential for successful designers. As the LI Liaison, I will strive to create events that are filled with excellent educational content, relevant topics, as well as, a platform to make invaluable connections. It is going to be an exciting year!"


Posillico McGowan has been involved in the design world for over 20 years, launching Katharine Jessica Interior Design (KJID) in 2003. KJID is a multi-faceted boutique firm specializing in both residential and commercial projects. Posillico McGowan oversees the planning of each project from the start of construction through the finished product. Her attention to detail and ability to mix finishes and materials has led to the creation of elegant spaces that are functional and stylish. Her services span the tristate area where she has a strong following on the Gold Coast of Long Island.


Posillico McGowan’s first design project was when she was 13 years old. “My parents were renovating their home, and they allowed me to custom design my bath and bedroom: Formica platform bed, custom-built wall unit and platform tub. The finished product was my vision and that excited me,” she recalls. “I have never forgotten that feeling.”
