Meet Louisa

With a full-service, boutique approach and a distinct analytical edge, Louisa Gillen delivers exceptional results for buyers and sellers across New York City. As co-founder of SIMPLE Real Estate, Louisa brings over 20 years of experience and more than 850 successful transactions to the table — along with a smarter, client-friendly commission model designed to reflect the realities of modern real estate.

Louisa’s background in mathematics (BS, Vanderbilt University) forms the foundation of her data-driven approach. Equal parts strategist and trusted advisor, she provides tailored guidance rooted in market trends, property-level insights, and financial precision — while never losing sight of the human side of each transaction.

Raised in Carnegie Hill and now a longtime Greenwich Village resident, Louisa has a deep, intuitive understanding of the city’s most sought-after neighborhoods, from the Upper East Side to Tribeca and beyond. Her ability to decipher the nuances of buildings, blocks, and buyer psychology gives her clients a true competitive edge — whether she’s positioning a prewar co-op for top-dollar sale or guiding a family through a seamless purchase.

Clients describe Louisa as clear-eyed, compassionate, and fiercely committed. She’s known for her ability to simplify even the most complex deals, offer candid perspective, and stage + style spaces with elevated design sensibility.

When not advising clients or negotiating deals, Louisa spends time in Quogue with her husband and two children, enjoying golf, tennis, skiing, and architecture. She believes real estate should be transparent, intelligent, and — above all — SIMPLE.
