About William Sanfilippo, NYS Licensed Real Estate Salesperson

I’m a full-time real estate professional helping clients buy and sell residential properties across Long Island. With over 11 years of experience in sales and customer service — and a prior 35-year career as an Executive Chef — I bring dedication, precision, and tireless energy to everything I do.

My mission is simple: to serve every client with integrity, intelligence, and skill. Whether you’re purchasing your first home, upgrading for a growing family, downsizing after the kids have moved out, or investing in property, I’m here to guide you confidently through every step of the process.

I stay current on all real estate laws, regulations, and market trends to ensure that my clients make informed, comfortable decisions. I take pride in my expertise with VA home purchases, working effectively within the unique requirements of the VA mortgage system to help returning veterans find their perfect home.

Relentless in pursuit of the ideal match, I believe every buyer and seller deserves transparency, trust, and top-tier service. My clients appreciate not only my professionalism but also the personal care and guidance I bring to one of life’s most important financial decisions.
