Find Your New Home

Welcome, and thank you for stopping by. If you're looking for a REALTOR® who genuinely knows Napa Valley — not just the market data, but the neighborhoods, the streets, and the community — you're in the right place.

I'm Dean Castelli, a Northern California native and REALTOR® with Windermere Napa Valley Properties. Before real estate, I spent 25 years in hospitality management, where I learned that great service isn't about transactions — it's about people. That philosophy shapes everything I do, whether I'm helping a first-time buyer find their footing in a competitive market or working with a longtime owner ready to sell with confidence.

Real estate is one of the most personal decisions you'll ever make, and I take that seriously. With a 4.9-star rating on Zillow and a track record built on repeat clients and referrals, I'm proud that most of my business comes from people who've worked with me before — or been sent by someone who has.

I'd love to earn your trust too. Let's start a conversation.
