Don’s passion for real estate started over thirty years ago by initially investing in and developing rental properties in Willow Glen and the Bay Area. Wanting to help his community by sharing his skill and knowledge, he founded Realty World Castlerock in 2010. Actively involved with the Willow Glen Neighborhood Association, Don built a professional reputation on integrity, trust, and strong relationships that span generations.

Now that Castlerock is part of the Sereno family, Don has formed an alliance with Fran. By collaborating together, buyers and sellers benefit from Don’s San Jose area knowledge along with Fran’s extraordinary network and negotiating expertise.
