Puts You First

For more than 25 years, the Diamond Key Team has helped buyers and sellers navigate Central New Jersey real estate with confidence. Founded by Broker Christina Duncan, our award-winning team has sold more than 1,000 homes, combining deep local knowledge with the resources and support of a full-service real estate team.

It’s about listening to your goals, providing clear guidance, and being there from the first conversation through closing and beyond. With 65% of our business coming from past clients and personal referrals, we’re proud to build relationships that last well beyond the sale.
