About Us
Drs. Karen and Johnny Koo are your trusted husband-and-wife dental team, dedicated to providing comfortable, quality care tailored to your unique dental needs. The Koos met and began dating after their freshman year at Loma Linda University School of Dentistry and were married shortly after their graduation in 2003. Along with their two young daughters, they reside in North Orange County, and have operated Brea Ranch Dentistry since July of 2012. Though they only recently took over the practice, they are pleased with the positive reception and extremely touched by the support and kind words from their patients and staff. Their goal is to provide you with a positive dental experience, a healthy smile, and a trusting relationship with their friendly, caring team.
