DIAMOND BAR, CA — October 22, 2026

DIAMOND BAR, CA — In a region where dental appointments often mean squeezing out of work on a weekday morning, the practice of Andriani Ongkorahardjo, DDS, has built its reputation on something refreshingly practical: being open when patients actually need it. With hours that run Tuesday through Friday from 9AM to 6PM and a full Saturday schedule from 8AM to 4PM, the Diamond Bar practice has carved out a distinctive place in the community for patients who cannot afford to treat dental care as an afterthought.
A Practice Built Around the Patient's Week
Dental offices that close their doors at the end of the traditional workweek leave a gap for the parent juggling school pickups, the professional with back-to-back meetings, or the patient who simply prefers not to burn a vacation day on a cleaning. Andriani Ongkorahardjo's practice fills that gap deliberately. By keeping Saturday hours alongside extended weekday availability, the practice has made itself one of the more accessible dental offices in Diamond Bar for patients whose schedules don't bend easily.
"Patients interested in scheduling a visit are encouraged to reach out directly to learn more about services offered, new patient availability, and accepted insurance plans," the practice notes — a simple, direct invitation that reflects the approachable, no-friction philosophy running through the office's day-to-day operations.
A Community Track Record Reflected in Patient Feedback
The numbers behind the practice tell a story of consistency. Andriani Ongkorahardjo holds a 4.4 rating across 34 reviews and carries a Dental.me Score of 91, both signals of a practice that has earned steady trust among the patients it serves in Diamond Bar. In a field where patients often shop around before settling on a long-term dental home, ratings built over dozens of real reviews speak to a pattern of care that keeps people coming back.
The Patient Experience
For prospective patients, the entry point into the practice is intentionally uncomplicated. Rather than navigating a maze of online forms or automated scheduling systems, patients are encouraged to call and speak directly with the office about what they need — whether that's understanding which insurance plans are accepted, learning more about the range of services offered, or simply finding out what openings exist for new patients. That directness, paired with a six-day operating schedule, makes the practice a convenient option for Diamond Bar residents who want dental care that fits around their lives rather than the other way around.
Access and Scheduling
The practice's hours are structured for maximum reach across the week: Tuesday through Friday from 9AM to 6PM, and Saturday from 8AM to 4PM, with Monday and Sunday reserved as closed days for the team. This six-day rhythm, anchored by a full Saturday slate, stands out in a city where many dental offices limit themselves to a conventional Monday-through-Friday calendar. For patients balancing work, school, and family commitments, that extra Saturday window can be the difference between delaying care and getting in to see the dentist promptly.
