One documented rude doctor and time management complaints are isolated concerns against an otherwise strong track record.

The clinic sincerely apologizes for the incident. Regarding the deficiencies in our service, all staff are committed to improving and correcting them. We apologize once again to our patients. 🙏
I had a great experience with this dentist! The cleaning was incredibly thorough yet surprisingly quick. You can tell they pay close attention to detail. Just a heads up you’ll need to book your appointment in advance, but it’s absolutely worth it.
Dr. Genius is gentle, friendly, and kind. The toothbrush basin is beautiful, too.
