I've been a patient of Dr Yong's since the early 90's; obviously, I'm happy with the services provided. She and her staff are always friendly and upbeat, yet have a sense of humor. For example, several years ago I needed 5 fillings replaced at once and chose to do it all in one appointment. About halfway through, she asked if I needed to go to the bathroom. On returning, I lisped, "If my purse hadn't been in here, I would've made a break for the front door!" and she laughed. All kidding aside, they are concerned about one's dental health without being annoyingly preachy about it, and seem to be up-to-date technologically. Once I didn't get numb properly and she patiently gave me another shot and waited till I numbed up (she said I have an aberrant nerve there). In the past, dentists would get somewhat annoyed and acted like I couldn't possibly be having pain....Great dentist!
