    Dr. Go is awesome! He really, really cares about the quality of his work and about his patients…read more Super personable and just super chill and positive. I remember calling the office to reschedule after they had already closed, expecting to leave a voicemail, but Dr. Go personally picked up the phone and cheerily rescheduled me! During COVID, my dental hygiene was abysmal - I was constantly on cough drops and was drinking sweetened ginger tea 24/7. I went to Dr. Go after going to another dentist in Brea (Dr. T) that was not so great and wanted me to get braces first, as a full grown adult, before I could even get a simple cleaning. So...I went into the office filled with shame and dread. But Dr. Go and the staff were so incredibly warm, kind, and understanding, and my fear of judgement melted away. The office and equipment were also very clean and modern. I walked away confident, with super clean, bright teeth that I ended up taking very good care of every single day after my cleaning! It's been years and zero cavities since!

    I was a patient to this office when it was Dr Ivar Vasco who was the primary dentist. He retired…read moreand it's now Dr Goh who is the dentist and I can't give enough praise to him for his next to painless care. He's friendly, professional, and his work is top notch. He makes it a priority to make sure pain is to a minimum. I highly recommend this office and although I live miles away in Whittier I still make this office my first choice for any dental work needed. By the way the staff are friendly and exceptionally helpful.

    I have been with Dr. Chang for over 20 years, and I can honestly say she is one of the most caring…read moreand trustworthy dentist I have ever met. What I appreciate most is that she never over sell any treatments. She always presents all of the available treatment options and takes the time to explain the pros and cons of each one in a way that is easy to understand. I never feel pressured into making a decision and I always feel informed and confident about my treatment choices. Every visit feels personal. She listens carefully, answer questions patiently, and genuinely cares about her patient's well-being. It's clear that her priority is what is best for the patient, not what is most profitable. After 20 years, I still trust her completely with my dental care. She's honest, knowledgeable, compassionate, and truly puts her patients first.

    The best dentist! I had a dentist in Fullerton years ago and when he retired I struggled finding a…read moredentist who was as thorough, gentle and caring as him and his team. The reason I kept going back to his office was bc I always had the same dental hygienist so it felt familiar whenever I went every six months, but I'm Happy to report that I've found my new fave dentist office! Christine and her team are all so nice, and it doesn't seem like a rotating door here - the staff here are consistent and welcoming! Christine takes her time to listen to your concerns and what's key here is that they're always on time. I've never had to wait in the waiting room a long time unlike some other dentist offices (looking at you Anaheim hills dental group.. )! Also never felt pressured to do any treatments I didn't feel ready for. They are pretty kid/toddler friendly as well. My daughter's first dental experience was here and it went great; she has no fears about the dentist and loves the little treasure box she can pick from after her check up.
