Brea Ranch Dentistry

Great service, knowledgeably and the friendliest staff. Dr. Karen and Dr. Johnny Koo are professional and care very much about the patients.

Dr. Karen and Marissa are just the best. Super sweet and very nice. They are patient and kind.
I love coming here for my dental work. They are the best. Shout out to the front desk!! They rock

I’ve only been coming here for a year but Brea Ranch Dentistry has been great. Dr. Johnny has a great bedside manner and a skillful touch. The rest of the staff are efficient and kind. Definitely recommend!

Wonderful dentist! Karen and Johnny run a fantastic practice. They provide great care, honest about what work you need and always looking out for whats your best dental health. Definitely will be a repeat patient and will recommend them to anyone looking for top quality care and service. Also on my most recent visit in June 2020, I felt extremely safe becuase of their multiple covid safety and health precautions.

Phenomenal dentist office! I went in for a couple of cavities, and can't say enough good things about my experience. The staff was warm, friendly, and super easy to talk to. The doctor was really personable and explained what he was doing through the entire process. If all dentists operated like these guys there wouldn't be such fear of dentists. 10/10 would recommend.

Highly recommended dental office where they take excellent care of all dental issues, are very conscientious about explaining everything that needs to be done, and are extremely trusting on costs charged. We drive over 60 miles one way to this office because of their high integrity. It is really difficult to find an office so trusting and caring about your dental health.

I am so afraid of the dentist, and it’s been a while since I’ve had a checkup and cleaning! I researched dentists in Brea and decided on Brea Ranch. I was nervous but I went. I’m so glad I did!!! I adored the staff! I loved the dentist! I loved that it’s in Brea! I didn’t feel a thing and the dentist was very thorough. My husband has an appointment coming up as well. I’m just so relieved.

Dr. Karen is very nice, genial, and professional. She is very patient and fixed my cavities perfect.

Very professional and personable... fast and friendly... definitely recommend them

Recently I’ve had two emergency dental needs, a root canal, and recently my daughter accidentally chipped my front tooth, they got me in ASAP which was maybe a week out and had my tooth fixed within an hour and then gave me the gentlest cleaning I’ve ever experienced!
Everyone there is sooo welcoming and kind, it’s very judgement free and they are really honest and clearly actually love their jobs and want to help
Highly highly recommend this office
