Dentists in Castro Valley, CA

Dr Kang is great. I thought deep cleaning would be painful afterwards. Turned out no pain, just little sensitive. Staffs are friendly.

Timely and efficient

Very knowledgeable staff, extremely punctual and really friendly. Listen to concerns and helpful all at the same time. I have been telling my friends and coworkers about the Castro Valley site.

Great dental service all the time!

I like the staff and dentist very friendly and professional

First appointment and everyone made me feel very comfortable and welcomed. They listened to my concerns and Dr Kang and Elizabeth at reception explained things and answered all my questions. They were patient and kind.

I'm very pleased with the service I received from Bright Now Dental keep up with the good job

Scheduling was easy,
I arrived 15 minutes early for my 8am appointment.

Employees waiting outside to be let in.

Got inside wasn’t spoken to by front desk.

Waited 5 minutes before going up to talk to the counter as I wanted her to settle in.
She first spoke to the gentleman who entered after me.

I had my intake form done in 5 minutes as it was my first time visiting.

Over 30 minutes before I was seen.

Assistant was friendly enough. No one seemed to know why I was there.

Dr Kang is the reason for the high star rating/review.

She previously took care of my daughter and I felt the same level of care from her.

Will give them another chance to earn my business

Very helpful and professional.

Nice friendly staff. Very knowledgeable. Clean comfy environment 😊

Great experience, can’t remedy dentist name but what I do remember was her enthusiasm about her profession which I appreciate. I love how she told me how and why things were happening.

Appointment went well. Staff very pleasant.

Excellent staff and so close to home. It’s so convenient that I don’t have to drive far. Just got my basic teeth cleaning and they also explain what I need to keep my gums healthy with the right treatment.

I had another positive experience at Bright Now Dental in Castro Valley. I ordered a mouthguard and it seems to be working out really well!
Definitely so far, so good!! 😁

I was pleasantly surprised! 😁 I had a pain-free experience, while taking care of a couple of filling replacements with Dr.Kellie Kang. Everyone was friendly and helpful, including her assistant, Janeth and the receptionists, too.

I was called almost immediately. Everyone was knowledgeable and friendly. Everything went quickly and smoothly.

They are very nice and professional and the work does appear to be a good quality. It is a bit pricey, so I have to mind that.

On time appointment, minimum paperwork, then to business. Very competent doctors and assistants. Caring and attentive to your needs.

I found a truly exceptional dental practice! A welcoming staff who remembers you by name and a skilled, compassionate dentist like Dr. Chang can completely transform what’s often seen as a stressful experience into something positive—maybe even enjoyable.

Her passion for dentistry likely puts you at ease, and knowing you’re in capable hands makes all the difference. I know it is rere to hear someone describe a dental visit as a *pleasure*, but I am. I have definitely stumbled upon something special. I will keep smiling (thanks to Dr. Chang’s excellent work)! 😊

Very pleasant staff,very professional.

Everyone was professional & helpful. The Doctor was gentle & explained the procedure well. 😊

First time coming here and had a great experience. I had a cleaning and fillings done. Dr. Kang and all the staff that I interacted with were friendly and helpful.
