Steffi G
Best pediatric dentist there is in Fremont. My kids are looking forward to their routine exams every time.
Dana R.
I was hesitant to try a new dentist for my children after moving. I considered continuing where we were but my experience made me thankful and I’m looking forward to having a trustworthy place I can take my 3 children to.
Bridgett B.
Very good and sweet people. My daughter is one and it was her first appointment and Dr. Tab is so sweet and great with kids! They also gave her the cutest little shirt that she’s obsessed with ☺️
Joyce
July 2025 Update: My family has officially graduated from Just Kids Pediatric Dentistry with my youngest turning 18 and going to his last dental appointment at this wonderful office. We will miss you, Dr. Jonathan & Associates, the incomparable Dr. Steven Chan, Arvee and the caring staff at Just Kids! Twenty-one years went by so fast! ~ Very affectionately, the Pena Family
----------------------------------------------------------------------------------------------------
We have been with Just Kids since 2004 and absolutely love this practice! My only regret is that my children are now aging out…I used to bring all three of them at the same time, and now I only have my sixteen-year-old there. We have seen Just Kids grow and expand over the years, but Dr. Jonathan and his team never fail to offer excellent care and attention and have always treated us like family. They are truly the best!
Natasha S.
It was my son's first dentist appointment and he was thoroughly at ease the whole time. They make it an enjoyable experience for the kids with balloons, coins that can be traded in for a treat, and great service. Definitely will be going back!
Lan L
the staff is so friendly from the moment you first walk in and welcomes you in. dds and hygienist were both so professional and thorough with the procedures!!
MEHULKUMAR K.
Execellent Experience.
The place where your child can be easily comfortable.
Co operative and nice staff. Thanks!
Mary H.
We had a great experience! The staff was so patient and kind, and they really know how to make kids feel comfortable. The office is clean, colorful, and super kid-friendly. My 19 months old cried during his cleaning but it was expected. He enjoyed the dog balloon and the kids wall at the end of the visit. Highly recommend for any parent looking for gentle, professional care!
Response from the owner:Thank you for your wonderful review, Mary! We're thrilled to hear that your child had a positive experience with our team. We look forward to welcoming you back for future visits!
Tracey
Great first experience at this office for my 2 kids! Everyone was so friendly and very efficient! They loved the balloon animals and toy wall at the end!
Response from the owner:Thank you, Tracey! We're thrilled to hear your kids had a great experience with us. Our team loves making visits enjoyable, and we're glad they enjoyed the balloon animals and toy wall!
Vinoth Baalaji A.
It was the first visit for our 2 year old. It was a pleasant experience.
Response from the owner:Thank you for your wonderful review, Vinoth! We're delighted to hear that your child's first visit was a pleasant experience. We look forward to welcoming you both back for future appointments!
H. Q.
Wonderful for my 4 year old! Very fun, professional, and stress free children’s dentist. 🦷
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear that your child had a fun and stress-free experience with us. We look forward to seeing you both again soon!
Jaqueline C.
My daughters first time at Just Kids Pediatrics Dentistry and Ortho, very friendly staff, very clean office. My daughter gets really nervous when it comes to dental work but she felt at ease through the whole process. Will definitely be recommending to family and friends.
Response from the owner:Thank you for your wonderful review, Jaqueline! We're thrilled to hear that your daughter felt comfortable during her visit. We appreciate your recommendation and look forward to seeing you both again soon!
Patricia N.
Dr. Lee was very patient with my son. She knew he was nervous about the dentist, but she let him choose what he was comfortable with. She never forced him to do anything he didn't want to do like x-rays or actually using the tool to clean. I love going to Just Kids because they are very accommodating to kids.
Response from the owner:Thank you for your wonderful review, Patricia! We're thrilled to hear that Dr. Lee made your son's visit comfortable and enjoyable. Our team is dedicated to creating a positive experience for all children.
Surat S.
Excellent experience with Just Kids. Doctors and nurses are very caring and take care of kids very well.
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear that you had an excellent experience with our caring team. Your child's comfort and well-being are our top priorities. We look forward to seeing you again!
Patrick B.
My son is excited to go the dentist. He likes X-ray machines and loves the tv’s on the ceiling.
Response from the owner:Thank you for your wonderful feedback, Patrick! We're thrilled to hear your son enjoys his visits. Our team aims to make every dental experience fun and enriching for kids. See you next time!
