Dr. Jonathan Chang

Just Laughs, Just Smiles, Just Kids!

Dr. Jonathan Chang

DMD

Location: Downtown

I am so excited to part of the Just Kids Pediatric Dentistry family! As a board certified pediatric dentist, I feel privileged to be able to help kids cultivate a lifetime of great oral health. I promise to care for your children as if they were my own.

A little bit about me: I grew up here in the Bay Area, attended college at UC Davis, and went on to obtain my Doctor of Dental Medicine degree at Temple University in Philadelphia, Pennsylvania.

It was in the city of brotherly love where my passion to work with children was born, and I went on to specialize in Pediatric Dentistry at UCLA. While in LA, I was on staff at the Ronald Regan Mattel Children’s Hospital and was privileged to be able to work alongside some of the best pediatric dentists and pediatricians in the world. Although my adventurous side has brought me all over the United States, my heart has always been in the Bay Area.

In my free time I am a huge Warriors, 49ers, and A’s fan! I like hiking, swimming, and watching the History Channel.

My professional interests include involvement in the American Dental Association, California Dental Association, American Association of Pediatric Dentistry, and California Society of Pediatric Dentistry.

Sarah C.
Kind dentists and dental hygienists. The staff are very thoughtful and go above and beyond to create a welcoming environment for kids.
Lisa K.
Just Kids have been welcoming since our first visit. Our first visit with our now 4 year old had been the same as his second. He leaves with gifts and he loves that. A balloon, new tooth brush, floss, stickers and a coin for the vending machine. He has zero cavities and he sat sooo still and followed directions. I made my first time mistake by not preparing him for the visit so he was very nervous the first time. This second time I prepared him and talked about the dentist that he remembered from his first visit. He was nothing but excited to visit. From the dental assistant to the doctor the are nothing but professional and kind. Thank you so much for taking care of us.
Fatima M.
My daughter loves it ! Dulce has been really kind with her and Bryan Chao has been seen her for most of her treatment and makes her feel comfortable and reassures her how strong she is . It has not been easy for my daughter due to the complexity of her treatment but she has not once complained . Excited to transfer my other daughters here as I know they too will love it .
Response from the owner:Thank you for sharing your wonderful experience, Fatima! We're thrilled to hear that Dulce and Bryan have made such a positive impact on your daughter's treatment. It's great to know that she feels comfortable and reassured during her visits. We look forward to welcoming your other daughters and providing them with the same level of care!

rachelle R.
My daughter was so nervous about getting 2 teeth extracted, to be honest, so was I.
Thankfully, I can always depend on the staff at Just Kids to make us feel comforted, supported, and at ease.
Our appointment time was held, our dental assistant Alondra was accommodating, kind, efficient, and communicative the whole way through.
Dr. Ratan is an absolute star! She’s the best! My daughter and son always look forward to seeing her. She has a mother’s touch and nurturing tone with the kids. We completed 2 extractions without any tears or complaints.
It matters so much to me that the kids are able to have healthy experiences at the dentist and I’m thrilled to say they do because of this team.
Special shout out to Amy!
Response from the owner:Thank you for your 5-star review!

Response from the owner:Thank you for your wonderful review! We're thrilled to hear that your children enjoy their visits and have fun with our activities. We look forward to continuing to provide a positive experience for your family!
Аnna М.
I cannot recommend Just Kids Pediatric Dentistry highly enough! Our recent visit was truly one of the best experiences we've ever had with our children at a dental office. From the moment we walked in, the staff was incredibly welcoming and understanding, putting both me and my kids at ease. The dentists and hygienists were fantastic with the children – patient, gentle, and remarkably skilled at making the visit fun and smooth. My kids actually left excited about their next check-up! This clinic genuinely transforms what can often be a daunting experience into something positive and stress-free. If you're looking for top-tier pediatric dental care, this is absolutely the place to go.
Response from the owner:Thank you for your wonderful review, Anna! We're thrilled to hear that your family's experience was so positive. Our team is dedicated to making dental visits enjoyable for children. We look forward to seeing you again!
Elena L.
Excellent experience with this dental office. I was happy that there was no pressure on trying to upsell on unnecessary treatments. The last two dentist office I took my son to for just basic checkup always turned into being pressured into doing unnecessary treatments. Loved the staff and Dr. Jeffrey Chang was great. :)
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear you had a positive experience with Dr. Chang and our team. Your comfort and trust are our top priorities. We look forward to seeing you again!
carl U.
Thank you Just Kids Pediatric Team (Dr. Joanne Lee and Carl) not only, courteous and professional but also friendly and patient. Keep up the excellent work.
Alysha B.
Liz and Dr.Bryan always make our visits fun! My now 4yr old has been coming here since he was 1 and I’m positive that the slow introduction to all the tools and the dental cleaning experience helped avoid any fears of going to the dentist. He gets excited when he knows he has an appointment coming up and absolutely loves the fun prizes he gets to pick at the end 😊
Response from the owner:Thank you for your wonderful review, Alysha! We're thrilled to hear that your son enjoys his visits and feels comfortable with us. Creating a positive dental experience for kids is our top priority!
Mike T
My kids love it here. Clean and very polite from the moment you walk in.
Response from the owner:Thank you for your wonderful feedback, Mike! We're thrilled to hear your kids enjoy their visits. Our team is dedicated to providing a clean and welcoming environment for all our young patients.
