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.

Danielle H.
My daughter is terrified of the dentist. This place is amazing! Dr rattan and her assistant Kimberly are just amazing! Patient and kind!
Cody H.
It was our first time here, my baby is almost 15 months and she did amazing! Our dental assistant I forgot her name was so good with my daughter. She spoke directly to her, kept her entertained and was just so patient. I as a first time parents I was so nervous on bringing her to the dentist. Dr. Chang was awesome and was so quick. He was patient with her crying, and was singing to her the whole time.

For our first visit, she got a Tshirt, stickers, a goodie bag, a token to get a prize, and a balloon animal!

They are amazing! Thank you for taking care of us!
LaTasha J.
Friendly staff and very punctual! They make being at the dentist an enjoyable experience for my daughter.
Response from the owner:Thank you for your kind words, LaTasha! We're thrilled to hear that you had a great experience with our staff and appreciated our punctuality. Your feedback means a lot to us!
Gulay E.
Dr. Chang and the team are fantastic! My kids felt completely at ease during the visit, thanks to their friendly and patient approach.

The office is bright and welcoming, making it a fun experience for kids. I highly recommend them for anyone seeking a caring and professional dentist for their little ones. Five stars all the way!
Celine S.
It was 3 and 1 year old’s first time at the dentist and the entire staff was awesome! The office is welcoming to kids and it’s very apparent that all staff are trained for pediatric patients. Both doctors we’ve had are awesome and my kids did great. Special thanks to Liz who always makes my kids feel at ease! She’s the best!
Anna M.
My daughter loved her dental experience because of the professional and friendly staff! The facility was welcoming, clean, and upbeat for kiddos!
Andy N.
Both of my kids have been here since they were 5. excellent services.
Susana T.
Dr. Brian and the team are great with following up with families. We love the family-friendly environment in the office!
Reshma P.
Friendly. Explained everything. Answered questions. Tech was wonderful and engaged with my son. Dentist was wonderful and friendly and fun with my son.
Cindee C.
My 18 month old had his first dental appointment ever here and it was such an excellent experience. They are quick, they give options to the kids and parents to make them comfortable, the explain everything they do, and did I mention quick! I don’t think my son realized the doctor was doing anything to his mouth, he was so gentle. Dr. Brian sang softly to my son while he examined his teeth and gums and answered all questions we had about his dental care. We even got a commemorative photo to put on our fridge to mark the occasion. I’m so glad we came here.
Edith L.
Dr. Chang and the medical assistant were very friendly and accommodating. Thank you for being so gentle and understanding with my son, who is on the spectrum.
yien A.
My kids had a fantastic experience at their recent dental check-ups. Both had their teeth cleaned, and the staff was incredibly gentle and caring, especially with my son who had a cold sore. They were patient and made sure he was comfortable throughout the entire cleaning. The dentist and the team were also great about answering all of my questions and concerns. It's clear they genuinely care about their young patients. I highly recommend this practice!
Sandeep H.
My son and daughter have been patients at Just Kids Pediatric Dentistry & Orthodontics since their very first visits, and we’ve always had a wonderful experience. Dr. Rattan is kind, relatable (as a mom herself), and truly knows how to connect with kids.

Today, my son was cared for by Alondra, RDA, and Dr. Rattan, and they made what could have been a stressful visit into a comfortable one. My son was nervous, but with their patience, kindness, and encouragement, he felt at ease throughout the process. Dr. Rattan even gave him the confidence to have his loose tooth extracted, something he was completely opposed to before coming in.

At Just Kids, treating children with respect and nurturing them through the process comes naturally, and it shows in every interaction. I’m grateful for the care and highly recommend this practice!

P.S. the prizes help too :)
Jacqueline S.
My daughter loves coming to her dentist and I couldn’t be happier!
