Tolentino O.
We consistently have an outstanding experience at Just Kids Pediatrics in Mission. As a solo mother of three children—ages six to one and a half—I know firsthand how stressful dental visits can be. However, the team at Just Kids Pediatrics makes the entire process seamless. Their kindness, patience, and genuine care put my children at ease, turning what could be a difficult visit into a positive experience. In fact, my kids enjoy their time so much that they look forward to coming back—something rare when it comes to dental appointments. The level of service and compassion provided here truly sets them apart. Thank you so much to Dr. Avula, Josie, Janae, Jasmine and Amy!!

Incredibly kind and attentive staff. I brought my 16 month old daughter here for her first dental visit/ cleaning. I learned a lot, was able to ask questions, and my daughter had a great time, with lots of smiles. A huge thank you to the staff at 'Just Kids Pediatric Dentistry in San Leandro. Will be sure to continue coming back here - kudos to the team!
Katie C.
My new favorite kid dentist. Took my son here for his first ever dentist visit and it was a great experience. He’s 1 so of course he has no idea what’s going on, but they gave him a shirt and a prize at the end and they even took a picture of us at the end and put it on a magnet to take home, so cute. I love the staff here, they ask great questions, very tentative and make you feel like you’re not a new patient but your family. We will see you all again in 6 months for his next cleaning! Highly recommend them for a kid dentist!
Patty M.
My child walks out of this office with a (shiny) smile each time. Wish I had a pediatric dental office this great when I was growing up. I’m happy my child has a positive association with going to the dentist. Keep you the great work!
Megan L.
My daughter absolutely loves coming here. After what could have been a traumatizing experience for her at a previous dentist (because it was for me), I was recommended Just Kids by several other parents, and we have been so pleased with our experience. My daughter is so excited to go to her checkups, and has even asked if we could get to the appointment early so that she could play the games in the lobby. Everyone that works there is incredibly kind and welcoming and Dr. Chang is great. They truly know how to make the dentist experience fun for children. Thank you!
Response from the owner:Thank you, Megan, for your wonderful feedback! We're thrilled to know that we could transform your child's dental experience. Our team is dedicated to creating a friendly environment for kids. We look forward to seeing you again!

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.
