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!
angie N.

This was our baby’s first dental visit at 7 months old, and everyone here was soooo amazing! The office is definitely giving “just kids” vibe, which we loved. The tooth fairies here are super nice and friendly. Dr. Jeff was super friendly and sooo good with our baby!
Response from the owner:Thank you for your wonderful feedback! We are thrilled to hear that your baby’s first visit was such a positive experience. Our team is dedicated to creating a fun and welcoming atmosphere for all our little patients.

Great first time experience at this dentistry today. My son felt so welcomed seeing his name on the board when we arrived - great personal touch!

My personal experience at Just Kids Pediatric Dentist office has been nothing but positive! especially for my two daughters who always look forward to going to their dentist for work. The staff and office vibe in the last few years of coming here with my two children has been nothing but exemplary.

I highly recommend Just Kids Dentistry. It was very easy to make an appointment online, and fill out forms digitally. They made my son feel very welcome and comfortable, and he loved the prizes he received at the end. He asked to go back again. I appreciate that they are going the extra mile to make a positive experience for kids in order to set them up for success in dental health later in life. I wish I had this type of experience in dental care as a kid!
Response from the owner:Thank you for your wonderful review, Nadine! We're thrilled to hear that your son had a positive experience with us. Our team is dedicated to making dental visits enjoyable for kids. We look forward to seeing you both again!

My 10 year old son has been going here for 4 years for dental and the last 2 years for ortho and he really likes all of the employees in this office. They really know how to treat kids. We just finished orthodontia and it was a smooth experience.
