This is the best pediatric dentistry office! I was a dental hygienist for over 20 years and very selective on which office I will take my son. I highly recommend this office.

Dr. John and his team are amazing! He thoroughly explained to us with visuals what was going on with our kids teeth, provided options. We are thankful to Dr. John and are happy we made the switch! I was tired of seeing a different dentist every time at my prior place. Ease of making appointments was also important.

Dr. De Lorme and his team are amazing! We recently took our son in for his second visit and had the best experience. I also went to Dr. De Lorme as a child and it’s fully circle bringing my own children now! My son felt comfortable and loved going to the dentist because of how friendly and accommodating everyone was! Would definitely recommend to anyone looking for an amazing pediatric dentist!

Dr. De Lorme and his team have an exceptional practice for children. They are all so sweet with my kids, get creative with them when the kids are resistant at times, and provides parents with great education on the health of their teeth and future plans etc. Their office is also so beautifully done with a fish tank, adorable Photo Booth that you can do with your kids after your dental visit and walls of prizes/toys- so so cute!

We are so happy with our experience at South OC Pediatric Dentistry! Our 6-month checkups and cleanings are always such a positive experience. The ladies at the front desk are warm and welcoming, and the hygienist is thorough, gentle, and takes such great care of our daughter’s teeth while always respecting and honoring our boundaries. Dr. DeLorme is encouraging, enthusiastic, and kind, and you can truly tell how much he cares about his patients. We always leave our visits feeling happy, reassured, and confident that our daughter is in great hands. We couldn’t be happier with our experience and highly recommend South OC Pediatric Dentistry!

I was referred to Dr. De Lorme by our previous pediatric dentist after we moved to the mission viejo area. My 3 kids have had two visits so far and the office staff, hygienists, and Dr. Lorme have exceeded my expectations. All the staff have been so nice and communicative and Dr. De Lorme really connects with the kids, provides a real comprehensive exam, and explains to both the kids and parents about what is going and potential next steps. He is kind and makes the kids feel safe and helps grownups be informed. We are so glad to have him as our pediatric dentist.

The Dr John takes the time to explain everything clearly and truly cares about his patients. We’re so grateful to have found a practice that makes dental visits such a positive experience. I highly recommend them to any family looking for exceptional care

Dr John has been amazing. We’ve been to other pediatric dentists who referred us out when dental work needed to be done and who made mountains out of molehills. I found Dr John because my 4 year old son had a cavity and I’m so glad I did. He was AMAZING with my son. His obvious experience gives him a very non-anxious presence which made everything easy and smooth. I realize with the reviews he already has that I’m definitely the last to show up to the party. Honestly, with the number of high reviews he has I figured his office must have found a way to rig the system. It turns out they are just really amazing and being really amazing is something easy for people to be excited about. If you are even close to considering a new dentist for your child, save yourself a ton of time and give him a call. You’ll be so glad you did. And say hi to the fish and starfish in the lobby!

As with Dr. Wu, our experience with Dr. De Lorme was fantastic. From scheduling the appointment to the appointment itself—our kid (six years old) and I as the father were thoroughly happy with the service!
