    As always Narcy is amazing with my son. She makes him feel very comfortable with his dentist…read moreexperience and she's also great to talk to as an adult (hahah). She had no problem getting my son's X-ray's and then we Dr. Martinez checked out my son's teeth it was equally an enjoyable experience. We absolutely love Little Sprout and how we've felt like part of their ecosystem since my son was 6 months old. Thank you to all the amazing staff for all they've ever done for our family!

    Baby girl and I always have an amazing experience at this office, baby girl is always happy to go…read moreto the dentist. Which makes me so happy as her mommy lol. Dr. Martinez and his staff are amazing, they are always so friendly and they make baby girl feel so comfortable. She had a cleaning her 6 month check up a couple days ago and forgot to post about it. So doing so now, they have an arcade in the waiting area which is so cool, and plenty of seating for everyone. The parking is a bit small and it looks like a house from the front on Brea Blvd. its such a cute dentist office. They have tvs on the ceilings with movies playing they had red panda which is one of our favorites. They did xrays and cleaning and no cavities for baby girl again yay. She loves coming here, I enjoy bringing her, Dr. Martinez usually comes in at the end after they do the cleaning and xrays. Thank you always for your friendliness and making our kids feel at ease and comfortable. Been coming here for a while now, will continue to bring baby girl here for as long as we can. I noticed a few of my Yelp friends come here too that's awesome :) Have a beautiful day, be kind to everyone Aloha

    Today was my 16-month-old's very first dental visit, and we had a wonderful experience…read more Scheduling the appointment was incredibly easy, and all of the staff were so friendly and welcoming. The pricing was also very reasonable compared to other offices we looked into. The dentist (Dr. David Lee) took the time to explain everything thoroughly and provided us with a lot of helpful information. Most importantly, he was patient, gentle, and kind with my child throughout the visit. Since my little one is very shy around anyone outside of our family, I was honestly quite nervous about this first dental appointment. But everything went much more smoothly than I expected. Of course, my child was crying from the moment we walked into the lobby--haha--but the staff handled it so calmly and professionally. I'm grateful that they made my child's first dental experience such a positive one. I will definitely be recommending this office to many of my friends and family. Thank you for making our first visit such a great experience

    This was our first visit to Dr. Lee's office, referred by our primary family dentist for a specific…read moreconcern -- our 6-year-old had cavities between two teeth affecting both, with possible treatment ranging from a deep fill to a root canal or even extraction. From the moment we arrived, Dr. Lee was caring and compassionate. He communicated every step clearly and made sure our daughter felt comfortable throughout -- from the numbing gel and injection to the drilling, extraction, and filing. The office has movies playing, stuffed animals to hold, and attentive staff who genuinely made the experience less intimidating for a young child. In my experience with older kids, many dentists prefer to limit continuous dental work to 20-30 minutes depending on the child's tolerance. Thanks to our daughter's patience and Dr. Lee's efficiency, we were able to complete two significant procedures -- one on each side -- in just 45 minutes. The billing process was equally impressive. The staff clearly explained our insurance benefits and any potential remaining balance upfront. Of course, final costs can vary based on what X-rays and the physical exam reveal, but there were no surprises. Dr. Lee also walked me through multiple treatment options before and during the procedure, which I really appreciated. Fortunately, the least invasive option ended up being sufficient. We look forward to continuing care with Dr. Lee for our children.
