I absolutely love Gateway Little Smiles and the care they provide for my boys! Mo took great care of them and made sure they felt comfortable throughout their visits. He was patient, kind, and professional, and I truly appreciate the care and attention he gave my boys. The entire staff was friendly and welcoming, making the experience a positive one. As a mom, it means so much to know my children are in good hands and receiving excellent care. Thank you, Mo, and Gateway Little Smiles for taking such great care of my boys! I highly recommend Gateway Little Smiles to any parent looking for a wonderful dental office for their children! 🦷❤️

They did great with my 17 month old! Staff was informative and welcoming and the dentist is great with kids. I appreciate he made sure that the parent understands everything.

Our shy toddler was treated with warmth and patience as soon as we walked in the door! Her first appointment was very quick to help get used to visits, but everyone was still thorough and took time with our questions and concerns. The office is spacious and welcoming, with plenty to keep a little one distracted. Very happy that we chose a bit of a drive to Gateway Little Smiles!

Both of our toddler boys go here. They’re so patient and good with the littles. Our oldest is a social butterfly and doesn’t know a stranger, but our youngest is shy and very reserved until he warms up. They handle both of them so well. Explain things thoroughly. And we are so happy to start a healthy relationship with dental hygiene for both of our kids. We’re so glad we found little smiles. Oh and the welcome packet they send in the beginning is ADORABLE!
