We have been so pleased with care we have received by Dr Ray and his team! We have 3 kiddos in braces and the treatment has been very individualized. One of our kiddos had some anxiety regarding the process and the team was so patient to explain every step of the process and every instrument used.
Dr. Ray is very talented and so friendly. His office staff is cheery and very helpful. I highly recommend Dr. Ray and River Mountain Orthodontics!!
First time getting braces for a kid and everything is going great and looks amazing ! So glad we chose River Mountain Orthodontist! Dr. Ray does a great job explaining everything as we go, is great with kids, and We love the staff !There is never a long wait and their office is very clean .
I cannot imagine taking my children anywhere else for their ortho treatments from day one I felt like we were one of their own absolute outstanding service! Being a parent of multiple children that need treatment we really got lucky that we found this office and were blessed with such amazing people! Dr. McLagan called the very next day after the placement of the braces to offer support and advice it was just really nice to have a doctor take time from his extremely busy schedule to see how my child was doing! Margarita, Sami, Brittney, Mollie, they all treat you like family I look forward to every appointment to see their beautiful smiling faces waiting to take us in for our appointment, they always have the sweetest attitudes and we are truly blessed. I can see why my neighbor referred us to them it’s a no brainer!!
Awesome experience! Dr. Ray and his team are awesome! They are very friendly and informative throughout the whole process! My daughters smile looks amazing, thank you!
