Our happy patients

"Wonderful experience at Spring Orthodontics, and so impressed with Dr. Mathrani and Debbie, the treatment coordinator. From the personalized welcome message, to the full tour of their great space and technology, to their friendly and approachable demeanor, my child was completely at ease. As a mom, I appreciated that Dr. Mathrani provided a thoughtful and customized assessment — not a recommendation that was about profits. If you are looking for an orthodontic consultation, don’t hesitate, go to Spring!"

"I just started wearing Invisalign, and I could not ask for a better orthodontist than Dr. Mathrani. I had a ton of questions and concerns about the whole process, and she patiently answered all of my questions and gave me a lot of information to help me. Dr. Mathrani is very professional, and also has such a warm and inviting personality that makes the whole experience much more enjoyable."

"I have nothing but great things to say about this office. As someone, in my 30s, who was very nervous going into invisalign treatment, I can honestly say I wish I found Dr. Mathrani sooner. From consult, my initial scan (Yay! no gross molds), IPR , to receiving my trays , I can't be any more pleased with my experience."

"Our experience at Spring Orthodontics has been amazing! My 6 year old daughter had a severe overbite due to thumb sucking and I was referred to Dr Ro by our dentist. Dr Ro placed a device in my daughters mouth that had her overbite significantly reduced and broke the thumb sucking habit within 8 weeks! I am truly amazed by the results! Dr Ro was so great with my daughter and every visit has been a great experience- my daughter actually looks forward to going to the orthodontist! This place is a gem in Western..."

"Our family could not be happier with Dr. Ro and her practice! From the moment we walked in for our first consult, we knew we made the right choice! Dr. Ro is the best - very knowledgeable, super kind and so great with our girls! They truly love going in to see her for their visits! We highly recommend Dr. Ro (and Debbie too!) "
