Dr. Kristin and Dr. Alvarez are absolutely amazing. They both are exceptional at keeping the experience fun for their patients as well as educational. They have a passion for dentistry and for children that shows as any visit we have had. The staff is also very friendly and helpful. The office is run in a very clear, organized way so you feel comfortable and understand the process. The dental exam is thorough and they give special coins to the kids to be able to select a prize at the end which my kids absolutely love. Because of the emphasis from this office, my kids know that brushing their teeth daily is very important. Also they send multiple reminders about upcoming appointments via email and texts which are very helpful. I have had to move one of my children’s appointments a few weeks out due to a conflict and when I called the office, they were very understanding and I was able to move the appointment within 2 weeks. This is a great place and I would (and do) highly recommend it.

Dr. Kristin and Dr. Alvarez are amazing!!! We have 3 children, one of which has high functioning autism and they are absolutely amazing with all of our boys. They do a great job at making it a friendly and safe place. I wish adults could go here too!!!!

I tell my kids they have a dentist appointment and it’s all fist pumps! We love it there. The hygienists are great and Dr. Kristin/Dr. Alvarez are super stars. Not just nice, but thorough and they take the time to explain what they are looking for and what they see. There is a real sense of empowerment in so far as my kids feel responsible for their own dental health, it’s all in how they talk to them. TVs mounted to the ceiling don’t hurt either.
