I have brought all 5 of my kids here over the past 7 years and everyone at the office has been excellent to work with. Always professional and the kids enjoy everyone who works with them. They are efficient and always on time. Gabby continuously anticipates our needs and helps to make sure we are good to go with appointments, coverage and financial information.

After having braces as a child, I never wore my retainer. Fast forward, and I needed to get orthodontia as an adult due to a broken crown. Dr. Demko and her team were remarkable and fitted me into Adult Invisalign. Dr. Demko was a perfectionist when it came to my smile, and that is what one wants when doing this, especially as an adult. My smile looks better now than it did when I had my braces as a kid. I felt Dr. Demko and her team deeply cared about my needs as a patient and delivered accordingly.

We were referred to Demko Orthodontics before our first son had lost all his baby teeth yet. At that time, Jackie and her staff determined that it would be helpful to my son to extract some teeth to adjust the way his teeth were growing in to his mouth. They explained to my wife and me that it would help our son in the long-run and would reduce the cost of braces when that day would eventually come.

The entire staff at Demko has been great to deal with. Although my son -- 15 now -- would have preferred he not need braces, that had nothing to do with Jackie and her staff. He's going to get his braces off and move on to a retainer for a while within the next month. Just about the same time my younger son -- 12 now -- will get his own braces. It has been a great experience at Demko for our entire family. Even the A/R department has been understanding and accommodating.and that's not ordinary these days.
